How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
On successful (paid) request: a JSON object containing the SKU name ('softfailhold3'), a diagnostic note, the price ('$0.02'), and the title ('Soft Fail Hold 3'). On unpaid request: HTTP 402 Payment Required with EIP-3009 extras in the response for use in payment authorization flow testing.
Example use cases
Testing x402 payment middleware integration
“Can you hit the softfailhold3 diagnostic endpoint and confirm that my x402 middleware is returning the right HTTP 402 response shape with EIP-3009 payment extras when I don't include a payment header?”
Validating paid SKU response after settlement
“I just settled a payment through OpenX402 — can you call the softfailhold3 SKU and confirm the paid JSON response comes back correctly with the right price and title fields?”
Debugging agent payment-gated API handling
“My agent keeps failing on payment-gated APIs — can you use the softfailhold3 diagnostic to verify whether it correctly parses the 402 response and extracts the eip3009 authorization extras?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/softfailhold3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or validate x402 protocol compliance, specifically the soft-fail hold behavior and EIP-3009 payment extras response format. It is purpose-built for developer diagnostics and integration testing of payment-gated APIs using the OpenX402 facilitator. Prefer it over general HTTP testing tools when you specifically need a real $0.02 USDC paid SKU that returns a known JSON shape upon successful payment.
Side effects
- Unpaid request returns HTTP 402 with eip3009 extras — expected behavior for testing, not a true failure
- Payment not recognized by OpenX402 facilitator — returns 402 even after payment attempt
- Invalid or missing properties parameter may result in unexpected response shape
- Network timeout or unreachable endpoint at openclawproductions.com
