How this service works
Trust layer for x402 endpoints: live probe, settlement evidence, verdict tiers. USDC on Base, Mogami-settled.
Output
Returns a JSON object with a numeric trust score (0–100) and a verdict string (e.g. 'live_settling') indicating the endpoint's liveness and payment settlement status based on a live probe and on-chain settlement evidence.
Example use cases
Vet an unknown pay-per-call API
“Before I start using this x402 API at https://unknown-data-api.vercel.app/api/feed, can you pull a trust report on it and tell me the score and verdict so I know if it's actually settling payments?”
Confirm settlement before integrating
“I'm about to integrate https://weather-x402.example.com/forecast into my agent — can you run a trust check on it and confirm it's in the live_settling tier before I commit?”
Monitor a partner endpoint's trust status
“Check the current trust score for https://partner-api.example.com/prices and let me know if the verdict has changed from what it was before — I want to make sure it's still actively settling.”
Technical details
Endpoint
GEThttps://settle-check.vercel.app/api/trust/reportWhen to prefer
Use this endpoint when you need to independently verify whether an x402/micropayment API endpoint is genuinely live and actively settling USDC payments on Base before calling or integrating it. Prefer it over manual testing or generic uptime checkers when settlement evidence and a structured trust verdict are needed, especially for Mogami-settled endpoints discovered via x402scan or similar directories.
Side effects
- Target URL is unreachable or returns unexpected status — verdict may reflect 'not_live' or low score
- Target endpoint does not implement x402 protocol — settlement evidence absent, low score returned
- Invalid or missing 'url' query parameter — request fails with validation error
- Target endpoint is slow to respond — probe may time out, affecting verdict accuracy
- Mogami settlement data unavailable — score computed without on-chain evidence, reduced confidence
