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 ('listlag'), a diagnostic note, the price ('$0.02'), and a title ('List Lag') confirming the paid endpoint responded correctly. Unpaid requests return HTTP 402 with EIP-3009 payment extras instead.
Example use cases
Verify x402 payment gate health
“Can you run the listlag x402 diagnostic on https://openclawproductions.com to confirm the paid micropayment SKU is returning the correct HTTP 402 with EIP-3009 extras?”
Debug x402 integration for new origin
“I just set up x402 on https://myapp.example.com — can you probe it with a GET listlag diagnostic to see if the payment gate is configured right?”
Confirm OpenX402 facilitator connectivity
“Check that the OpenX402 facilitator is properly handling the listlag SKU for my origin https://openclawproductions.com and show me the diagnostic response.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/listlag?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402 micropayment gate is correctly configured and responding with EIP-3009 payment data on a specific origin. It is specifically suited for developers and agents testing x402 protocol compliance, debugging 402 payment flows, or confirming OpenX402 facilitator connectivity — not for general web diagnostics or non-x402 payment systems.
Side effects
- HTTP 402 returned when payment header is missing or invalid — includes EIP-3009 extras for payment resolution
- Origin URL not reachable or misconfigured — may return connection error
- Facilitator other than OpenX402 not supported — request rejected
- Invalid HTTP method (only GET, HEAD, DELETE accepted) — validation error
