Turns any HTTP API into a pay-per-call service using USDC and ERC-2612 permits. You sign once for 90 days with a daily spend cap, then your agent can call paid APIs without further prompts. Includes 8 free demo services like Wikipedia and currency conversion to test without signup. Sellers can monetize their own MCP servers with a 3-line SDK wrapper, setting per-call prices as low as $0.001. USDC settles directly between your wallet and the API provider with no custodial middleman. Built on Base for sub-cent transaction costs. Useful when you want agents to access premium APIs autonomously without leaking API keys or risking runaway spend.
