## When to prefer this

Choose this endpoint when you need to safely resolve shortened or redirected URLs and optionally strip click-tracking parameters before displaying, storing, or acting on the final URL. It is ideal for link-safety checks, cleaning affiliate or marketing URLs, and building link previews. Prefer it over manually following redirects when you need tracking parameters automatically stripped and a clean canonical URL returned.

## Known failure modes

- URL is unreachable or returns a non-2xx status — error indicating the destination is down
- Redirect chain results in a loop — timeout or loop-detection error
- Malformed or non-HTTP(S) URL provided — validation error
- Redirect chain exceeds maximum hop count — truncated result or error
- Destination URL returns an error page rather than a real resource

## How this service works

Follows a shortened link through its redirect chain and returns the final destination with click-tracking parameters removed.

## Output

The final destination URL after following all redirects in the chain, with click-tracking and analytics query parameters removed, giving a clean canonical URL.
