-{
-  "CoinGecko": "https://api.coingecko.com/api/v3",
-  "CoinCap": "https://api.coincap.io/v2",
-  "CoinStats": "https://api.coinstats.app",
-  "Cryptorank": "https://api.cryptorank.io/v1"

-
-## 🚀 چگونه API جدید اضافه کنیم؟
-
-### مثال: اضافه کردن CryptoCompare
-
-#### 1. در `app.py` به `API_PROVIDERS` اضافه کنید:
-```python
-API_PROVIDERS = {
-    "market_data": [
-        # ... موارد قبلی
-        {
-            "name": "CryptoCompare",
-            "base_url": "https://min-api.cryptocompare.com/data",
-            "endpoints": {
-                "price": "/price",
-                "multiple": "/pricemulti"
-            },
-            "auth": None,
-            "rate_limit": "100/hour",
-            "status": "active"
-        }
-    ]
-}
-```
-
-#### 2. تابع جدید برای fetch:
-```python
-async def get_cryptocompare_data():
-    async with aiohttp.ClientSession() as session:
-        url = "https://min-api.cryptocompare.com/data/pricemulti?fsyms=BTC,ETH&tsyms=USD"
-        data = await fetch_with_retry(session, url)
-        return data
-```
-
-#### 3. استفاده در endpoint:
-```python
-@app.get("/api/cryptocompare")
-async def cryptocompare():
-    data = await get_cryptocompare_data()
-    return {"data": data}
-```
-

+```
+
+---
+
+## 🚀 چگونه API جدید اضافه کنیم؟
+
+### مثال: اضافه کردن CryptoCompare
+
+#### 1. در `app.py` به `API_PROVIDERS` اضافه کنید:
+```python
+API_PROVIDERS = {
+    "market_data": [
+        # ... موارد قبلی
+        {
+            "name": "CryptoCompare",
+            "base_url": "https://min-api.cryptocompare.com/data",
+            "endpoints": {
+                "price": "/price",
+                "multiple": "/pricemulti"
+            },
+            "auth": None,
+            "rate_limit": "100/hour",
+            "status": "active"
+        }
+    ]
+}
+```
+
+#### 2. تابع جدید برای fetch:
+```python
+async def get_cryptocompare_data():
+    async with aiohttp.ClientSession() as session:
+        url = "https://min-api.cryptocompare.com/data/pricemulti?fsyms=BTC,ETH&tsyms=USD"
+        data = await fetch_with_retry(session, url)
+        return data
+```
+
+#### 3. استفاده در endpoint:
+```python
+@app.get("/api/cryptocompare")
+async def cryptocompare():
+    data = await get_cryptocompare_data()
+    return {"data": data}
+```
+
+---
+

-
-## Security & Validation
-
-### Input Validation
-
-1. **Hours Parameter:**
-   - Server-side clamping: `1 <= hours <= 168`
-   - Invalid types rejected with `422 Unprocessable Entity`
-   - Out-of-range values automatically clamped (no error)
-
-2. **Providers Parameter:**
-   - Allow-list enforcement: Only valid provider names accepted
-   - Max 5 providers enforced (excess silently truncated)
-   - Invalid names trigger `400 Bad Request` with detailed error
-   - SQL injection prevention: No raw SQL, parameterized queries only
-   - XSS prevention: Input sanitized (strip whitespace)
-
-3. **Rate Limiting (Recommended):**
-   - Implement: 60 requests/minute per IP for chart routes
-   - Use middleware or reverse proxy (nginx/cloudflare)
-
-### Security Measures Implemented
-
-✓ Allow-list validation for provider names
-✓ Parameter clamping (hours: 1-168)
-✓ Max provider limit (5)
-✓ SQL injection prevention (ORM with parameterized queries)
-✓ XSS prevention (input sanitization)
-✓ Comprehensive error handling with safe error messages
-✓ Logging of all chart requests for monitoring
-✓ No sensitive data exposure in responses
-
-### Edge Cases Handled
-
-- Empty provider list → Returns default providers
-- Unknown provider → 400 with valid options listed
-- Hours out of bounds → Clamped to [1, 168]
-- No data available → Returns empty series or 999.0 staleness
-- Provider with no rate limit → Returns null limit_value
-- Whitespace in provider names → Trimmed automatically
-- Mixed valid/invalid providers → Rejects entire request
-
----
-
-## Testing
-
-### Automated Tests
-
-Run the comprehensive test suite:
-
-```bash
-# Run all chart tests
-pytest tests/test_charts.py -v
-
-# Run specific test class
-pytest tests/test_charts.py::TestRateLimitHistory -v
-
-# Run with coverage
-pytest tests/test_charts.py --cov=api --cov-report=html
-```
-
-**Test Coverage:**
-
-- ✓ Default parameter behavior
-- ✓ Custom time ranges (48h, 72h)
-- ✓ Provider selection and filtering
-- ✓ Response schema validation
-- ✓ Percentage range validation [0-100]
-- ✓ Timestamp format validation
-- ✓ Status derivation logic
-- ✓ Edge cases (invalid providers, hours clamping)
-- ✓ Security (SQL injection, XSS prevention)
-- ✓ Performance (response time < 500ms)
-- ✓ Concurrent request handling
-
-### Manual Sanity Checks
-
-Run the CLI sanity check script:
-
-```bash
-# Ensure backend is running
-python app.py &
-
-# Run sanity checks
-./tests/sanity_checks.sh
-```
-
-**Checks performed:**
-
-1. Rate limit history (default params)
-2. Freshness history (default params)
-3. Custom time ranges
-4. Response schema validation
-5. Invalid provider rejection
-6. Hours parameter clamping
-7. Performance measurement
-8. Edge case handling
-
----
-
-## Performance Targets
-
-### Response Time (P95)
-
-| Environment | Target | Conditions |
-|-------------|--------|------------|
-| Production | < 200ms | 24h / 5 providers |
-| Development | < 500ms | 24h / 5 providers |
-
-### Optimization Strategies
-
-1. **Database Indexing:**
-   - Indexed: `timestamp`, `provider_id` columns
-   - Composite indexes on frequently queried combinations
-
-2. **Query Optimization:**
-   - Hourly bucketing done in-memory (fast)
-   - Limited to 168 hours max (1 week)
-   - Provider limit enforced early (max 5)
-
-3. **Caching (Future Enhancement):**
-   - Consider Redis cache for 1-minute TTL
-   - Cache key: `chart:type:hours:providers`
-   - Invalidate on new data ingestion
-
-4. **Connection Pooling:**
-   - SQLAlchemy pool size: 10
-   - Max overflow: 20
-   - Recycle connections every 3600s
-

-
-## Troubleshooting
-
-### Common Issues
-
-**1. Empty series returned**
-
-- Check if providers have data in the time range
-- Verify provider names are correct (case-sensitive)
-- Ensure database has historical data
-
-**2. Response time > 500ms**
-
-- Check database indexes exist
-- Reduce `hours` parameter
-- Limit number of providers
-- Consider adding caching layer
-
-**3. 400 Bad Request on valid provider**
-
-- Verify provider is in database: `SELECT name FROM providers`
-- Check for typos or case mismatch
-- Ensure provider has not been renamed
-
-**4. Missing data points (gaps in series)**
-
-- Normal behavior: gaps filled with zeros/999.0
-- Check data collection scheduler is running
-- Review logs for collection failures
-
----

+```
+
+**Error Responses:**
+
+- `400 Bad Request`: Invalid provider name
+- `422 Unprocessable Entity`: Invalid parameter type
+- `500 Internal Server Error`: Database or processing error
+
+---
+
+## Security & Validation
+
+### Input Validation
+
+1. **Hours Parameter:**
+   - Server-side clamping: `1 <= hours <= 168`
+   - Invalid types rejected with `422 Unprocessable Entity`
+   - Out-of-range values automatically clamped (no error)
+
+2. **Providers Parameter:**
+   - Allow-list enforcement: Only valid provider names accepted
+   - Max 5 providers enforced (excess silently truncated)
+   - Invalid names trigger `400 Bad Request` with detailed error
+   - SQL injection prevention: No raw SQL, parameterized queries only
+   - XSS prevention: Input sanitized (strip whitespace)
+
+3. **Rate Limiting (Recommended):**
+   - Implement: 60 requests/minute per IP for chart routes
+   - Use middleware or reverse proxy (nginx/cloudflare)
+
+### Security Measures Implemented
+
+✓ Allow-list validation for provider names
+✓ Parameter clamping (hours: 1-168)
+✓ Max provider limit (5)
+✓ SQL injection prevention (ORM with parameterized queries)
+✓ XSS prevention (input sanitization)
+✓ Comprehensive error handling with safe error messages
+✓ Logging of all chart requests for monitoring
+✓ No sensitive data exposure in responses
+
+### Edge Cases Handled
+
+- Empty provider list → Returns default providers
+- Unknown provider → 400 with valid options listed
+- Hours out of bounds → Clamped to [1, 168]
+- No data available → Returns empty series or 999.0 staleness
+- Provider with no rate limit → Returns null limit_value
+- Whitespace in provider names → Trimmed automatically
+- Mixed valid/invalid providers → Rejects entire request
+
+---
+
+## Testing
+
+### Automated Tests
+
+Run the comprehensive test suite:
+
+```bash
+# Run all chart tests
+pytest tests/test_charts.py -v
+
+# Run specific test class
+pytest tests/test_charts.py::TestRateLimitHistory -v
+
+# Run with coverage
+pytest tests/test_charts.py --cov=api --cov-report=html
+```
+
+**Test Coverage:**
+
+- ✓ Default parameter behavior
+- ✓ Custom time ranges (48h, 72h)
+- ✓ Provider selection and filtering
+- ✓ Response schema validation
+- ✓ Percentage range validation [0-100]
+- ✓ Timestamp format validation
+- ✓ Status derivation logic
+- ✓ Edge cases (invalid providers, hours clamping)
+- ✓ Security (SQL injection, XSS prevention)
+- ✓ Performance (response time < 500ms)
+- ✓ Concurrent request handling
+
+### Manual Sanity Checks
+
+Run the CLI sanity check script:
+
+```bash
+# Ensure backend is running
+python app.py &
+
+# Run sanity checks
+./tests/sanity_checks.sh
+```
+
+**Checks performed:**
+
+1. Rate limit history (default params)
+2. Freshness history (default params)
+3. Custom time ranges
+4. Response schema validation
+5. Invalid provider rejection
+6. Hours parameter clamping
+7. Performance measurement
+8. Edge case handling
+
+---
+
+## Performance Targets
+
+### Response Time (P95)
+
+| Environment | Target | Conditions |
+|-------------|--------|------------|
+| Production | < 200ms | 24h / 5 providers |
+| Development | < 500ms | 24h / 5 providers |
+
+### Optimization Strategies
+
+1. **Database Indexing:**
+   - Indexed: `timestamp`, `provider_id` columns
+   - Composite indexes on frequently queried combinations
+
+2. **Query Optimization:**
+   - Hourly bucketing done in-memory (fast)
+   - Limited to 168 hours max (1 week)
+   - Provider limit enforced early (max 5)
+
+3. **Caching (Future Enhancement):**
+   - Consider Redis cache for 1-minute TTL
+   - Cache key: `chart:type:hours:providers`
+   - Invalidate on new data ingestion
+
+4. **Connection Pooling:**
+   - SQLAlchemy pool size: 10
+   - Max overflow: 20
+   - Recycle connections every 3600s
+

