How x402 payment works

1.Your agent requests a paid endpoint. Server responds with 402 Payment Required and payment terms in the PAYMENT-REQUIRED header.

2.Agent signs a USDC payment payload on Base and retries the request with a PAYMENT-SIGNATURE header.

3.The facilitator verifies the signature. Settlement onchain only happens if the request succeeds (2xx response) — failed lookups don't charge.

4.Server returns 200 OK with the data and a PAYMENT-RESPONSE header containing the transaction hash.

Most agent frameworks handle this flow automatically. See the x402 SDK for client libraries in TypeScript, Python, and Go. This API is registered via the Bazaar discovery layer.
