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 ('scopevoucher'), a diagnostic note, the price ($0.18), and a title ('Scope Voucher'), confirming successful payment processing through the x402 protocol and OpenX402 facilitator.
Example use cases
Testing x402 payment gate integration
“Can you hit the x402 scope voucher endpoint and confirm that when I send a valid $0.18 USDC payment via EIP-3009, I get back the paid diagnostic JSON and not a 402 error?”
Debugging 402 rejection without payment
“I want to verify that the OpenX402 scope voucher endpoint correctly returns an HTTP 402 with EIP-3009 extras when I make a request without attaching a payment — can you test that for me?”
Validating OpenX402 facilitator setup
“Check whether my OpenX402 facilitator integration is working properly by calling the scope voucher diagnostic and confirming the SKU, price, and title fields all come back in the response.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/scopevoucher?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or demonstrate the x402 HTTP payment protocol with EIP-3009/USDC micropayments, specifically against the OpenX402 facilitator. It is the right choice for developers validating their x402 client implementation, confirming payment gating behavior, or debugging 402 responses in a controlled diagnostic context.
Side effects
- HTTP 402 returned with EIP-3009 payment details if no valid payment is attached
- Invalid or malformed EIP-3009 signature results in payment rejection
- OpenX402 facilitator unavailable causes endpoint to be unreachable
- Incorrect USDC amount causes payment validation failure
- Request without required payment header returns 402 before any content is served
