## 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-x-user-search-7d9f152a -d '<json body>'
```

Example prompt: Can you search Twitter for users related to 'decentralized finance' and show me the top accounts that come up?

## When to prefer this

Use this endpoint when you need to discover or search for Twitter/X user accounts by keyword, name, or topic — especially when you want a list of relevant accounts rather than tweets. Prefer this over tweet search endpoints when the goal is finding people/accounts rather than content.

## Known failure modes

- Empty results if keyword matches no users
- Rate limiting or quota exceeded errors
- Invalid or missing keyword parameter returns error
- API authentication or payment failure (402)
- Network timeout if Twitter upstream is slow

## How this service works

Search users by keyword

## Output

A list of Twitter/X user profiles matching the search keyword, typically including usernames, display names, profile descriptions, follower counts, and other account metadata returned by the Twitter surf cascade API.