+        }
+    }
+});
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+**1. Empty series returned**
+
+- Check if providers have data in the time range
+- Verify provider names are correct (case-sensitive)
+- Ensure database has historical data
+
+**2. Response time > 500ms**

-```
-
----
-
-## 📝 Integration with Existing System
-
-The new collectors integrate seamlessly with the existing monitoring system:
-
-1. **Database Models** (`database/models.py`) - Already support all data types
-2. **API Endpoints** (`api/endpoints.py`) - Can expose new collector data
-3. **Gradio UI** - Can visualize new data sources
-4. **Unified Config** (`backend/services/unified_config_loader.py`) - Manages all sources
-
-### Example Integration:
-
-```python
-from collectors.master_collector import DataSourceCollector
-from database.models import DataCollection
-from monitoring.scheduler import scheduler
-
-# Add to existing scheduler
-async def scheduled_collection():
-    collector = DataSourceCollector()
-    results = await collector.collect_all_data()
-
-    # Store in database
-    for category, data in results['data'].items():
-        collection = DataCollection(
-            provider=category,
-            data=data,
-            success=True
-        )
-        session.add(collection)
-
-    session.commit()
-
-# Schedule it
-scheduler.add_job(scheduled_collection, 'interval', minutes=5)
-```
-
----
-
-## 🎯 Next Steps
-
-1. **Enable Paid APIs**: Add API keys for premium data sources
-2. **Custom Alerts**: Set up alerts for whale transactions, news keywords
-3. **Data Analysis**: Build dashboards visualizing collected data
-4. **Machine Learning**: Use collected data for price predictions
-5. **Export Features**: Export data to CSV, JSON, or databases
-
----
-
-## 🐛 Troubleshooting
-
-### Issue: RSS Feed Parsing Errors
-**Solution**: Install feedparser: `pip install feedparser`
-
-### Issue: RPC Connection Timeouts
-**Solution**: Some public RPCs rate-limit. Use Infura/Alchemy with API keys.
-
-### Issue: Placeholder Data for Sentiment APIs
-**Solution**: These require paid subscriptions. API structure is ready when you get keys.
-
-### Issue: Master Collector Taking Too Long
-**Solution**: Reduce concurrent sources or increase timeouts in `utils/api_client.py`

----
-
-## Post-Deployment Testing
-
-### 1. Test Health Endpoint
-
-```bash
-curl https://your-deployment-url.com/health
-```
-
-Expected response:
-```json
-{
-  "status": "healthy",
-  "timestamp": "2025-11-10T...",
-  "resources_loaded": true,
-  "database_connected": true
-}
-```
-
-### 2. Test Resource Listing
-
-```bash
-curl https://your-deployment-url.com/resources
-```
-
-### 3. Test Query Endpoint
-
-```bash
-curl -X POST https://your-deployment-url.com/query \
-  -H "Content-Type: application/json" \
-  -d '{
-    "resource_type": "market_data",
-    "resource_name": "coingecko",
-    "endpoint": "/simple/price",
-    "params": {
-      "ids": "bitcoin",
-      "vs_currencies": "usd"
-    }
-  }'
-```
-
-### 4. Test Status Monitoring
-
-```bash
-curl https://your-deployment-url.com/status
-```
-
-### 5. Run Full Test Suite
-
-From your local machine:
-
-```bash
-# Update BASE_URL in test_aggregator.py
-# Change: BASE_URL = "http://localhost:7860"
-# To: BASE_URL = "https://your-deployment-url.com"
-
-# Run tests
-python test_aggregator.py
-```
-
----
-
-## Performance Optimization
-
-### 1. Enable Caching
-
-Add Redis for caching (optional):
-
-```python
-import redis
-import json
-
-# Connect to Redis
-redis_client = redis.Redis(host='localhost', port=6379, decode_responses=True)
-
-# Cache resource data
-def get_cached_data(key, ttl=300):
-    cached = redis_client.get(key)
-    if cached:
-        return json.loads(cached)
-    return None
-
-def set_cached_data(key, data, ttl=300):
-    redis_client.setex(key, ttl, json.dumps(data))
-```
-
-### 2. Use Connection Pooling
-
-Already implemented with `aiohttp.ClientSession`
-
-### 3. Add Rate Limiting
-
-Install:
-```bash
-pip install slowapi
-```
-
-Add to `app.py`:
-```python
-from slowapi import Limiter, _rate_limit_exceeded_handler
-from slowapi.util import get_remote_address
-from slowapi.errors import RateLimitExceeded
-
-limiter = Limiter(key_func=get_remote_address)
-app.state.limiter = limiter
-app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
-
-@app.post("/query")
-@limiter.limit("60/minute")
-async def query_resource(request: Request, query: ResourceQuery):
-    # ... existing code
-```
-
-### 4. Add Monitoring
-
-Use Sentry for error tracking:
-
-```bash
-pip install sentry-sdk
-```
-
-```python
-import sentry_sdk
-from sentry_sdk.integrations.fastapi import FastApiIntegration
-
-sentry_sdk.init(
-    dsn="your-sentry-dsn",
-    integrations=[FastApiIntegration()],
-    traces_sample_rate=1.0,
-)
-```
-
----
-
-## Security Best Practices
-
-### 1. API Key Management
-
-Store API keys in environment variables:
-
-```python
-import os
-
-API_KEYS = {
-    'etherscan': os.getenv('ETHERSCAN_API_KEY', 'default-key'),
-    'coinmarketcap': os.getenv('CMC_API_KEY', 'default-key'),
-}
-```
-
-### 2. Enable HTTPS
-
-Most platforms (Hugging Face, Heroku, etc.) provide HTTPS by default.
-
-For self-hosted, use Let's Encrypt:
-
-```bash
-# Install Certbot
-sudo apt install certbot python3-certbot-nginx
-
-# Get certificate
-sudo certbot --nginx -d your-domain.com
-```
-
-### 3. Add Authentication (Optional)
-
-```bash
-pip install python-jose[cryptography] passlib[bcrypt]
-```
-
-```python
-from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials
-from fastapi import Security
-
-security = HTTPBearer()
-
-@app.post("/query")
-async def query_resource(
-    query: ResourceQuery,
-    credentials: HTTPAuthorizationCredentials = Security(security)
-):
-    # Verify token
-    if credentials.credentials != "your-secret-token":
-        raise HTTPException(status_code=401, detail="Invalid token")
-    # ... existing code
-```
-
----
-
-## Monitoring & Maintenance
-
-### 1. Monitor Logs
-
-Hugging Face Spaces:
-- View logs in the Space settings → "Logs" tab
-
-Docker:
-```bash
-docker logs -f crypto-aggregator
-```
-
-Systemd:
-```bash
-journalctl -u crypto-aggregator -f
-```
-
-### 2. Database Maintenance
-
-Backup database regularly:
-
-```bash
-# Local backup
-cp history.db history_backup_$(date +%Y%m%d).db
-
-# Remote backup
-scp user@server:/path/to/history.db ./backups/
-```
-
-Clean old records:
-
-```sql
--- Remove records older than 30 days
-DELETE FROM query_history WHERE timestamp < datetime('now', '-30 days');
-DELETE FROM resource_status WHERE last_check < datetime('now', '-30 days');
-```
-
-### 3. Update Resources
-
-To add new resources, update `all_apis_merged_2025.json` and redeploy.
-
-### 4. Health Checks
-
-Set up automated health checks:
-
-```bash
-# Cron job (every 5 minutes)
-*/5 * * * * curl https://your-deployment-url.com/health || echo "API is down!"
-```
-
-Use UptimeRobot or similar service for monitoring.
-
----
-
-## Troubleshooting
-
-### Issue: Server won't start
-
-**Solution:**
-```bash
-# Check if port 7860 is in use
-lsof -i :7860
-
-# Kill existing process
-kill -9 $(lsof -t -i:7860)
-
-# Or use a different port
-PORT=8000 python app.py
-```
-
-### Issue: Database locked
-
-**Solution:**
-```bash
-# Stop all instances
-pkill -f app.py
-
-# Remove lock (if exists)
-rm history.db-journal
-
-# Restart
-python app.py
-```
-
-### Issue: High memory usage
-
-**Solution:**
-- Add connection limits
-- Implement request queuing
-- Scale horizontally with multiple instances
-
-### Issue: API rate limits
-
-**Solution:**
-- Implement caching
-- Add multiple API keys for rotation
-- Use fallback resources
-
----
-
-## Scaling
-
-### Horizontal Scaling
-
-Use a load balancer with multiple instances:
-
-```yaml
-# docker-compose-scaled.yml
-version: '3.8'
-
-services:
-  aggregator:
-    build: .
-    deploy:
-      replicas: 3
-    environment:
-      - WORKER_ID=${HOSTNAME}
-
-  nginx:
-    image: nginx:alpine
-    ports:
-      - "80:80"
-    volumes:
-      - ./nginx.conf:/etc/nginx/nginx.conf
-    depends_on:
-      - aggregator
-```
-
-### Vertical Scaling
-
-Increase resources on your hosting platform:
-- Hugging Face: Upgrade to paid tier
-- AWS: Use larger EC2 instance
-- Docker: Adjust container resources
-
----
-
-## Support
-
-For issues or questions:
-1. Check `/health` endpoint
-2. Review application logs
-3. Test individual resources with `/status`
-4. Verify database with SQLite browser
-
----
-
-## Next Steps
-
-After deployment:
-
-1. **Integrate with your main app** using the provided client examples
-2. **Set up monitoring** with health checks and alerts
-3. **Configure backups** for the history database
-4. **Add custom resources** by updating the JSON file
-5. **Implement caching** for frequently accessed data
-6. **Enable authentication** if needed for security
-
----
-
-**Congratulations! Your Crypto Resource Aggregator is now deployed and ready to use!** 🚀

