## How to call it through Zero

```sh
zero fetch --capability surf-twitter-user-followers-cad4b4b2
```

Example prompt: Can you pull the followers list for the Twitter account @elonmusk using Surf Twitter's pay-per-use API? I want to see their names, usernames, and follower counts.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-use access to a Twitter user's follower list without maintaining a Twitter developer account or managing API keys — especially useful for lightweight agent workflows that only need occasional follower data and benefit from x402 micropayment billing at $0.004 per call.

## Known failure modes

- Invalid or non-existent user ref returns an error or empty data array
- Rate limit or quota exceeded on the underlying Twitter API returns a 429 or proxy error
- Insufficient USDC balance / failed x402 micropayment results in a 402 Payment Required response
- Malformed {ref} path parameter causes a 404 or 400 error
- Private/protected account may return empty or restricted results
