What it does

The Blockscout API reads blocks, addresses, tokens and transactions on Ethereum and other EVM chains, for example to show a wallet's token transfers. It has REST, JSON-RPC and GraphQL endpoints with JSON answers. Free with a free API key. An official MCP server at https://mcp.blockscout.com/mcp lets AI agents read chain data.