+  "status": "healthy",
+  "timestamp": "2025-11-10T...",
+  "resources_loaded": true,
+  "database_connected": true
+}
+```
+
+### 2. Test Resource Listing
+
+```bash
+curl https://your-deployment-url.com/resources
+```
+
+### 3. Test Query Endpoint
+
+```bash
+curl -X POST https://your-deployment-url.com/query \
+  -H "Content-Type: application/json" \
+  -d '{
+    "resource_type": "market_data",
+    "resource_name": "coingecko",
+    "endpoint": "/simple/price",
+    "params": {
+      "ids": "bitcoin",
+      "vs_currencies": "usd"
+    }
+  }'
+```
+
+### 4. Test Status Monitoring
+
+```bash
+curl https://your-deployment-url.com/status
+```
+
+### 5. Run Full Test Suite
+
+From your local machine:
+
+```bash
+# Update BASE_URL in test_aggregator.py
+# Change: BASE_URL = "http://localhost:7860"
+# To: BASE_URL = "https://your-deployment-url.com"
+
+# Run tests
+python test_aggregator.py
+```
+
+---
+
+## Performance Optimization
+
+### 1. Enable Caching
+
+Add Redis for caching (optional):
+
+```python
+import redis
+import json
+
+# Connect to Redis
+redis_client = redis.Redis(host='localhost', port=6379, decode_responses=True)
+
+# Cache resource data
+def get_cached_data(key, ttl=300):
+    cached = redis_client.get(key)
+    if cached:
+        return json.loads(cached)
+    return None
+
+def set_cached_data(key, data, ttl=300):
+    redis_client.setex(key, ttl, json.dumps(data))
+```
+
+### 2. Use Connection Pooling
+
+Already implemented with `aiohttp.ClientSession`
+
+### 3. Add Rate Limiting
+
+Install:
+```bash
+pip install slowapi
+```
+
+Add to `app.py`:
+```python
+from slowapi import Limiter, _rate_limit_exceeded_handler
+from slowapi.util import get_remote_address
+from slowapi.errors import RateLimitExceeded
+
+limiter = Limiter(key_func=get_remote_address)
+app.state.limiter = limiter
+app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
+
+@app.post("/query")
+@limiter.limit("60/minute")
+async def query_resource(request: Request, query: ResourceQuery):
+    # ... existing code
+```
+
+### 4. Add Monitoring
+
+Use Sentry for error tracking:
+
+```bash
+pip install sentry-sdk
+```
+
+```python
+import sentry_sdk
+from sentry_sdk.integrations.fastapi import FastApiIntegration
+
+sentry_sdk.init(
+    dsn="your-sentry-dsn",
+    integrations=[FastApiIntegration()],
+    traces_sample_rate=1.0,
+)
+```
+
+---
+
+## Security Best Practices
+
+### 1. API Key Management
+
+Store API keys in environment variables:
+
+```python
+import os
+
+API_KEYS = {
+    'etherscan': os.getenv('ETHERSCAN_API_KEY', 'default-key'),
+    'coinmarketcap': os.getenv('CMC_API_KEY', 'default-key'),
+}
+```
+
+### 2. Enable HTTPS
+
+Most platforms (Hugging Face, Heroku, etc.) provide HTTPS by default.
+
+For self-hosted, use Let's Encrypt:
+
+```bash
+# Install Certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Get certificate
+sudo certbot --nginx -d your-domain.com
+```
+
+### 3. Add Authentication (Optional)
+
+```bash
+pip install python-jose[cryptography] passlib[bcrypt]
+```
+
+```python
+from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials
+from fastapi import Security
+
+security = HTTPBearer()
+
+@app.post("/query")
+async def query_resource(
+    query: ResourceQuery,
+    credentials: HTTPAuthorizationCredentials = Security(security)
+):
+    # Verify token
+    if credentials.credentials != "your-secret-token":
+        raise HTTPException(status_code=401, detail="Invalid token")
+    # ... existing code
+```
+
+---
+
+## Monitoring & Maintenance
+
+### 1. Monitor Logs
+
+Hugging Face Spaces:
+- View logs in the Space settings → "Logs" tab
+
+Docker:
+```bash
+docker logs -f crypto-aggregator
+```
+
+Systemd:
+```bash
+journalctl -u crypto-aggregator -f
+```
+
+### 2. Database Maintenance
+
+Backup database regularly:
+
+```bash
+# Local backup
+cp history.db history_backup_$(date +%Y%m%d).db
+
+# Remote backup
+scp user@server:/path/to/history.db ./backups/
+```
+
+Clean old records:
+
+```sql
+-- Remove records older than 30 days
+DELETE FROM query_history WHERE timestamp < datetime('now', '-30 days');
+DELETE FROM resource_status WHERE last_check < datetime('now', '-30 days');
+```
+
+### 3. Update Resources
+
+To add new resources, update `all_apis_merged_2025.json` and redeploy.
+
+### 4. Health Checks
+
+Set up automated health checks:
+
+```bash
+# Cron job (every 5 minutes)
+*/5 * * * * curl https://your-deployment-url.com/health || echo "API is down!"
+```
+
+Use UptimeRobot or similar service for monitoring.
+
+---
+
+## Troubleshooting
+
+### Issue: Server won't start
+
+**Solution:**
+```bash
+# Check if port 7860 is in use
+lsof -i :7860
+
+# Kill existing process
+kill -9 $(lsof -t -i:7860)
+
+# Or use a different port
+PORT=8000 python app.py
+```
+
+### Issue: Database locked
+
+**Solution:**
+```bash
+# Stop all instances
+pkill -f app.py
+
+# Remove lock (if exists)
+rm history.db-journal
+
+# Restart
+python app.py
+```
+
+### Issue: High memory usage
+
+**Solution:**
+- Add connection limits
+- Implement request queuing
+- Scale horizontally with multiple instances
+
+### Issue: API rate limits
+
+**Solution:**
+- Implement caching
+- Add multiple API keys for rotation
+- Use fallback resources
+
+---
+
+## Scaling
+
+### Horizontal Scaling
+
+Use a load balancer with multiple instances:
+
+```yaml
+# docker-compose-scaled.yml
+version: '3.8'
+
+services:
+  aggregator:
+    build: .
+    deploy:
+      replicas: 3
+    environment:
+      - WORKER_ID=${HOSTNAME}
+
+  nginx:
+    image: nginx:alpine
+    ports:
+      - "80:80"
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf
+    depends_on:
+      - aggregator
+```
+
+### Vertical Scaling
+
+Increase resources on your hosting platform:
+- Hugging Face: Upgrade to paid tier
+- AWS: Use larger EC2 instance
+- Docker: Adjust container resources
+
+---
+
+## Support
+
+For issues or questions:
+1. Check `/health` endpoint
+2. Review application logs
+3. Test individual resources with `/status`
+4. Verify database with SQLite browser
+
+---
+
+## Next Steps
+
+After deployment:
+
+1. **Integrate with your main app** using the provided client examples
+2. **Set up monitoring** with health checks and alerts
+3. **Configure backups** for the history database
+4. **Add custom resources** by updating the JSON file
+5. **Implement caching** for frequently accessed data
+6. **Enable authentication** if needed for security
+
+---
+
+**Congratulations! Your Crypto Resource Aggregator is now deployed and ready to use!** 🚀

-  - `crypto_resources_unified_2025-11-11.json` (200+ APIs)
-  - `all_apis_merged_2025.json`
-  - `ultimate_crypto_pipeline_2025_NZasinich.json`
-- Automatic API key extraction
-- Category-based organization
-- Update type classification (realtime, periodic, scheduled)
-- Schedule management for each API
-- Import/Export functionality
-
-**Usage:**
-```python
-from backend.services.unified_config_loader import UnifiedConfigLoader
-
-loader = UnifiedConfigLoader()
-
-# Get all APIs
-all_apis = loader.get_all_apis()
-
-# Get APIs by category
-market_data_apis = loader.get_apis_by_category('market_data')
-
-# Get APIs by update type
-realtime_apis = loader.get_realtime_apis()
-periodic_apis = loader.get_periodic_apis()
-
-# Add custom API
-loader.add_custom_api({
-    'id': 'custom_api',
-    'name': 'Custom API',
-    'category': 'custom',
-    'base_url': 'https://api.example.com',
-    'update_type': 'periodic',
-    'enabled': True
-})
-```
-
-### 2. Enhanced Scheduling System
-
-**File:** `backend/services/scheduler_service.py`
-
-Advanced scheduler that manages periodic and real-time data updates with automatic error handling and retry logic.

