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 identifier ('minpingflag'), a diagnostic note confirming the paid response shape, the price ('$0.02'), and the title ('Min Ping Flag'). Unpaid or unauthenticated requests receive HTTP 402 with eip3009 payment-required extras instead.
Example use cases
Validating x402 agent payment integration
“Can you hit the x402-tools minpingflag endpoint and confirm that my agent's eip3009 payment authorization goes through correctly? I want to make sure the $0.02 USDC charge settles before I wire up my production flow.”
Debugging HTTP 402 facilitator response
“I'm getting unexpected HTTP 402 errors in my app — can you probe the minpingflag SKU on x402-tools to check whether the OpenX402 facilitator is returning the right eip3009 extras when payment is missing?”
Smoke-testing new x402 wallet setup
“I just configured a new USDC wallet for x402 payments — can you run the minpingflag diagnostic so I can verify the wallet can actually authorize and pay a live $0.02 x402-gated endpoint?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/minpingflag?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402 micropayment integration — specifically eip3009-based USDC authorization via OpenX402 — is functioning end-to-end. It is purpose-built as a low-cost ($0.02) diagnostic probe rather than a production data service, making it ideal for integration testing, wallet validation, and facilitator debugging.
Side effects
- HTTP 402 returned if x402 payment token is missing or invalid — response includes eip3009 extras describing required payment
- Payment rejected if facilitator other than OpenX402 is used
- Malformed eip3009 authorization causes payment failure and 402 response
- Network timeout if the endpoint is unreachable
- Invalid or missing properties parameter may cause unexpected response shape
