How this service works
Expand a shortened or redirecting URL: follows the redirect chain server-side and returns every hop plus the final destination, re-validating each hop against SSRF.
Output
An ordered list of every URL hop in the redirect chain (with HTTP status codes per hop), plus the final resolved destination URL, each hop re-validated against SSRF.
Example use cases
Example prompt
“Can you trace all the redirects for this link and tell me every hop plus the final destination: https://bit.ly/3xAmPLe?”
Technical details
Endpoint
GEThttps://quartermaster.surewhynot.app/v1/unshortenWhen to prefer
Choose this endpoint when you need server-side, safe resolution of a URL redirect chain without exposing your own infrastructure — particularly useful when SSRF safety validation at every hop is required, or when you need the full intermediate hop list rather than just the final URL.
Side effects
- URL is unreachable or times out — returns error with no chain
- SSRF check blocks a hop (e.g. private IP range detected) — chain halted and flagged
- Malformed or non-HTTP URL provided — validation error returned
- Redirect loop detected — returns error indicating circular redirect
- Final destination returns non-redirect status unexpectedly