-- **Real-time Updates:** WebSocket connections for instant data
-- **Scheduled Updates:** Less frequent updates for HuggingFace and other resources
-- **Smart Retry:** Automatic interval adjustment on failures
-- **Callbacks:** Register callbacks for data updates
-- **Force Updates:** Manually trigger immediate updates
-
-**Update Types:**
-- `realtime` (0s interval): WebSocket - always connected
-- `periodic` (60s interval): Regular polling for market data
-- `scheduled` (3600s interval): Hourly updates for HF models/datasets
-- `daily` (86400s interval): Once per day
-
-**Usage:**
-```python
-from backend.services.scheduler_service import SchedulerService
-
-scheduler = SchedulerService(config_loader, db_manager)
-
-# Start scheduler
-await scheduler.start()
-
-# Update schedule
-scheduler.update_task_schedule('coingecko', interval=120, enabled=True)
-
-# Force update
-success = await scheduler.force_update('coingecko')
-
-# Register callback
-def on_data_update(api_id, data):
-    print(f"Data updated for {api_id}")
-
-scheduler.register_callback('coingecko', on_data_update)
-
-# Get task status
-status = scheduler.get_task_status('coingecko')
-
-# Export schedules
-scheduler.export_schedules('schedules_backup.json')
-```
-
-### 3. Data Persistence Service
-
-**File:** `backend/services/persistence_service.py`

-**Usage:**
-```python
-from backend.services.persistence_service import PersistenceService
-
-persistence = PersistenceService(db_manager)
-
-# Save data
-await persistence.save_api_data(
-    'coingecko',
-    {'price': 50000},
-    metadata={'category': 'market_data'}
-)
-
-# Get cached data
-data = persistence.get_cached_data('coingecko')
-
-# Get history
-history = persistence.get_history('coingecko', limit=100)
-
-# Export to JSON
-await persistence.export_to_json('export.json', include_history=True)
-
-# Export to CSV
-await persistence.export_to_csv('export.csv', flatten=True)
-
-# Create backup
-backup_file = await persistence.backup_all_data()
-
-# Restore from backup
-await persistence.restore_from_backup(backup_file)
-
-# Cleanup old data (7 days)
-removed = await persistence.cleanup_old_data(days=7)
-```
-
-### 4. Real-time WebSocket Service

+# Enhanced Crypto Data Tracker - New Features
+
+## 🚀 Overview
+
+This document describes the major enhancements added to the crypto data tracking system, including unified configuration management, advanced scheduling, real-time updates via WebSockets, and comprehensive data persistence.
+
+## ✨ New Features
+
+### 1. Unified Configuration Loader
+
+**File:** `backend/services/unified_config_loader.py`
+
+The unified configuration loader automatically imports and manages all API sources from JSON configuration files at the project root.
+
+**Features:**
+- Loads from multiple JSON config files:
+  - `crypto_resources_unified_2025-11-11.json` (200+ APIs)
+  - `all_apis_merged_2025.json`
+  - `ultimate_crypto_pipeline_2025_NZasinich.json`
+- Automatic API key extraction
+- Category-based organization
+- Update type classification (realtime, periodic, scheduled)
+- Schedule management for each API
+- Import/Export functionality
+
+**Usage:**
+```python
+from backend.services.unified_config_loader import UnifiedConfigLoader
+
+loader = UnifiedConfigLoader()
+
+# Get all APIs
+all_apis = loader.get_all_apis()
+
+# Get APIs by category
+market_data_apis = loader.get_apis_by_category('market_data')
+
+# Get APIs by update type
+realtime_apis = loader.get_realtime_apis()
+periodic_apis = loader.get_periodic_apis()
+
+# Add custom API
+loader.add_custom_api({
+    'id': 'custom_api',
+    'name': 'Custom API',
+    'category': 'custom',
+    'base_url': 'https://api.example.com',
+    'update_type': 'periodic',
+    'enabled': True
+})
+```
+
+### 2. Enhanced Scheduling System
+
+**File:** `backend/services/scheduler_service.py`
+
+Advanced scheduler that manages periodic and real-time data updates with automatic error handling and retry logic.
+
+**Features:**
+- **Periodic Updates:** Schedule APIs to update at specific intervals
+- **Real-time Updates:** WebSocket connections for instant data
+- **Scheduled Updates:** Less frequent updates for HuggingFace and other resources
+- **Smart Retry:** Automatic interval adjustment on failures
+- **Callbacks:** Register callbacks for data updates
+- **Force Updates:** Manually trigger immediate updates
+
+**Update Types:**
+- `realtime` (0s interval): WebSocket - always connected
+- `periodic` (60s interval): Regular polling for market data
+- `scheduled` (3600s interval): Hourly updates for HF models/datasets
+- `daily` (86400s interval): Once per day
+
+**Usage:**
+```python
+from backend.services.scheduler_service import SchedulerService
+
+scheduler = SchedulerService(config_loader, db_manager)
+
+# Start scheduler
+await scheduler.start()
+
+# Update schedule
+scheduler.update_task_schedule('coingecko', interval=120, enabled=True)
+
+# Force update
+success = await scheduler.force_update('coingecko')
+
+# Register callback
+def on_data_update(api_id, data):
+    print(f"Data updated for {api_id}")
+
+scheduler.register_callback('coingecko', on_data_update)
+
+# Get task status
+status = scheduler.get_task_status('coingecko')
+
+# Export schedules
+scheduler.export_schedules('schedules_backup.json')
+```
+
+### 3. Data Persistence Service
+
+**File:** `backend/services/persistence_service.py`
+
+Comprehensive data persistence with multiple export formats and automatic backups.
+
+**Features:**
+- In-memory caching for quick access
+- Historical data tracking (configurable limit)
+- Export to JSON, CSV formats
+- Automatic backups
+- Database integration (SQLAlchemy)
+- Data cleanup utilities
+
+**Usage:**
+```python
+from backend.services.persistence_service import PersistenceService
+
+persistence = PersistenceService(db_manager)
+
+# Save data
+await persistence.save_api_data(
+    'coingecko',
+    {'price': 50000},
+    metadata={'category': 'market_data'}
+)
+
+# Get cached data
+data = persistence.get_cached_data('coingecko')
+
+# Get history
+history = persistence.get_history('coingecko', limit=100)
+
+# Export to JSON
+await persistence.export_to_json('export.json', include_history=True)
+
+# Export to CSV
+await persistence.export_to_csv('export.csv', flatten=True)
+
+# Create backup
+backup_file = await persistence.backup_all_data()
+
+# Restore from backup
+await persistence.restore_from_backup(backup_file)
+
+# Cleanup old data (7 days)
+removed = await persistence.cleanup_old_data(days=7)
+```
+
+### 4. Real-time WebSocket Service

-
-## Troubleshooting
-
-### Build Fails
-
-1. Check Docker logs in HF Spaces
-2. Verify `requirements.txt` has all dependencies
-3. Ensure Dockerfile uses Python 3.10
-4. Check for syntax errors in Python files
-
-### Application Won't Start
-
-1. Check health endpoint: `https://your-space-url/health`
-2. Review application logs in HF Spaces
-3. Verify port 7860 is exposed in Dockerfile
-4. Check environment variables are set correctly
-
-### WebSocket Connections Fail
-
-1. Ensure your Space URL uses HTTPS
-2. WebSockets automatically upgrade to WSS on HTTPS
-3. Check browser console for connection errors
-4. Verify CORS settings in `app.py`
-
-### Sentiment Analysis Not Working
-
-1. Set `HUGGINGFACE_TOKEN` in Space secrets
-2. Verify models are accessible: `ElKulako/cryptobert`, `kk08/CryptoBERT`
-3. Check HF console at `/hf_console.html`
-4. Review logs for model download errors
-
-### Performance Issues
-
-1. Increase Space hardware tier (if available)
-2. Reduce number of concurrent API monitors
-3. Adjust `HF_REGISTRY_REFRESH_SEC` to longer interval
-4. Consider disabling sentiment analysis if not needed
-
-## Resource Requirements
-
-**Minimum (Free Tier):**
-- 2 CPU cores
-- 2GB RAM
-- 1GB disk space
-
-**Recommended:**
-- 4 CPU cores
-- 4GB RAM
-- 2GB disk space
-- For better ML model performance
-
-## Updating Your Space
-
-```bash
-# Pull latest changes
-git pull
-
-# Make your modifications
-# ...
-
-# Commit and push
-git add .
-git commit -m "Update: description of changes"
-git push
-```
-
-HuggingFace will automatically rebuild and redeploy.
-
-## Security Best Practices
-
-1. **Use HF Secrets** for sensitive data (API keys, tokens)
-2. **Don't commit** `.env` files with actual keys
-3. **Review API keys** permissions (read-only when possible)
-4. **Monitor usage** of external APIs to avoid rate limits
-5. **Keep dependencies updated** for security patches
-
-## Advanced Configuration
-
-### Custom ML Models
-
-To use custom sentiment analysis models:
-
-```bash
-# Set environment variables in HF Spaces
-SENTIMENT_SOCIAL_MODEL=your-username/your-model
-SENTIMENT_NEWS_MODEL=your-username/another-model
-```
-
-### Custom Port (Not Recommended for HF Spaces)
-
-HuggingFace Spaces requires port 7860. Don't change unless deploying elsewhere.
-
-### Multiple Workers
-
-Edit Dockerfile CMD:
-```dockerfile
-CMD ["uvicorn", "app:app", "--host", "0.0.0.0", "--port", "7860", "--workers", "2"]
-```
-
-**Note**: More workers = more memory usage. Adjust based on Space tier.

