How this service works
Trace the redirect chain of a URL to its final destination without downloading page bodies: every hop with its status code, time and Location header, the final URL, whether the domain changed, and loop detection. Useful before trusting a short link or an ad link. Query: ?url=https://bit.ly/…
Output
Returns the ordered list of redirect hops, each with its URL, HTTP status code, Location header, and response time; the final resolved URL; a flag indicating whether the domain changed between any hops; and a loop-detection indicator if circular redirects are found.
Example use cases
Vetting a suspicious short link
“Before I click this link someone sent me, can you trace where https://t.co/abc123XYZ actually redirects to? Show me every hop and tell me if it ends up on a different domain than it starts.”
Auditing ad link redirects
“I need to inspect this ad network URL — can you unwrap https://ad.doubleclick.net/ddm/trackclk/N1234 and show me the full redirect chain with all the status codes and timing so I can see where it ultimately lands?”
Detecting redirect loops in a broken link
“This URL on our site seems to be broken and might be looping — can you trace the redirects for https://example.com/old-page and check whether there's a redirect loop?”
Technical details
Endpoint
GEThttps://api.x-402.online/v1/url/unwrap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to safely inspect a URL's full redirect path without downloading page bodies — ideal for vetting short links, affiliate links, ad URLs, or any suspicious link before trusting or sharing it. Prefer it over a full page scrape when you only care about where a URL leads, not its content.
Side effects
- Invalid or malformed URL returns an error
- Target server is unreachable or times out mid-chain
- Redirect loop detected and reported as an error or flag
- DNS resolution failure for any hop in the chain
- Chain exceeds maximum hop limit and is truncated
