APIMesh

20 x402-payable API tools for AI agents. Pay per call with USDC on Base.

What is this?

APIMesh is a collection of web analysis APIs designed for AI agents. Every endpoint uses the x402 payment protocol — agents pay per call with USDC on Base (no API keys, no subscriptions, no accounts).

Most tools have free /preview endpoints so agents can verify the API works before paying.

How x402 Works

1. Agent sends a request to any paid endpoint
2. Server returns 402 Payment Required with payment details (price, wallet, network)
3. Agent signs a USDC payment on Base and includes it in the X-PAYMENT header
4. Server verifies payment via Coinbase CDP facilitator and returns the response

No API keys. No accounts. No subscriptions. Just pay and use.
