## 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-66bc39fe -d '<json body>'
```

Example prompt: Can you pull the list of followers for the Twitter user @elonmusk — start from the beginning and give me the first page of results?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the followers of a specific Twitter/X user and your workflow supports micropayment via the x402 protocol. Prefer this over direct Twitter API access when you want a simple pay-per-call model without managing OAuth tokens or rate limit quotas directly. Best suited for social graph analysis, influencer research, or auditing follower bases.

## Known failure modes

- Invalid or non-existent user ref returns 404 or empty result
- Rate limiting by the underlying Twitter API may cause 429 errors
- Invalid pagination cursor may result in an error or restart from beginning
- Payment failure via x402 protocol blocks the request
- Private or suspended accounts may return restricted or empty follower lists