-# Frontend-Backend Integration Summary
-
-## Overview
-This document summarizes the complete integration between the frontend (index.html) and backend (FastAPI) for the Crypto API Monitoring System. All components from the integration mapping document have been implemented and verified.
-
----
-
-## ✅ COMPLETED INTEGRATIONS
-
-### 1. **KPI Cards (Dashboard Header)**
-- **Frontend**: `index.html` - KPI grid with 4 cards
-- **Backend**: `GET /api/status` - Returns system overview metrics
-- **Status**: ✅ FULLY INTEGRATED
-- **Data Flow**:

-**Warning alerts** trigger at **80% usage**.
-
----
-
-## 🗃️ DATABASE MANAGEMENT
-
-### **Database Location:**
-```
-data/api_monitor.db
-```
-
-### **Backup Strategy:**
-
-```bash
-# Manual backup
-cp data/api_monitor.db data/api_monitor_backup_$(date +%Y%m%d).db
-
-# Automated daily backup (add to crontab)
-0 2 * * * cp /home/user/crypto-dt-source/data/api_monitor.db \
-  /home/user/crypto-dt-source/data/backups/api_monitor_$(date +\%Y\%m\%d).db
-
-# Keep last 30 days
-find /home/user/crypto-dt-source/data/backups/ -name "api_monitor_*.db" \
-  -mtime +30 -delete
-```
-
-### **Database Size Expectations:**
-- **Day 1**: ~10-20 MB
-- **Week 1**: ~50-100 MB
-- **Month 1**: ~100-500 MB (depending on data retention)
-
-### **Data Retention:**
-Current configuration retains **all historical data** indefinitely. To implement cleanup:
-
-```python
-# Add to monitoring/scheduler.py
-def cleanup_old_data():
-    """Remove data older than 90 days"""
-    cutoff = datetime.utcnow() - timedelta(days=90)
-
-    # Clean old connection attempts
-    db_manager.delete_old_attempts(cutoff)
-
-    # Clean old system metrics
-    db_manager.delete_old_metrics(cutoff)
-```
-
----
-
-## 🔒 SECURITY BEST PRACTICES
-
-### ✅ **Already Implemented:**
-
-1. **API Keys**: Loaded from environment variables
-2. **Key Masking**: Sensitive data masked in logs
-3. **SQLAlchemy ORM**: Protected against SQL injection
-4. **CORS**: Configured for cross-origin requests
-5. **Input Validation**: Pydantic models for request validation
-
-### ⚠️ **Production Hardening** (Optional but Recommended):
-
-#### **1. Add Authentication** (if exposing to internet):
-
-```bash
-# Install dependencies
-pip install python-jose[cryptography] passlib[bcrypt]
-
-# Implement JWT authentication
-# See: https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/
-```
-
-#### **2. Enable HTTPS**:
-
-```bash
-# Using Let's Encrypt with Nginx reverse proxy
-sudo apt install nginx certbot python3-certbot-nginx
-
-# Configure Nginx
-sudo nano /etc/nginx/sites-available/crypto-hub
-
-# Nginx config:
-server {
-    listen 80;
-    server_name your-domain.com;
-    return 301 https://$server_name$request_uri;
-}
-
-server {
-    listen 443 ssl;
-    server_name your-domain.com;
-
-    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
-    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
-
-    location / {
-        proxy_pass http://localhost:7860;
-        proxy_http_version 1.1;
-        proxy_set_header Upgrade $http_upgrade;
-        proxy_set_header Connection "upgrade";
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-    }
-}
-
-# Enable and test
-sudo ln -s /etc/nginx/sites-available/crypto-hub /etc/nginx/sites-enabled/
-sudo nginx -t
-sudo systemctl restart nginx
-
-# Get certificate
-sudo certbot --nginx -d your-domain.com
-```
-
-#### **3. Firewall Configuration**:
-
-```bash
-# Allow only necessary ports
-sudo ufw allow 22/tcp    # SSH
-sudo ufw allow 80/tcp    # HTTP
-sudo ufw allow 443/tcp   # HTTPS
-sudo ufw enable
-```
-
-#### **4. Rate Limiting** (Prevent abuse):
-
-Add to `app.py`:
-```python
-from slowapi import Limiter, _rate_limit_exceeded_handler
-from slowapi.util import get_remote_address
-
-limiter = Limiter(key_func=get_remote_address)
-app.state.limiter = limiter
-app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
-
-@app.get("/api/status")
-@limiter.limit("10/minute")  # Max 10 requests per minute
-async def get_status(request: Request):
-    ...
-```
-

-
-## 📈 SCALING CONSIDERATIONS
-
-### **Current Capacity:**
-- **Concurrent WebSocket Connections**: 50+ tested
-- **API Requests**: ~500/minute (depending on provider rate limits)
-- **Database**: SQLite handles ~100k records/month efficiently
-
-### **When to Scale:**
-
-#### **Migrate to PostgreSQL** when:
-- Database size > 1 GB
-- Need multiple application instances
-- Require advanced querying/analytics
-
-```bash
-# PostgreSQL setup
-sudo apt install postgresql postgresql-contrib
-
-# Update database/db.py connection string
-DATABASE_URL = "postgresql://user:password@localhost/crypto_hub"
-```
-
-#### **Add Redis Caching** when:
-- Response times > 500ms
-- High read load on database
-- Need distributed rate limiting
-
-```bash
-# Install Redis
-sudo apt install redis-server
-
-# Update config to use Redis for caching
-pip install redis aioredis
-```
-
-#### **Kubernetes Deployment** for:
-- High availability requirements
-- Auto-scaling needs
-- Multi-region deployment
-

-```bash
-# Check recent data collections
-sqlite3 data/api_monitor.db \
-  "SELECT provider_id, category, actual_fetch_time FROM data_collections \
-   ORDER BY actual_fetch_time DESC LIMIT 10;"
-
-# Should show recent timestamps (last 1-15 minutes depending on schedule)
-```
-
-### **5. Scheduler Status:**
-
-```bash
-curl http://localhost:7860/api/schedule | jq
-
-# Check compliance:
-# - on_time_count should be > 0
-# - on_time_percentage should be > 80%
-```
-
----
-
-## 🐛 TROUBLESHOOTING
-
-### **Common Issues:**
-
-#### **1. "Database not found" error:**
-
-```bash

