How this service works
Primary-source tools for AI agents: verify before you pay, cite, or repeat.
Output
Returns a JSON object with a letter grade (e.g. 'A', 'B'), an integer quality score (0–100), and an array of specific fix suggestions describing what the endpoint is missing or misconfigured.
Example use cases
Pre-launch x402 API compliance check
“Before I list my API on Bazaar, can you run an audit on my x402 GET endpoint at https://myservice.example.com/weather and tell me my score and what I need to fix?”
Debug failing x402 discovery
“My API at https://api.myapp.com/report using GET isn't showing up in x402 discovery — can you audit it and tell me what's wrong?”
Validate API before agent payment
“I'm about to have my agent pay for calls to https://partner-api.io/transcribe via GET — can you audit that x402 endpoint first and make sure it's legit and well-configured?”
Technical details
Endpoint
GEThttps://agent-tools-7936.onrender.com/audit/x402?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402-enabled API endpoint is correctly configured, discoverable, and meets quality standards before paying for it, publishing it, or integrating it into an agent workflow. It is the right choice when you want a machine-readable grade and actionable fix list rather than a generic HTTP health check.
Side effects
- Target URL is unreachable or returns a non-x402 response — audit cannot proceed
- Invalid or missing URL query parameter — returns validation error
- Target endpoint does not implement x402 at all — may return low score or error
- Rate limits or payment issues with the audit endpoint itself
- Slow target endpoint may cause timeout during audit probe
