Blocksize Agentic Market Intelligence

jf-cmyk/agentic-payments

This connects Claude to Blocksize's financial market data APIs, giving you programmatic access to crypto and traditional market pricing, historical data, and documentation. You'd reach for this when building trading analysis tools, portfolio trackers, or any application that needs real-time or historical market information without manually fetching from multiple data sources. The server runs over streamable HTTP, so you can integrate it remotely without local setup. Useful if you're prototyping fintech features and want Claude to pull current prices, compare assets, or explain market data structures on the fly.
