How this service works
Run one bounded unauthenticated GET against a public API endpoint and report status, redirects, response hash, and an optional text-presence assertion.
Output
Returns the final HTTP status code, any redirect chain encountered, a hash fingerprint of the response body, whether the optional expected text was found in the response, and overall pass/fail of the sanity check assertions.
Example use cases
Pre-deploy API liveness check
“Before I push my release, can you ping https://staging.myapp.com/api/status and confirm it comes back with a 200 and contains the text 'healthy'?”
Third-party dependency uptime check
“Check if https://api.openweathermap.org/data/2.5/weather?q=London is still reachable and returning a 200 — I want to make sure it hasn't gone down.”
Redirect behavior verification
“Can you probe https://old.mysite.com/api/v1/users and tell me what status code it returns and whether it redirects anywhere? I want to confirm the redirect to the new domain is working.”
Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/api-sanityWhen to prefer
Choose this endpoint when you need a fast, cheap, unauthenticated one-shot probe of a public API URL to verify liveness, status code, redirect behavior, and optional text presence — without setting up a full monitoring service. Ideal for pre-deployment checks, dependency validation, or quick sanity confirmation in an automated pipeline.
Side effects
- Target URL is unreachable or times out — returns error status indicating connection failure
- URL fails URI format validation — returns 400-level error before request is made
- Expected text not found in response — assertion fails and result reflects mismatch
- Target returns unexpected HTTP status vs expectedStatus — assertion marked as failed
- Redirect loop or excessive redirects on target endpoint — may result in error or truncated chain report
