How this service works
The redirect chain of a URL, hop by hop (at most 10 hops): each URL, its status, the Location it points to, and whether the hop goes from http to https or changes host. Returns the final URL and status, total hops, loop true when a URL repeats, and the Strict-Transport-Security header of the final response.
Output
Returns a structured JSON object with the original URL, an ordered array of hops (each with URL, HTTP status code, Location header, host-change flag, and HTTP-to-HTTPS flag), final URL, total hop count, loop detection flag, HSTS status, truncation flag (if more than 10 hops), and a timestamp of when the check was performed.
Example use cases
Debug broken redirect on product page
“Can you follow the redirect chain for http://shop.example.com/old-product and show me every hop with its status code so I can figure out where the redirect is breaking?”
Verify HTTPS upgrade enforcement
“Check if http://mybrand.com properly redirects to HTTPS — show me the full chain of redirects and confirm the final URL is secure.”
Detect redirect loop causing site errors
“Users are reporting a redirect loop on http://legacy.example.com — can you trace all the hops and tell me if there's a loop detected and what the redirect sequence looks like?”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/redirects?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect the full HTTP redirect chain for a single URL — especially useful for SEO auditing, HTTPS enforcement verification, debugging redirect misconfiguration, or detecting redirect loops. It is purpose-built for redirect tracing and returns structured hop-by-hop data including status codes and host changes, making it superior to a generic HTTP HEAD request when you need visibility into intermediate steps.
Side effects
- Invalid or malformed URL returns an error
- Unreachable host results in a connection timeout
- Redirect loops are capped at 10 hops and flagged with truncated=true and loop=true
- Non-HTTP URLs (e.g. ftp://) may not be supported
- Very slow target servers may cause timeout before chain is complete
