How this service works
Expand short links and show the full redirect chain — Genesis402 / UnyKorn Operator Network
Output
The agent receives the full redirect chain for the provided URL, including each intermediate URL visited, the HTTP status codes for each hop, and the final resolved destination URL.
Example use cases
Verify a suspicious phishing link
“I got an email with this short link https://tinyurl.com/susp1c10us — can you expand it and show me all the redirect steps so I can see if it's trying to hide where it really goes?”
Audit affiliate redirect chain
“Can you trace all the redirects for https://go.affiliate-network.com/click/abc123 so I can see every domain it hops through before landing on the product page?”
Resolve a social media shortened link
“What's the real URL behind https://t.co/K7mNpQrStU? Show me the full redirect chain so I know exactly where it ends up.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/web/unshorten?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect every hop in a URL's redirect chain rather than just the final destination. It is ideal for security auditing of suspicious short links, verifying affiliate or tracking redirect paths, and checking whether a link passes through any unexpected or malicious intermediate domains. Prefer this over a simple HTTP HEAD request when full hop-by-hop visibility is required.
Side effects
- URL is not publicly reachable — endpoint may time out or return an error
- Input URL is malformed or missing scheme — validation error returned
- Redirect chain is too long (redirect loops) — may hit a hop limit and return partial chain
- Target server is down or returns non-standard redirects — incomplete chain
- URL requires authentication or is behind a paywall — cannot follow private redirects
