## 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-6f0429ad
```

Example prompt: Can you pull the list of verified followers for the Twitter account @elonmusk? Page through the results if there are more.

## When to prefer this

Use this endpoint when you specifically need to identify which verified (blue-check) accounts follow a given Twitter/X user, as opposed to all followers. Useful for influence analysis, audience quality assessment, or identifying notable followers. Prefer this over a general followers endpoint when verified status is the key filter.

## Known failure modes

- User ref not found or invalid — likely 404 or empty result
- Account is private — may return empty or restricted response
- Payment failure — x402 payment not processed, returns 402
- Rate limiting — too many requests in a short window
- Invalid or expired pagination cursor — returns error or restarts pagination
