## How to call it through Zero

```sh
zero fetch --capability twitter-surf-cascade-fyi-217d9739
```

Example prompt: Can you get me the list of Twitter accounts that kleffew94 is following?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the list of accounts a specific Twitter/X user follows, especially for social graph analysis, influence mapping, or monitoring who someone follows. It is hardcoded to the user kleffew94, so it is only appropriate when querying that specific user's following list.

## Known failure modes

- User not found or account suspended — empty or error response
- Response truncated due to large following list — use cursor for pagination
- Rate limiting or payment failure at $0.004 USDC per call
- Private/protected account — following list may not be accessible
- Invalid or expired pagination cursor

## How this service works

User following

## Output

Returns a paginated list of Twitter/X accounts followed by the specified user (kleffew94), including user profile data. The response may be truncated for large following lists; use the cursor parameter to paginate through results. The example response shows an original payload size of ~59KB.
