## 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 twitter-surf-cascade-fyi-52822a1e
```

Example prompt: Can you fetch the latest mentions for the Twitter user @3janexyz so I can see who has been tagging them recently?

## When to prefer this

Use this endpoint when you need to retrieve incoming mentions for a specific Twitter/X user, particularly when building social monitoring tools, tracking engagement, or analyzing who is talking about a user. Prefer this over general tweet search when you specifically want the mention timeline for a known user handle.

## Known failure modes

- User not found or invalid username returns empty or error response
- Rate limiting or payment failure returns 402 Payment Required
- Invalid or expired pagination cursor may return unexpected results
- Private or suspended account may return no results or an access error
