Alternatively paste a base64 PAYMENT-REQUIRED header to lint offline, or a PAYMENT-SIGNATURE payload to check the client side: EIP-3009 authorization completeness, expired validBefore, payTo/value mismatches, and whether the server's advertised extensions were echoed back — the silent omission that makes the facilitator settle happily while Bazaar never indexes the resource.
