## 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-8fb3cea8
```

Example prompt: Can you fetch the list of Twitter accounts that the user 'programmer' is following, and give me the first page of results?

## When to prefer this

Use this endpoint when you need to retrieve the accounts a specific Twitter/X user follows, particularly for social graph analysis, influencer research, or account relationship mapping. It suits agents that need to programmatically paginate through following lists using cursor-based pagination via the x402 micropayment protocol.

## Known failure modes

- User not found — if the username does not exist on Twitter/X
- Private account — if the account's following list is not publicly accessible
- Rate limiting — too many requests may result in throttling or 402 payment errors
- Empty result — user follows no one
- Truncated response — large following lists may be cut off, requiring pagination via cursor

## How this service works

User following

## Output

Returns a paginated list of Twitter accounts that the specified user follows, including user profile data. The response may be truncated for large following lists, with _truncated indicating if the data was cut and _originalSize indicating the full response size in bytes. Use the cursor query parameter to paginate through additional results.
