## 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 nexusapi-url-expander-27d40443 -d '<json body>'
```

Example prompt: Can you expand this shortened URL for me and show me where it actually goes: https://bit.ly/3xKmQ9p?

## When to prefer this

Use this endpoint when you need to resolve shortened URLs (bit.ly, tinyurl, t.co, etc.) to their original destinations without navigating to them — ideal for security checks, link verification, or recovering tracking-wrapped URLs in automated pipelines that require pay-per-call with no API key setup.

## Known failure modes

- Invalid or malformed URL input returns an error
- Expired or dead short links may return a not-found response
- Private or restricted short URLs may not resolve
- Rate limiting or timeout if the destination server is slow
- Payment failure if USDC balance is insufficient

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

The endpoint returns the fully expanded, original destination URL that the shortened or redirected URL points to, potentially including intermediate redirect hops and the final resolved address.