+  "news": {
+    "CryptoPanic": {"staleness_minutes": 8.5, "status": "fresh"}
+  }
+}
+```
+
+---
+
+## 🔧 CONFIGURATION OPTIONS
+
+### **Schedule Intervals** (in `app.py` startup):
+
+```python
+interval_map = {
+    'market_data': 'every_1_min',        # BTC/ETH/BNB prices
+    'blockchain_explorers': 'every_5_min', # Gas prices, network stats
+    'news': 'every_10_min',              # News articles
+    'sentiment': 'every_15_min',         # Fear & Greed Index
+    'onchain_analytics': 'every_5_min',  # On-chain metrics
+    'rpc_nodes': 'every_5_min',          # Block heights
+}
+```
+
+**To modify**:
+1. Edit the interval_map in `app.py` (lines 123-131)
+2. Restart the application
+3. Changes will be reflected in schedule compliance tracking
+
+### **Rate Limits** (in `config.py`):
+
+Each provider has configured rate limits:
+- **CoinGecko**: 50 calls/minute
+- **Etherscan**: 5 calls/second
+- **CoinMarketCap**: 100 calls/hour
+- **NewsAPI**: 200 calls/day
+
+**Warning alerts** trigger at **80% usage**.
+
+---
+
+## 🗃️ DATABASE MANAGEMENT
+
+### **Database Location:**
+```
+data/api_monitor.db
+```
+
+### **Backup Strategy:**
+
+```bash
+# Manual backup
+cp data/api_monitor.db data/api_monitor_backup_$(date +%Y%m%d).db
+
+# Automated daily backup (add to crontab)
+0 2 * * * cp /home/user/crypto-dt-source/data/api_monitor.db \
+  /home/user/crypto-dt-source/data/backups/api_monitor_$(date +\%Y\%m\%d).db
+
+# Keep last 30 days
+find /home/user/crypto-dt-source/data/backups/ -name "api_monitor_*.db" \
+  -mtime +30 -delete
+```
+
+### **Database Size Expectations:**
+- **Day 1**: ~10-20 MB
+- **Week 1**: ~50-100 MB
+- **Month 1**: ~100-500 MB (depending on data retention)
+
+### **Data Retention:**
+Current configuration retains **all historical data** indefinitely. To implement cleanup:
+
+```python
+# Add to monitoring/scheduler.py
+def cleanup_old_data():
+    """Remove data older than 90 days"""
+    cutoff = datetime.utcnow() - timedelta(days=90)
+
+    # Clean old connection attempts
+    db_manager.delete_old_attempts(cutoff)
+
+    # Clean old system metrics
+    db_manager.delete_old_metrics(cutoff)
+```
+
+---
+
+## 🔒 SECURITY BEST PRACTICES
+
+### ✅ **Already Implemented:**
+
+1. **API Keys**: Loaded from environment variables
+2. **Key Masking**: Sensitive data masked in logs
+3. **SQLAlchemy ORM**: Protected against SQL injection
+4. **CORS**: Configured for cross-origin requests
+5. **Input Validation**: Pydantic models for request validation
+
+### ⚠️ **Production Hardening** (Optional but Recommended):
+
+#### **1. Add Authentication** (if exposing to internet):
+
+```bash
+# Install dependencies
+pip install python-jose[cryptography] passlib[bcrypt]
+
+# Implement JWT authentication
+# See: https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/
+```
+
+#### **2. Enable HTTPS**:
+
+```bash
+# Using Let's Encrypt with Nginx reverse proxy
+sudo apt install nginx certbot python3-certbot-nginx
+
+# Configure Nginx
+sudo nano /etc/nginx/sites-available/crypto-hub
+
+# Nginx config:
+server {
+    listen 80;
+    server_name your-domain.com;
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl;
+    server_name your-domain.com;
+
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    location / {
+        proxy_pass http://localhost:7860;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+
+# Enable and test
+sudo ln -s /etc/nginx/sites-available/crypto-hub /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl restart nginx
+
+# Get certificate
+sudo certbot --nginx -d your-domain.com
+```
+
+#### **3. Firewall Configuration**:
+
+```bash
+# Allow only necessary ports
+sudo ufw allow 22/tcp    # SSH
+sudo ufw allow 80/tcp    # HTTP
+sudo ufw allow 443/tcp   # HTTPS
+sudo ufw enable
+```
+
+#### **4. Rate Limiting** (Prevent abuse):
+
+Add to `app.py`:
+```python
+from slowapi import Limiter, _rate_limit_exceeded_handler
+from slowapi.util import get_remote_address
+
+limiter = Limiter(key_func=get_remote_address)
+app.state.limiter = limiter
+app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
+
+@app.get("/api/status")
+@limiter.limit("10/minute")  # Max 10 requests per minute
+async def get_status(request: Request):
+    ...
+```
+
+---
+
+## 📈 SCALING CONSIDERATIONS
+
+### **Current Capacity:**
+- **Concurrent WebSocket Connections**: 50+ tested
+- **API Requests**: ~500/minute (depending on provider rate limits)
+- **Database**: SQLite handles ~100k records/month efficiently
+
+### **When to Scale:**
+
+#### **Migrate to PostgreSQL** when:
+- Database size > 1 GB
+- Need multiple application instances
+- Require advanced querying/analytics
+
+```bash
+# PostgreSQL setup
+sudo apt install postgresql postgresql-contrib
+
+# Update database/db.py connection string
+DATABASE_URL = "postgresql://user:password@localhost/crypto_hub"
+```
+
+#### **Add Redis Caching** when:
+- Response times > 500ms
+- High read load on database
+- Need distributed rate limiting
+
+```bash
+# Install Redis
+sudo apt install redis-server
+
+# Update config to use Redis for caching
+pip install redis aioredis
+```
+
+#### **Kubernetes Deployment** for:
+- High availability requirements
+- Auto-scaling needs
+- Multi-region deployment
+

+npm install -g wscat
+wscat -c ws://localhost:7860/ws/master
+```
+
+### **4. Data Collection Verification:**
+
+```bash
+# Check recent data collections
+sqlite3 data/api_monitor.db \
+  "SELECT provider_id, category, actual_fetch_time FROM data_collections \
+   ORDER BY actual_fetch_time DESC LIMIT 10;"
+
+# Should show recent timestamps (last 1-15 minutes depending on schedule)
+```
+
+### **5. Scheduler Status:**
+
+```bash
+curl http://localhost:7860/api/schedule | jq
+
+# Check compliance:
+# - on_time_count should be > 0

+# Restart application to reload .env
+```
+
+#### **3. High rate limit usage:**
+
+```bash
+# Check current rate limits
+curl http://localhost:7860/api/rate-limits
+
+# If > 80%, reduce schedule frequency in app.py
+# Change 'every_1_min' to 'every_5_min' for example
+```
+
+#### **4. WebSocket connection fails:**
+
+```bash
+# Check if port 7860 is open
+netstat -tuln | grep 7860
+
+# Check CORS settings in app.py
+# Ensure your domain is allowed
+```
+
+#### **5. Slow response times:**
+
+```bash
+# Check database size
+ls -lh data/api_monitor.db
+
+# If > 500MB, implement data cleanup
+# Add retention policy (see Database Management section)
+```

-No new dependencies added. Uses existing:
-- FastAPI (query parameters, routing)
-- SQLAlchemy (database queries)
-- pydantic (validation)
-
-### Reverse Proxy (Optional)
-
-Recommended nginx/cloudflare rate limiting:
-
-```nginx
-# Rate limit chart endpoints
-location /api/charts/ {
-    limit_req zone=charts burst=10 nodelay;
-    limit_req_status 429;
-    proxy_pass http://backend;
-}
-
-# Define rate limit zone (60 req/min per IP)
-limit_req_zone $binary_remote_addr zone=charts:10m rate=60r/m;
-```
-
----
-
-## Monitoring & Alerting
-
-### Recommended Metrics
-
-Add to your monitoring system (Prometheus, Datadog, etc.):
-
-```yaml
-# Response time histogram
-chart_response_time_seconds{endpoint, quantile}
-
-# Request counter
-chart_requests_total{endpoint, status}
-
-# Error rate
-chart_errors_total{endpoint, error_type}
-
-# Provider-specific metrics
-ratelimit_usage_pct{provider}
-freshness_staleness_min{provider}
-```
-
-### Recommended Alerts
-
-```yaml
-# Critical: Rate limit near exhaustion
-- alert: RateLimitCritical
-  expr: ratelimit_usage_pct > 90
-  for: 3h
-
-# Critical: Data stale
-- alert: DataStaleCritical
-  expr: freshness_staleness_min > ttl_min * 2
-  for: 15m
-
-# Warning: Chart endpoint slow
-- alert: ChartEndpointSlow
-  expr: histogram_quantile(0.95, chart_response_time_seconds) > 0.5
-  for: 10m
-```
-
----
-
-## Rollback Plan
-
-If issues arise after deployment:
-
-### Option 1: Feature Flag (Recommended)
-
-```python
-# In api/endpoints.py, wrap endpoints with feature flag
-if config.get("ENABLE_CHART_ENDPOINTS", False):
-    @router.get("/charts/rate-limit-history")
-    async def get_rate_limit_history(...):
-        ...
-```
-
-### Option 2: Git Revert
-
-```bash
-# Revert this PR
-git revert <commit-hash>
-
-# Or cherry-pick revert of specific files
-git checkout <previous-commit> -- api/endpoints.py
-```
-
-### Option 3: Emergency Disable (Nginx)
-
-```nginx
-# Block chart endpoints temporarily
-location /api/charts/ {
-    return 503;
-}
-```
-
----
-
-## Known Limitations
-
-1. **No caching layer** - Each request hits database (acceptable for now)
-2. **Max 5 providers** - Hard limit (by design)
-3. **Max 168 hours** - Hard limit (1 week, by design)
-4. **Hourly granularity** - Not configurable (by design)
-5. **No real-time updates** - Requires polling or WebSocket (future work)
-
----
-

-
-## Additional Notes
-
-### Why This Implementation?
-
-1. **Hourly bucketing** - Balances granularity with performance and data volume
-2. **Max 5 providers** - Prevents chart clutter and ensures good UX
-3. **168 hour limit** - One week is sufficient for most monitoring use cases
-4. **Allow-list validation** - Prevents enumeration and ensures data integrity
-5. **In-memory bucketing** - Faster than complex SQL GROUP BY queries
-6. **Gap filling** - Ensures consistent chart rendering (no missing x-axis points)
-
-### Performance Considerations
-
-- Database queries use indexed columns (timestamp, provider_id)
-- Limited result sets (max 5 providers * 168 hours = 840 points per query)
-- Simple aggregation (max one record per hour per provider)
-- No expensive JOINs or subqueries
-
-### Security Considerations
-
-- No user authentication required (internal monitoring API)
-- Rate limiting recommended at reverse proxy level
-- Input validation prevents common injection attacks
-- Error messages are safe (no stack traces, SQL fragments)
-
----
-
-## Questions for Reviewers
-
-1. Should we add caching at this stage or defer to later PR?
-2. Is 168 hours (1 week) an appropriate max, or should it be configurable?
-3. Should we add authentication/API keys for these endpoints?
-4. Do we want category-level aggregation in this PR or separate?

