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 identifier ('softfail3'), a diagnostic note, the price ('$0.02'), and a title ('Soft Fail 3'). If payment is not provided, returns HTTP 402 with x402 and EIP-3009 extras in the response headers/body, which can be used to initiate the payment flow.
Example use cases
Validate x402 payment gating behavior
“I'm building an x402-enabled API and want to confirm that my endpoint correctly returns a 402 with EIP-3009 extras when a request arrives without payment — can you run the softfail3 diagnostic to verify the flow?”
Test OpenX402 facilitator integration
“Can you probe the x402 softfail3 SKU through OpenX402 and tell me if the facilitator is correctly processing $0.02 USDC payments and returning the expected diagnostic JSON?”
Debug x402 agent payment pipeline
“My AI agent is supposed to auto-pay x402 endpoints using EIP-3009 — can you run the softfail3 diagnostic test to confirm the full payment-then-response cycle works and shows the correct sku, price, and title fields?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/softfail3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or validate x402 payment protocol integration, specifically the soft-fail behavior where an unpaid request returns HTTP 402 with EIP-3009 metadata. Prefer this over other x402 diagnostic SKUs when you want to verify the complete paid/unpaid request cycle at a low cost ($0.02 USDC) using the OpenX402 facilitator specifically.
Side effects
- HTTP 402 returned when no valid x402 payment header is present — expected behavior for unpaid requests
- Payment rejected if facilitator other than OpenX402 is used
- Malformed EIP-3009 authorization causes payment verification failure
- Network timeout or service unavailability returns 5xx
- Invalid or missing properties parameter may yield unexpected response shape
