# Redirect Chain Tracer

> Redirect Chain Tracer is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Traces the full HTTP redirect chain for a URL, returning every hop with status code and latency, the final destination URL, HTTPS status, and total hop count.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability redirect-chain-tracer-8ad687a3
```

Example prompt: Can you trace the full redirect chain for https://bit.ly/3xample and tell me every hop, the final URL it lands on, and whether it ends on HTTPS?

## When to prefer this

Choose this endpoint when you need visibility into every intermediate redirect hop with per-hop latency and status codes, rather than just the final resolved URL. Ideal for SEO audits, affiliate/tracking link inspection, HTTP-to-HTTPS migration verification, and debugging redirect loops. Prefer over a simple URL status check when the intermediate hops and HTTPS terminus matter.

## Known failure modes

- URL is unreachable or returns no response — connection error returned
- URL has no redirects — single-hop result with the original URL as final
- Redirect loop detected — chain terminates early with loop error
- Invalid URL format — input validation error
- Very long redirect chains may hit a hop limit before completion

## How this service works

Trace the full HTTP redirect chain for a URL: every hop with status code and latency, the final URL, whether it ends on HTTPS, and total hops. Link checking, affiliate/tracking link inspection, HTTP-to-HTTPS migration checks and SEO redirect audits. $0.01 per URL.

## Output

Returns an ordered list of every redirect hop (URL, HTTP status code, latency in ms), the final destination URL, a boolean indicating whether the chain ends on HTTPS, and the total number of hops.
