## When to prefer this

Use this endpoint when you need to programmatically retrieve the follower list for a known Twitter/X user by their numeric ID, especially in agentic workflows that require paginated traversal of a follower graph. Prefer this over scraping or direct Twitter API access when you need a pay-per-call model via x402 protocol without managing OAuth credentials yourself.

## Known failure modes

- Invalid or non-existent user ID returns an error or empty result
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Rate limiting or quota exceeded on the underlying Twitter API
- Cursor value is invalid or expired, causing pagination to fail
- User account is private or suspended, resulting in restricted access
