Primary production API: extract schema-valid JSON with x402 V2.
Always paid from the first call. Send the JSON body, decode the PAYMENT-REQUIRED response header, sign the live terms, and retry the identical request with PAYMENT-SIGNATURE. The server verifies first and settles only after producing a successful schema-valid response. Trust the live challenge for the price, asset, payee, and resource rather than hardcoding payment terms.
