Connects Claude to Crypto APIs for querying blockchain address balances and transactions across 15+ chains without requiring address sync. You get tools for EVM chains (Ethereum, BSC, Polygon, Base, etc.), UTXO chains (Bitcoin, Litecoin, Dogecoin), plus Solana, XRP, and Kaspa. Each tool exposes actions like get balance, list transactions, and list token transfers with cursor based pagination for the last 14 days of data. Works in stdio mode for Claude Desktop or HTTP mode for n8n workflows. Requires a Crypto APIs account and API key. Good when you need real time blockchain data without running your own nodes or managing address synchronization infrastructure.
