## 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-523bdd46
```

Example prompt: Can you pull up the list of accounts that PinkBrains_io is following on Twitter?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the following list for the specific Twitter/X user PinkBrains_io, especially when building social graph analysis, influencer mapping, or monitoring who a specific account follows. Prefer this over manual Twitter API access when you need a pay-per-call model via the x402 protocol without managing OAuth credentials.

## Known failure modes

- User not found or account suspended — likely returns 404 or empty result
- Invalid or expired pagination cursor — may return error or restart pagination
- Rate limit exceeded — returns 402 or rate-limit error
- Account is private and following list is not public — may return empty or restricted response
- Payment failure via x402 protocol — endpoint returns 402 requiring payment
