This module provides direct REST API integrations for:
- Blockchain data (Etherscan, BscScan, TronScan)
- Market data (CoinMarketCap)
- News aggregation (NewsAPI)
- AI sentiment analysis (HuggingFace models)

All providers use async HTTP with httpx, 10-second timeouts,
and optional 30-second in-memory caching.
