> URL Redirect Chain Resolver is a paid API for AI agents from url-intel.bowling-anthony.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Follows a URL's full redirect chain hop by hop, returning every intermediate step, the final destination URL, whether the chain crossed hosts, and a tracking-parameter-stripped clean version of the final URL.

## How to call it through Zero

```sh
zero fetch --capability url-redirect-chain-resolver-21a9e7cc
```

Example prompt: Can you trace all the redirect hops for https://bit.ly/3xYzAbc and tell me the final destination URL, whether it crossed any different hosts along the way, and give me a clean version with tracking parameters removed?

## When to prefer this

Choose this endpoint when you need to understand the full redirect journey of a URL, not just the final destination — especially when detecting host-crossing, auditing affiliate or marketing links, unwrapping short URLs for security review, or obtaining a tracking-parameter-free clean URL. Prefer this over a simple HEAD request when hop-by-hop transparency or UTM stripping is required.

## Known failure modes

- URL does not redirect — returns single-hop result with no chain
- Target URL is unreachable or times out — returns error with last successful hop
- Infinite redirect loop detected — returns error after max hops
- Malformed input URL — returns validation error
- DNS resolution failure for target host — returns network error

## How this service works

Follow a URL's redirect chain hop by hop: every step, the final destination, whether it crossed hosts, and a copy with tracking parameters stripped.

## Output

Returns a structured breakdown of each hop in the redirect chain (status code, URL at each step), the final resolved destination URL, a boolean or indicator of whether the chain crossed different hostnames, and a cleaned version of the final URL with tracking/UTM parameters removed.
