2. Without payment you receive `402 Payment Required` with an `accepts` array:
   scheme `exact`, network `base-sepolia`, asset USDC
   (`0x036CbD53842c5426634e7929541eC2318f3dCF7e`), `payTo` 0x1a6f8be821d047fcf4dc1bd5c66aa00000000001 and
   `maxAmountRequired` in USDC base units (6 decimals).
3. Transfer the exact USDC amount to `payTo` on Base Sepolia.
4. Retry the same request with header
   `X-PAYMENT: base64({"txHash":"0x...","from":"0x..."})`.
5. On verification you receive `200` with a fulfillment receipt and the order id.