+- **Branch:** `claude/charts-validation-hardening-011CV1CcAkZk3mmcqPa85ukk`
+
+### Testing Confirmation
+
+- [x] All automated tests pass locally
+- [x] Sanity checks pass locally
+- [x] Manual API testing completed
+- [x] Performance benchmarks met
+- [x] Security review self-assessment completed
+
+---
+
+## Additional Notes
+
+### Why This Implementation?
+
+1. **Hourly bucketing** - Balances granularity with performance and data volume
+2. **Max 5 providers** - Prevents chart clutter and ensures good UX
+3. **168 hour limit** - One week is sufficient for most monitoring use cases
+4. **Allow-list validation** - Prevents enumeration and ensures data integrity
+5. **In-memory bucketing** - Faster than complex SQL GROUP BY queries
+6. **Gap filling** - Ensures consistent chart rendering (no missing x-axis points)
+
+### Performance Considerations
+
+- Database queries use indexed columns (timestamp, provider_id)
+- Limited result sets (max 5 providers * 168 hours = 840 points per query)
+- Simple aggregation (max one record per hour per provider)
+- No expensive JOINs or subqueries
+
+### Security Considerations
+
+- No user authentication required (internal monitoring API)
+- Rate limiting recommended at reverse proxy level
+- Input validation prevents common injection attacks
+- Error messages are safe (no stack traces, SQL fragments)
+
+---
+
+## Questions for Reviewers
+
+1. Should we add caching at this stage or defer to later PR?
+2. Is 168 hours (1 week) an appropriate max, or should it be configurable?
+3. Should we add authentication/API keys for these endpoints?
+4. Do we want category-level aggregation in this PR or separate?

-
-## 📈 Status Classification
-
-The monitor automatically classifies each API into one of five states:
-
-| Status | Success Rate | Response Time | Description |
-|--------|--------------|---------------|-------------|
-| 🟢 **ONLINE** | ≥95% | <2 seconds | Fully operational, optimal performance |
-| 🟡 **DEGRADED** | 80-95% | 2-5 seconds | Functional but slower than normal |
-| 🟠 **SLOW** | 70-80% | 5-10 seconds | Significant performance issues |
-| 🔴 **UNSTABLE** | 50-70% | Any | Frequent failures, unreliable |
-| ⚫ **OFFLINE** | <50% | Any | Not responding or completely down |
-
-**Classification Logic:**
-- Based on last 10 health checks
-- Success rate = successful responses / total attempts
-- Response time = average of successful requests only
-
----
-
-## ⚠️ Alert Conditions
-
-The system triggers alerts for:
-
-### Critical Alerts
-- ❌ TIER-1 API offline (Etherscan, CoinGecko, Infura, Alchemy)
-- ❌ All providers in a category offline
-- ❌ Zero available resources for essential data type
-
-### Warning Alerts

-- ⚠️ Rate limit reached (>80% consumed)
-
-### Info Alerts
-- ℹ️ API key approaching expiration
-- ℹ️ SSL certificate expires within 7 days
-- ℹ️ New resource added to registry
-
----
-
-## 🔄 Failover Management
-
-### Automatic Failover Chains
-
-The system builds intelligent failover chains for each data type:
-
-```javascript
-// Example: Ethereum Price Failover Chain
-const failoverConfig = require('./failover-config.json');
-
-async function getEthereumPrice() {
-  const chain = failoverConfig.chains.ethereumPrice;
-
-  for (const resource of chain) {
-    try {
-      // Try primary first (CoinGecko)
-      const response = await fetch(resource.url + '/api/v3/simple/price?ids=ethereum&vs_currencies=usd');
-      const data = await response.json();
-      return data.ethereum.usd;
-    } catch (error) {
-      console.log(`${resource.name} failed, trying next in chain...`);
-      continue;
-    }
-  }
-
-  throw new Error('All resources in failover chain failed');
-}
-```
-
-### Priority Tiers
-
-**TIER-1 (CRITICAL):** Etherscan, BscScan, CoinGecko, Infura, Alchemy
-**TIER-2 (HIGH):** CoinMarketCap, CryptoCompare, TronScan, NewsAPI
-**TIER-3 (MEDIUM):** Alternative.me, Reddit, CORS proxies, public RPCs
-**TIER-4 (LOW):** Experimental APIs, community nodes, backup sources
-
-Failover chains prioritize lower tier numbers first.

-## 🛠️ Troubleshooting
-
-### "Failed to load registry"
-
-**Cause:** `all_apis_merged_2025.json` not found
-**Solution:** Ensure the file exists in the same directory
-
-### "Request timeout" errors
-
-**Cause:** API endpoint is slow or down
-**Solution:** Normal behavior, will be classified as SLOW/OFFLINE
-
-### "CORS error" in dashboard
-
-**Cause:** Report JSON not accessible
-**Solution:** Run `npm run dashboard` to start local server
-
-### Rate limit errors (429)
-
-**Cause:** Too many requests to API
-**Solution:** Increase `CHECK_INTERVAL` or reduce resource list

+
+## 📈 Status Classification
+
+The monitor automatically classifies each API into one of five states:
+
+| Status | Success Rate | Response Time | Description |
+|--------|--------------|---------------|-------------|
+| 🟢 **ONLINE** | ≥95% | <2 seconds | Fully operational, optimal performance |
+| 🟡 **DEGRADED** | 80-95% | 2-5 seconds | Functional but slower than normal |
+| 🟠 **SLOW** | 70-80% | 5-10 seconds | Significant performance issues |
+| 🔴 **UNSTABLE** | 50-70% | Any | Frequent failures, unreliable |
+| ⚫ **OFFLINE** | <50% | Any | Not responding or completely down |
+
+**Classification Logic:**
+- Based on last 10 health checks
+- Success rate = successful responses / total attempts
+- Response time = average of successful requests only
+
+---
+
+## ⚠️ Alert Conditions
+
+The system triggers alerts for:
+
+### Critical Alerts
+- ❌ TIER-1 API offline (Etherscan, CoinGecko, Infura, Alchemy)
+- ❌ All providers in a category offline
+- ❌ Zero available resources for essential data type
+
+### Warning Alerts
+- ⚠️ Response time >5 seconds sustained for 15 minutes
+- ⚠️ Success rate dropped below 80%
+- ⚠️ Single Point of Failure (only 1 provider available)
+- ⚠️ Rate limit reached (>80% consumed)
+
+### Info Alerts
+- ℹ️ API key approaching expiration
+- ℹ️ SSL certificate expires within 7 days
+- ℹ️ New resource added to registry
+
+---
+
+## 🔄 Failover Management
+
+### Automatic Failover Chains
+
+The system builds intelligent failover chains for each data type:
+
+```javascript
+// Example: Ethereum Price Failover Chain
+const failoverConfig = require('./failover-config.json');
+
+async function getEthereumPrice() {
+  const chain = failoverConfig.chains.ethereumPrice;
+
+  for (const resource of chain) {
+    try {
+      // Try primary first (CoinGecko)
+      const response = await fetch(resource.url + '/api/v3/simple/price?ids=ethereum&vs_currencies=usd');
+      const data = await response.json();
+      return data.ethereum.usd;
+    } catch (error) {
+      console.log(`${resource.name} failed, trying next in chain...`);
+      continue;
+    }
+  }
+
+  throw new Error('All resources in failover chain failed');
+}
+```
+
+### Priority Tiers
+
+**TIER-1 (CRITICAL):** Etherscan, BscScan, CoinGecko, Infura, Alchemy
+**TIER-2 (HIGH):** CoinMarketCap, CryptoCompare, TronScan, NewsAPI
+**TIER-3 (MEDIUM):** Alternative.me, Reddit, CORS proxies, public RPCs
+**TIER-4 (LOW):** Experimental APIs, community nodes, backup sources
+
+Failover chains prioritize lower tier numbers first.

+## 🛠️ Troubleshooting
+
+### "Failed to load registry"
+
+**Cause:** `all_apis_merged_2025.json` not found
+**Solution:** Ensure the file exists in the same directory
+
+### "Request timeout" errors
+
+**Cause:** API endpoint is slow or down
+**Solution:** Normal behavior, will be classified as SLOW/OFFLINE
+
+### "CORS error" in dashboard
+
+**Cause:** Report JSON not accessible
+**Solution:** Run `npm run dashboard` to start local server
+
+### Rate limit errors (429)
+
+**Cause:** Too many requests to API
+**Solution:** Increase `CHECK_INTERVAL` or reduce resource list

+// Check system status
+const status = await aggregator.getStatus();
+console.log(`${status.online}/${status.total_resources} resources online`);
+```
+
+## Monitoring & Maintenance
+
+- Check `/status` regularly to ensure resources are online
+- Monitor `/history/stats` for usage patterns and success rates
+- Review consecutive failures in the database
+- Update API keys when needed
+
+## License
+
+This aggregator is built for educational and development purposes.
+API keys should be kept secure and rate limits respected.
+
+## Support
+
+For issues or questions:
+1. Check the `/health` endpoint
+2. Review `/history` for error patterns
+3. Verify resource status with `/status`
+4. Check individual resource documentation

-## Overview
-
-The Crypto API Monitoring System provides comprehensive WebSocket APIs for real-time streaming of all services. All WebSocket endpoints support:
-
-- **Subscription-based routing**: Subscribe only to services you need
-- **Real-time updates**: Live data streaming at service-specific intervals
-- **Bi-directional communication**: Send commands and receive responses
-- **Connection management**: Automatic reconnection and heartbeat
-- **Multiple connection patterns**: Master endpoint, service-specific endpoints, or auto-subscribe
-
----
-
-## Quick Start
-
-### Basic Connection
-
-```javascript
-// Connect to the master endpoint
-const ws = new WebSocket('ws://localhost:7860/ws/master');
-
-ws.onopen = () => {
-    console.log('Connected!');
-
-    // Subscribe to market data
-    ws.send(JSON.stringify({
-        action: 'subscribe',
-        service: 'market_data'
-    }));
-};
-
-ws.onmessage = (event) => {
-    const message = JSON.parse(event.data);
-    console.log('Received:', message);
-};
-```
-
-### Python Example
-
-```python
-import asyncio
-import websockets
-import json
-
-async def connect():
-    uri = "ws://localhost:7860/ws/master"
-    async with websockets.connect(uri) as websocket:
-        # Subscribe to whale tracking
-        await websocket.send(json.dumps({
-            "action": "subscribe",
-            "service": "whale_tracking"
-        }))
-
-        # Receive messages
-        async for message in websocket:
-            data = json.loads(message)
-            print(f"Received: {data}")
-
-asyncio.run(connect())
-```

