## 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-list-members-054ddd73
```

Example prompt: Can you pull all the members from the public X list with ID 1234567890 so I can see who's in it?

## When to prefer this

Use this endpoint when you need the full roster of users belonging to a specific public X list and you already have the list's numeric ID. It is more targeted than searching for lists by keyword and more complete than fetching individual user profiles one at a time. Prefer it over general search endpoints when the goal is membership enumeration rather than discovery.

## Known failure modes

- Invalid or non-numeric list_id returns a validation error
- Private or deleted list returns a not-found or unauthorized error
- List with zero members returns an empty data array with result_count of 0
- Pagination cursor from a different list or expired cursor may return an error or unexpected results
- Rate limiting by the underlying X API may cause transient failures

## How this service works

Get members of a public X list.

## Output

Returns an array of user profile objects (with fields like username, display name, bio, follower counts, etc.), a total result_count, a queried_at timestamp, and an optional opaque cursor for fetching the next page of results when the list is large.
