Summary
Connects Claude to Alchemy's Ethereum and Layer 2 APIs through Pipeworx's gateway infrastructure. You get eight focused tools covering the essentials: ERC-20 token balances and allowances, NFT ownership and metadata queries, collection enumeration, and enhanced asset transfer tracking. Also includes a generic JSON-RPC passthrough for anything else you need to call. Useful when you're building workflows that need to read on-chain state, check wallet holdings, or pull NFT data without writing your own RPC client. Runs as a hosted service, so no API key juggling required. Part of Pipeworx's broader gateway that bundles 673+ data sources if you need more than just Ethereum data.
