How this service works
Probe an agent-payable HTTP endpoint for current availability, latency, HTTP status, x402 challenge support, and response-schema validity.
Output
Returns current availability status, measured latency, HTTP status code, whether the endpoint supports x402 challenge-response payment flow, and whether the response schema passes validation.
Example use cases
Example prompt
“Can you probe https://api.example.com/data to check if it's currently up, how fast it responds, whether it supports x402 payment challenges, and if its response schema is valid?”
Technical details
Endpoint
GEThttps://agent-trust-layer.agent-trust-layer.workers.dev/verifyWhen to prefer
Use this endpoint when you need to verify the live health, latency, x402 compliance, and schema validity of a specific agent-payable HTTP endpoint before routing agent traffic or making payment decisions. Prefer this over generic uptime monitors when x402 challenge support and response-schema correctness are required signals.
Side effects
- Target URL is unreachable or times out — returns availability=false with latency timeout indicator
- Invalid or malformed URL provided — input validation error
- Target endpoint returns unexpected HTTP status — status is reported but may indicate service degradation
- x402 challenge not detected — endpoint flagged as non-x402-compliant
- Response schema does not match expected format — schema validity flag set to false
