HOW IT WORKS

HTTP is the checkout.

Request

Call a protected route. The server responds with HTTP 402 and exact Base payment terms.

Pay

Your x402 client signs the USDC authorization. The production facilitator verifies and settles it.

Receive

The same request is completed and a payment receipt is returned with the result.
