How this service works
Run ONE named check against a live endpoint
Output
A JSON report for the single check run: the check ID, whether it was applied, whether it passed, the finding with a specific fix (or null if passing), the compliance regime (e.g. 'payment'), severity level, whether it is a core check, annotated source references (spec or client-code), and an envelope summary including detected versions, payTo address, network, and price.
Example use cases
Debug missing Bazaar listing
“My API passes x402 validate but still isn't showing up in Bazaar — run the V2_B64_URLSAFE check on https://myservice.dev/api/premium and tell me exactly what's wrong and how to fix it.”
Pre-launch compliance verification
“Before I launch, run the x402 V2_B64_URLSAFE lint check on https://api.myproduct.com/generate to confirm the 402 response won't block indexing, and give me the full finding with sources.”
Automated CI check for x402 correctness
“Check https://staging.myapp.io/premium-endpoint with check ID V2_B64_URLSAFE and tell me the severity and whether it passed so I can decide if the build is safe to promote.”
Technical details
Endpoint
POSThttps://10x402.com/lint/oneWhen to prefer
Use this endpoint when you need to diagnose exactly which x402 compliance rule is causing a service to fail indexing or not appear in Bazaar, and you already know (or have retrieved from GET /check) the specific check ID you want to investigate. It gives a precise finding and actionable fix for one check at a time, making it ideal for targeted debugging or CI pipelines that assert individual rules.
Side effects
- Invalid or unreachable target URL returns an error or unapplied check result
- Unknown check ID causes the check not to be applied (applied: false)
- Target server does not return a 402 response, making the check inapplicable
- Malformed request body (missing url or check fields) returns a validation error
- Network timeout to target URL prevents check execution
