## 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 www-surplusintelligence-ai-bcd4f1d7
```

Example prompt: Can you fetch the list of followers for Twitter user ID 12345678 — get up to 50 results?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the follower list of a specific Twitter/X account by numeric user ID and want to pay per-call in USDC without managing your own Twitter API credentials. Prefer this over self-hosted Twitter API access when you need a lightweight, pay-as-you-go solution for follower graph analysis or social intelligence tasks.

## Known failure modes

- Invalid or non-numeric userId returns a 404 or Twitter API error
- userId does not exist — returns Twitter API not found error
- max_results out of range (less than 1 or more than 100) — schema validation error
- Insufficient USDC balance for payment — 402 payment required failure
- Rate limits from Twitter API upstream — may return 429 or error object
- Private/protected account — followers list may be unavailable or empty
