How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU name ('bazaarecho'), a diagnostic note confirming the shape of a paid response, the price ($0.03), and a title ('Bazaar Echo'). This confirms that the x402 payment was accepted, the EIP-3009 authorization was valid, and the OpenX402 facilitator processed the transaction successfully.
Example use cases
Verify x402 payment pipeline before launch
“Before I go live, can you run a paid diagnostic echo check against my API origin using a GET request to confirm that x402 payments and EIP-3009 authorization are flowing correctly through OpenX402?”
Debug a failing 402 payment response
“My integration keeps getting HTTP 402 errors even after payment — can you probe my endpoint URL with a GET request using the x402 diagnostics tool to see what the EIP-3009 extras look like and whether OpenX402 is processing it right?”
Confirm x402 facilitator readiness for agent wallet
“I'm setting up an AI agent with a crypto wallet to call paid APIs — can you do a test GET probe against a known public 402 URL using the Bazaar Echo diagnostic to verify the x402 flow works before wiring up my agent?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/bazaarecho?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that an x402 payment integration is functioning correctly end-to-end, particularly when using OpenX402 as the facilitator and EIP-3009 authorization. It is the right choice for developers or AI agents that need a real paid diagnostic call to confirm wallet setup, payment header construction, and facilitator connectivity before deploying to production. Prefer it over manual curl tests or mock responses when you need proof that a live $0.03 USDC charge was accepted and echoed back correctly.
Side effects
- HTTP 402 returned with EIP-3009 extras when payment is not included or invalid — request must include a valid x402 payment header
- Unrecognized facilitator — only OpenX402 is supported; other facilitators will be rejected
- Invalid HTTP method — only GET, HEAD, and DELETE are accepted; POST or PUT will fail
- Malformed input object — 'type' must be 'http' and 'method' must be one of the allowed enum values
- Target URL unreachable — if a custom url/origin is provided and it is not publicly accessible, the probe may fail
