Summary
Pulls crypto news from CoinGecko and CryptoPanic with sentiment analysis and token mentions baked in. Runs on the x402 network (USDC-based API access model), so you're paying per call rather than running your own scraper. Connects via SSE transport to a remote endpoint at crypto-news.api.klymax402.com. Useful when you need an AI agent to stay current on crypto events or gauge market sentiment without building your own news aggregation pipeline. The source repo is light on implementation details, but the integration is straightforward: point Claude at real-time crypto news data with sentiment scores already attached.
