How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU name ('hookproofpack'), a diagnostic note confirming it is a paid response shape, the price ('$0.22'), and the product title ('Hook Proof Pack'). If payment is not provided, returns HTTP 402 with EIP-3009 payment challenge extras.
Example use cases
Validate x402 client payment integration
“I just built an x402 payment client and want to make sure it correctly submits EIP-3009 authorization and gets back a paid response — can you run the Hook Proof Pack diagnostic to confirm the full flow works?”
Inspect 402 challenge before paying
“Hit the Hook Proof Pack endpoint without paying first so I can see exactly what the HTTP 402 response and EIP-3009 extras look like — I want to understand the challenge structure before wiring up my payment logic.”
Confirm OpenX402 facilitator connectivity
“Can you test the Hook Proof Pack SKU through OpenX402 to verify that the facilitator is reachable and correctly gatekeeping the $0.22 USDC paid response?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/hookproofpack?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or validate an x402 HTTP payment protocol integration end-to-end, specifically with the OpenX402 facilitator and EIP-3009 USDC micropayments. It is the right choice when you want a real paid API response to confirm your client correctly handles payment gating, challenge parsing, and settlement — not for general content delivery or data retrieval.
Side effects
- HTTP 402 returned when no valid x402 payment authorization header is present, along with EIP-3009 payment challenge details
- Payment rejected if the USDC transfer amount does not match the $0.22 required price
- Facilitator error if OpenX402 is unavailable or the payment cannot be settled
- Invalid or malformed EIP-3009 signature causes payment verification failure
- Request may fail if the properties input parameter is malformed
