Summary
Pulls real-time cryptocurrency data including current prices, 24-hour price changes, market cap, and trading volume. Built on the x402 micropayment protocol, so you're paying per API call rather than dealing with subscription tiers or rate limits. Reach for this when you need fresh token data in your Claude workflows without managing API keys or worrying about hitting free tier caps. The SSE transport means you can stream updates, though the sparse GitHub repo doesn't reveal which specific exchanges or data providers it taps. If you're building crypto dashboards, price alerts, or market analysis tools and want usage-based pricing, this handles the data fetching piece.
