How this service works
Uptime/health probe for any public URL: sends a HEAD request (auto GET fallback when the server refuses HEAD), follows redirects with per-hop safety checks, and returns up/down, HTTP status, latency in ms, redirect chain, final URL, and key response headers. Deterministic, no page download — a monitoring probe agents can call on a schedule.
Output
Returns a JSON object with: up (boolean), HTTP status code, latency_ms (round-trip time in milliseconds), redirects (count), final_url (after all redirects), response headers (key-value), checked_at (ISO timestamp), and — if down — an error field explaining the failure (timeout, dns, tls, connection refused, etc.).
Example use cases
Example prompt
“Can you check if https://shop.example.com is currently up and responding, and tell me the HTTP status code, how fast it responded, and whether it redirected anywhere?”
Technical details
Endpoint
GEThttps://api.webbersites.com/api/uptimeWhen to prefer
Use this endpoint when you need a fast, deterministic, no-download probe of whether a public URL is responding — ideal for scheduled uptime checks, pre-flight validation before scraping, verifying redirects, or health monitoring in automated workflows. Prefer this over a full-page fetcher when you only need availability and headers, not page content.
Side effects
- URL is unreachable or times out — up=false with error describing cause (timeout, dns, connection refused)
- TLS/SSL handshake failure — up=false with error='tls'
- Invalid or malformed URL input — likely HTTP 4xx or error response from probe
- Server refuses HEAD and GET fallback also fails — up=false
- Target returns non-standard HTTP response that cannot be parsed
