How this service works
Liveness/latency pre-flight for a URL: is it up, HTTP status and class, response latency in ms, whether it redirects (and where), content-type and server.
Output
Returns whether the URL is reachable, its HTTP status code and class (2xx/3xx/4xx/5xx), response latency in milliseconds, any redirect destination, the content-type header, and the server header.
Example use cases
Example prompt
“Can you check if https://api.example.com/health is up right now — tell me the HTTP status, how long it took to respond, and whether it redirects anywhere?”
Technical details
Endpoint
GEThttps://quartermaster.surewhynot.app/v1/http-checkWhen to prefer
Use this endpoint when you need a lightweight, single-call liveness and latency check for any public HTTP/HTTPS URL — especially for pre-flight validation before invoking a downstream API, monitoring whether a service is up, or inspecting redirect behavior and server metadata without parsing full response bodies.
Side effects
- URL is malformed or not a valid URI — input validation error
- Target host is unreachable or DNS fails — returns down status with error detail
- Request times out — latency recorded at timeout threshold
- Non-HTTP/HTTPS URL provided — schema validation rejection
- Missing required url query parameter — schema validation error