-## Error Handling
-
-### Connection Errors
-
-If a connection fails or is lost, implement exponential backoff:
-
-```javascript
-class ReconnectingWebSocket {
-    constructor(url) {
-        this.url = url;
-        this.reconnectDelay = 1000;
-        this.maxReconnectDelay = 30000;
-        this.connect();
-    }
-
-    connect() {
-        this.ws = new WebSocket(this.url);
-
-        this.ws.onclose = () => {
-            console.log(`Reconnecting in ${this.reconnectDelay}ms...`);
-            setTimeout(() => {
-                this.reconnectDelay = Math.min(
-                    this.reconnectDelay * 2,
-                    this.maxReconnectDelay
-                );
-                this.connect();
-            }, this.reconnectDelay);
-        };
-
-        this.ws.onopen = () => {
-            console.log('Connected');
-            this.reconnectDelay = 1000; // Reset delay on successful connection
-        };
-    }
-}
-```
-
-### Message Errors
-
-Handle error messages from the server:
-
-```javascript
-ws.onmessage = (event) => {
-    const message = JSON.parse(event.data);
-
-    if (message.type === 'error') {
-        console.error('Server error:', message.data.message);
-
-        // Handle specific errors
-        if (message.data.message.includes('Invalid service')) {
-            console.log('Available services:', message.data.available_services);
-        }
-    }
-};
-```
-
----
-
-## Best Practices
-
-1. **Subscribe Only to What You Need**: Minimize bandwidth by subscribing only to required services
-2. **Implement Reconnection Logic**: Handle network interruptions gracefully
-3. **Use Heartbeats**: Implement ping/pong to detect connection issues early
-4. **Handle Backpressure**: Process messages efficiently to avoid queue buildup
-5. **Clean Up Subscriptions**: Unsubscribe when components unmount or services are no longer needed
-6. **Use Service-Specific Endpoints**: For single-service needs, use dedicated endpoints to reduce initial setup
-7. **Monitor Connection Status**: Track connection state and subscriptions in your application
-8. **Implement Error Boundaries**: Gracefully handle and display connection/data errors

+
+## Overview
+
+The Crypto API Monitoring System provides comprehensive WebSocket APIs for real-time streaming of all services. All WebSocket endpoints support:
+
+- **Subscription-based routing**: Subscribe only to services you need
+- **Real-time updates**: Live data streaming at service-specific intervals
+- **Bi-directional communication**: Send commands and receive responses
+- **Connection management**: Automatic reconnection and heartbeat
+- **Multiple connection patterns**: Master endpoint, service-specific endpoints, or auto-subscribe
+
+---
+
+## Quick Start
+
+### Basic Connection
+
+```javascript
+// Connect to the master endpoint
+const ws = new WebSocket('ws://localhost:7860/ws/master');
+
+ws.onopen = () => {
+    console.log('Connected!');
+
+    // Subscribe to market data
+    ws.send(JSON.stringify({
+        action: 'subscribe',
+        service: 'market_data'
+    }));
+};
+
+ws.onmessage = (event) => {
+    const message = JSON.parse(event.data);
+    console.log('Received:', message);
+};
+```
+
+### Python Example
+
+```python
+import asyncio
+import websockets
+import json
+
+async def connect():
+    uri = "ws://localhost:7860/ws/master"
+    async with websockets.connect(uri) as websocket:
+        # Subscribe to whale tracking
+        await websocket.send(json.dumps({
+            "action": "subscribe",
+            "service": "whale_tracking"
+        }))
+
+        # Receive messages
+        async for message in websocket:
+            data = json.loads(message)
+            print(f"Received: {data}")
+
+asyncio.run(connect())
+```

+                    this.reconnectDelay * 2,
+                    this.maxReconnectDelay
+                );
+                this.connect();
+            }, this.reconnectDelay);
+        };
+
+        this.ws.onopen = () => {
+            console.log('Connected');
+            this.reconnectDelay = 1000; // Reset delay on successful connection
+        };
+    }
+}
+```
+
+### Message Errors
+
+Handle error messages from the server:
+
+```javascript
+ws.onmessage = (event) => {
+    const message = JSON.parse(event.data);
+
+    if (message.type === 'error') {
+        console.error('Server error:', message.data.message);
+
+        // Handle specific errors
+        if (message.data.message.includes('Invalid service')) {
+            console.log('Available services:', message.data.available_services);
+        }
+    }
+};
+```
+
+---
+
+## Best Practices
+
+1. **Subscribe Only to What You Need**: Minimize bandwidth by subscribing only to required services
+2. **Implement Reconnection Logic**: Handle network interruptions gracefully
+3. **Use Heartbeats**: Implement ping/pong to detect connection issues early
+4. **Handle Backpressure**: Process messages efficiently to avoid queue buildup
+5. **Clean Up Subscriptions**: Unsubscribe when components unmount or services are no longer needed
+6. **Use Service-Specific Endpoints**: For single-service needs, use dedicated endpoints to reduce initial setup
+7. **Monitor Connection Status**: Track connection state and subscriptions in your application
+8. **Implement Error Boundaries**: Gracefully handle and display connection/data errors

-## Dependencies
-
-All required packages are in `requirements.txt`:
-- fastapi
-- uvicorn[standard]
-- websockets
-- sqlalchemy
-- apscheduler
-- aiohttp
-- python-dotenv
-
-## Security Considerations
-
-1. **CORS**: Currently set to allow all origins. In production, specify allowed origins:
-   ```python
-   allow_origins=["https://yourdomain.com"]
-   ```
-
-2. **API Keys**: Masked in responses using `_mask_key()` method
-
-3. **Rate Limiting**: Built-in per-provider rate limiting
-
-4. **WebSocket Authentication**: Can be added by implementing token validation in connection handler
-
-5. **Database**: SQLite is suitable for development. Consider PostgreSQL for production.
-
-## Monitoring & Observability
-
-- **Logs**: Comprehensive logging via `utils.logger`
-- **Health Checks**: `/health` endpoint with component status
-- **Metrics**: System metrics tracked in database
-- **Alerts**: Built-in alerting system
-- **WebSocket Stats**: `/ws/stats` endpoint
-
-## Next Steps (Optional Enhancements)
-
-1. Add WebSocket authentication
-2. Implement topic-based subscriptions
-3. Add message queuing (Redis/RabbitMQ)
-4. Implement horizontal scaling
-5. Add Prometheus metrics export
-6. Implement rate limiting per WebSocket client
-7. Add message replay capability
-8. Implement WebSocket reconnection logic
-9. Add GraphQL API support
-10. Implement API versioning
-
-## Troubleshooting
-
-### WebSocket won't connect:
-- Check firewall settings
-- Verify port 7860 is accessible
-- Check CORS configuration
-
-### Database errors:
-- Ensure `data/` directory exists
-- Check file permissions
-- Verify SQLite is installed
-
-### Scheduler not starting:
-- Check database initialization
-- Verify provider configurations
-- Check logs for errors
-
-### High memory usage:
-- Limit number of WebSocket connections
-- Implement connection pooling
-- Adjust database cleanup settings

+## Dependencies
+
+All required packages are in `requirements.txt`:
+- fastapi
+- uvicorn[standard]
+- websockets
+- sqlalchemy
+- apscheduler
+- aiohttp
+- python-dotenv
+
+## Security Considerations
+
+1. **CORS**: Currently set to allow all origins. In production, specify allowed origins:
+   ```python
+   allow_origins=["https://yourdomain.com"]
+   ```
+
+2. **API Keys**: Masked in responses using `_mask_key()` method
+
+3. **Rate Limiting**: Built-in per-provider rate limiting
+
+4. **WebSocket Authentication**: Can be added by implementing token validation in connection handler
+
+5. **Database**: SQLite is suitable for development. Consider PostgreSQL for production.
+
+## Monitoring & Observability
+
+- **Logs**: Comprehensive logging via `utils.logger`
+- **Health Checks**: `/health` endpoint with component status
+- **Metrics**: System metrics tracked in database
+- **Alerts**: Built-in alerting system
+- **WebSocket Stats**: `/ws/stats` endpoint
+
+## Next Steps (Optional Enhancements)
+
+1. Add WebSocket authentication
+2. Implement topic-based subscriptions
+3. Add message queuing (Redis/RabbitMQ)
+4. Implement horizontal scaling
+5. Add Prometheus metrics export
+6. Implement rate limiting per WebSocket client
+7. Add message replay capability
+8. Implement WebSocket reconnection logic
+9. Add GraphQL API support
+10. Implement API versioning
+
+## Troubleshooting
+
+### WebSocket won't connect:
+- Check firewall settings
+- Verify port 7860 is accessible
+- Check CORS configuration
+
+### Database errors:
+- Ensure `data/` directory exists
+- Check file permissions
+- Verify SQLite is installed
+
+### Scheduler not starting:
+- Check database initialization
+- Verify provider configurations
+- Check logs for errors
+
+### High memory usage:
+- Limit number of WebSocket connections
+- Implement connection pooling
+- Adjust database cleanup settings
+

+
+**Implementation Date**: 2025-11-11
+**Version**: 2.0.0
+**Status**: Production Ready ✅
