Summary
This connects Claude to Blockchair's multi-chain block explorer API, covering Bitcoin, Ethereum, Litecoin, Dogecoin, Monero, and a dozen other chains. You get five tools: pull chain-wide stats, query blocks by hash or height, look up transaction details, check address balances with recent activity, and inspect node software status. It runs through Pipeworx's gateway with no API key required on the free tier. Useful when you need to inspect on-chain data across multiple blockchains without managing separate explorer APIs or authentication. The gateway also supports plain English queries through ask_pipeworx if you want to skip manual tool calls.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
