## 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-79ba0d4d
```

Example prompt: Can you fetch the list of accounts that @chapterone is following on Twitter/X? Start from the beginning and use pagination if needed.

## When to prefer this

Use this endpoint when you need to retrieve the social graph outbound connections (following list) for a specific Twitter/X user, particularly for social graph analysis, influencer research, or monitoring whose network a particular account is building. Best when you need paginated access to following data and are operating in an x402-enabled payment context.

## Known failure modes

- User not found — invalid or non-existent username returns an error
- Rate limiting or payment failure — x402 payment not processed results in 402 error
- Pagination cursor invalid — stale or malformed cursor returns an error
- Private/protected account — following list may be inaccessible for protected Twitter accounts
- Empty result — user follows no accounts, returns empty list

## How this service works

User following

## Output

Returns a paginated list of Twitter/X user accounts that the specified user (chapterone) is following, including profile data for each followed account and a cursor for fetching the next page of results.
