How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
On unpaid requests: an HTTP 402 response body containing EIP-3009 payment extras and payment requirements enforced by the OpenX402 facilitator. On paid requests (with valid x402 payment): diagnostic screening results for the submitted HTTP request type and method.
Example use cases
Testing x402 payment gating integration
“I'm building an x402-enabled app and want to verify that unpaid GET requests correctly get back a 402 response with EIP-3009 payment details — can you hit the x402 screener endpoint and show me the payment challenge it returns?”
Debugging EIP-3009 payment headers
“My x402 client isn't parsing the payment extras correctly. Can you make an unpaid GET request to the x402 screener and show me the exact EIP-3009 fields returned in the 402 response so I can debug my parser?”
Validating OpenX402 facilitator behavior
“I need to confirm the OpenX402 facilitator is correctly enforcing payment gating. Run a screener probe using a GET method and tell me whether the 402 challenge and payment requirements look correct.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/screener?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test, diagnose, or validate x402 micropayment protocol flows — specifically to inspect real 402 responses with EIP-3009 extras from the OpenX402 facilitator. Ideal for developers building or debugging x402-compatible clients, wallets, or payment agents that need a live reference endpoint for payment challenge inspection.
Side effects
- Unpaid request returns HTTP 402 with EIP-3009 payment challenge — expected behavior, not an error
- Invalid or missing 'type' or 'method' fields in input cause request rejection
- Unsupported method values (outside GET/HEAD/DELETE/POST enum) result in validation error
- OpenX402 facilitator unavailable causes payment verification failure
- Malformed payment token leads to 402 re-challenge
