25 x402 paid API tools for AI agents on Base mainnet.
25 pay-per-call API tools for AI agents, powered by the x402 protocol on Base mainnet.
This MCP server exposes 25 paid API endpoints as MCP tools. When an AI agent (Claude, Cursor, Cline) calls a tool, the request goes to our x402 server. The first request returns HTTP 402 (Payment Required). The agent's x402 client pays in USDC on Base mainnet and retries for the result.
No API keys. No signup. Payment IS the authentication.
