## 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 x402-forgemesh-io-url-expander-b25358d0 -d '<json body>'
```

Example prompt: Can you trace where this link actually goes before I click it — https://bit.ly/3xKqPWz — and show me the full redirect chain and final destination?

## When to prefer this

Use this endpoint when you need to safely resolve a shortened, obfuscated, or multi-hop redirect URL to its true destination without exposing internal infrastructure. Ideal for phishing triage, affiliate link auditing, or any scenario where you need to know the real endpoint of a link before acting on it. Prefer this over a raw HTTP client when SSRF protection and hop-by-hop chain visibility are required.

## Known failure modes

- URL exceeds 6 redirect hops — chain truncated or error returned
- Target URL is unreachable or returns a network timeout
- SSRF guard blocks internal/private IP address targets
- Malformed or missing URL input returns validation error
- Target server returns non-standard redirect that cannot be followed

## How this service works

URL expansion API: safely follow a short or redirecting link (up to 6 hops, SSRF-guarded) and return the final URL, complete redirect chain, and final HTTP status — see where a link REALLY goes before touching it. For link-safety checks, affiliate auditing, and phishing triage.

## Output

Returns the fully resolved final URL after following all redirects (up to 6 hops), the complete ordered list of intermediate redirect URLs, and the HTTP status code of the final response. SSRF protections are applied to prevent requests to internal/private network addresses.
