How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
A JSON object containing the SKU identifier ('passportstamp'), a diagnostic note, the price ('$0.15'), and a title ('Passport Stamp'). If payment is not attached, returns HTTP 402 with eip3009 payment-required details including facilitator and payment channel information.
Example use cases
Testing x402 client payment integration
“I just wired up my x402 client — can you hit the passport stamp endpoint and confirm it successfully pays $0.15 USDC and gets back a valid diagnostic response?”
Debugging 402 response with eip3009 extras
“My app is throwing errors on x402 paywalls — can you probe the passportstamp SKU endpoint and show me what the HTTP 402 response with eip3009 extras looks like when the payment isn't attached?”
Verifying OpenX402 facilitator connectivity
“I need to confirm that OpenX402 is working as my facilitator — can you call the passport stamp diagnostic and verify the settlement goes through correctly for $0.15 USDC?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/passportstamp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, real-money x402 micropayment integration test using the OpenX402 facilitator with eip3009 authorization. It is the right choice for verifying that an x402 client stack — including payment header construction, USDC authorization, and 402-response parsing — works correctly end-to-end. Not suitable for production data retrieval or non-diagnostic use cases.
Side effects
- HTTP 402 returned if no valid eip3009 payment authorization is included in the request
- Payment authorization expired or invalid — eip3009 token rejected by OpenX402 facilitator
- Insufficient USDC balance to cover the $0.15 per-call fee
- Facilitator unavailable — OpenX402 service unreachable, causing settlement failure
- Malformed request properties parameter causes 400 or unexpected response
