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 name ('stubshare41'), a descriptive note confirming this is an example paid shape, the price ('$0.02'), and the title ('Stub Share 41'). On unpaid requests, returns HTTP 402 with EIP-3009 payment extras specifying how to authorize payment.
Example use cases
x402 client integration smoke test
“Hit the x402 stubshare41 diagnostic stub and confirm I get back a valid paid JSON response — I want to make sure my EIP-3009 payment headers are being accepted by OpenX402 before wiring them into my real service.”
Debugging HTTP 402 response format
“Can you call the x402 stubshare41 endpoint without payment and show me the exact HTTP 402 response with the EIP-3009 extras? I need to see what a rejected unpaid request looks like so I can handle it in my app.”
Verifying OpenX402 facilitator is live
“Check if the OpenX402 facilitator is working right now by probing the stubshare41 SKU endpoint — I just need to confirm a $0.02 USDC payment goes through and I get the stub JSON back.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/stubshare41?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or debug an x402 micropayment integration end-to-end, specifically targeting the OpenX402 facilitator with EIP-3009 authorization. It is a known stub with predictable output, making it ideal for smoke tests, CI checks, and client library validation. Prefer this over live production endpoints when you only need to confirm payment flow mechanics rather than real data.
Side effects
- HTTP 402 returned if no valid EIP-3009 payment authorization is included — response includes payment requirement extras
- Payment authorization invalid or expired — facilitator rejects and returns 402
- OpenX402 facilitator unreachable — connection timeout or 503
- Malformed properties parameter — may return 400 or unexpected response
- Insufficient USDC balance — payment cannot be processed by facilitator
