## How to call it through Zero

```sh
zero fetch --capability twit-api-user-search-2fa2e01f
```

Example prompt: Can you search Twitter/X for users matching 'elonmusk' and show me the top accounts that come up?

- Invalid or expired next_token cursor returns pagination error
- Rate limiting or quota exceeded returns 429 or payment-required error
