## How to call it through Zero

```sh
zero fetch --capability surf-twitter-user-following-list-b96e3207
```

Example prompt: Can you pull the list of accounts that @naval is following on Twitter, including their follower counts?

## When to prefer this

Use this endpoint when you need programmatic, pay-per-use access to a Twitter/X user's following list without managing OAuth credentials or Twitter API rate limits directly. It is ideal for social graph analysis, influence mapping, or monitoring which accounts a user starts or stops following, especially in automated agent workflows that leverage x402 micropayments.

## Known failure modes

- Invalid or non-existent user reference returns an empty data array or 404-equivalent error
- Rate limiting or payment failure via x402 returns a 402 Payment Required response
- Private/protected accounts may return empty or unauthorized response
- Pagination errors if next-page token is malformed or expired
- Network timeout on the upstream Twitter/X API
