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 ('contactcard'), a descriptive note, the price ('$0.18'), and a title ('Contact Card'). Without valid x402 payment, the endpoint returns HTTP 402 with EIP-3009 payment extras. After payment via OpenX402 facilitator, the full contact card payload is returned.
Example use cases
Testing x402 payment integration
“I'm building an x402-gated API and want to see a real working example — can you call the OpenClaw contact card endpoint, pay the $0.18 USDC, and show me the full response so I can compare it to my own implementation?”
Retrieving OpenClaw contact details
“Can you get the contact card for OpenClaw Productions? It's behind a micropayment wall — go ahead and pay the $0.18 USDC using x402 and bring back whatever contact info it returns.”
Diagnosing EIP-3009 payment flow
“I need to verify that eip3009 payment authorization works end-to-end — please hit the OpenClaw contact card endpoint without paying first so I can see the HTTP 402 error, then pay and confirm the successful response.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/contactcard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or demonstrate an end-to-end x402 micropayment flow using a real, live paid SKU gated by the OpenX402 facilitator. It is particularly useful for developers validating EIP-3009 payment authorization, debugging HTTP 402 response handling, or retrieving actual contact information for OpenClaw Productions after paying $0.18 USDC.
Side effects
- HTTP 402 returned when no x402 payment header is present, with EIP-3009 payment requirement details in the response body
- Payment rejected by OpenX402 facilitator if the payment token is invalid or expired
- Incorrect facilitator used — only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties parameter may result in a 400 error
- Endpoint may be unavailable if OpenClaw Productions server is down
