How this service works
Public URL status, latency, and response header subset for uptime and health agents

Returns a JSON object with: ok (boolean indicating success), status (HTTP status code integer), ms (round-trip latency in milliseconds), headers (subset of response headers), and service (string label for the target service).
Example use cases
Example prompt
“Can you do a quick health check on https://api.example.com — tell me if it's up, how fast it responded, and what HTTP status code it returned?”
Technical details
Endpoint
GEThttps://vending-machine-seven.vercel.app/api/v/http-headWhen to prefer
Use this endpoint when you need a lightweight, paid uptime signal for a public HTTPS URL without downloading the full response body. Ideal for agent-driven health monitoring, brand protection pipelines, or pre-flight checks before hitting a dependency. Prefer this over a full GET-based scrape when you only need status, latency, and headers. Part of a suite that also offers TLS cert checks, DNS lookups, and redirect chain following on the same host.
Side effects
- Non-HTTPS or private/local URLs rejected — only public https:// URLs accepted
- Target URL is unreachable or DNS fails — returns ok: false with no status
- Target returns a non-2xx status — ok may be false, status code still returned
- Timeout on slow upstream — returns ok: false, latency may still be reported
- Malformed or missing url query parameter — returns validation error
