GET the URL: the 402 answer carries the terms for every network in its PAYMENT-REQUIRED header; the client picks one it holds USDC on, signs a USDC transfer authorization and retries with a PAYMENT-SIGNATURE header. The facilitator pays the gas. The x402 clients cap one payment at 1 USD by default; raise maxAmountPerPayment to pay more.",
