402 comes back with a PAYMENT-REQUIRED header: base64 JSON, accepts[0] = {scheme, network, asset, amount, payTo}, the same object plus license as the body.
Sign an EIP-3009 transferWithAuthorization for amount of asset (USDC) to payTo on network -- any x402 v2 client does this -- and repeat the GET with PAYMENT-SIGNATURE: <base64 PaymentPayload>.
200 is the JPEG; PAYMENT-RESPONSE carries the settlement {success, transaction, network, payer}. 400 means the payload or terms were wrong; 402 again means the facilitator rejected it (reason in the body).
