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 ('subminflag'), a descriptive note, the price ('$0.02'), and the title ('Submin Flag'). Unpaid or unauthenticated requests return HTTP 402 with EIP-3009 payment metadata instead.
Example use cases
Verify x402 payment gate on new API
“I just deployed an API with x402 payment gating — can you run the submin flag diagnostic with a GET to confirm the 402 response includes the right EIP-3009 extras and that the paid payload comes back correctly after settlement?”
Debug 402 facilitator integration
“My OpenX402 facilitator integration isn't behaving right — can you probe my origin URL with the submin flag check to see if the HTTP 402 is being returned with the correct payment extras?”
Confirm paid SKU behavior before production
“Before I go live, run a GET submin flag diagnostic against my staging URL to make sure the x402 paid SKU response looks right and the $0.02 USDC payment flow works end to end.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/subminflag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or validate x402 protocol compliance, specifically for the submin flag paid SKU, using OpenX402 as the facilitator. Prefer it over generic HTTP probes when you specifically need to verify EIP-3009 payment extras, confirm paid JSON payloads are served correctly post-settlement, or diagnose x402 micropayment gating behavior.
Side effects
- HTTP 402 returned with EIP-3009 extras if payment header is missing or invalid
- Invalid method returns error (only GET, HEAD, DELETE accepted)
- Malformed URL or origin parameter causes request failure
- OpenX402 facilitator unavailable causes payment verification to fail
- Network timeout on target URL probe
