Agent Cafe

● down api-examples

Test and certify your x402 agent - a live mainnet endpoint that grades the *client*, not the seller: point your paying agent at it, it pays real USDC on Base, and you get back a public certificate plus a README badge of exactly what it did. Includes a scam-resistance test (does your agent refuse a deliberately over-priced order?). Free machine-readable menu at [/inspect](https://api.402.coffee/inspect).
