x402search is a pay-per-search MCP server that lets AI agents discover 14,000+ x402-enabled HTTP APIs. Each search costs $0.01 USDC on Base mainnet. It requires an EVM private key and USDC balance but no account registration.

How to use x402search?

Install via npm or pip, then configure the MCP client with your EVM private key. For Claude Desktop, add the server to claude_desktop_config.json.
