x402 endpoint validator: Lint any x402 paid endpoint like a client would: 402 status, PAYMENT-REQUIRED header decode, CAIP-2 network, integer amount, payTo/asset, EIP-712 domain extra, CORS expose headers, bazaar discovery, /.well-known/x402. Score + fixes. Unpaid request only.

How to pay
Call an endpoint, read the price in the 402 answer, and pay from your own wallet with any x402 client on Base. The payment goes straight to the provider: Autonomo lists this API but isn't part of the payment. See The x402 directory.
Paid endpoints
6 endpoints, sorted by usage. Prices are per request.
| Endpoint | Price | Network | Facilitator | Calls / 30d |
