## 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-b58df028
```

Example prompt: Can you pull the list of Twitter accounts that kosmosvc is following? Get me the first page of results.

## When to prefer this

Use this endpoint when you need to programmatically access the following list of the specific Twitter/X user 'kosmosvc' via a pay-per-call x402 micropayment model, without needing a Twitter API key. Prefer this over the Twitter official API when you want a lightweight, no-auth-setup approach to social graph data with per-call USDC billing.

## Known failure modes

- User not found — invalid or non-existent username returns an error
- Rate limit exceeded — too many requests return a 429 or similar error
- Payment failure — insufficient USDC balance or x402 payment issue prevents access
- Empty following list — user follows nobody, returns empty array
- Invalid cursor — malformed or expired pagination cursor results in an error

## How this service works

User following

## Output

Returns a paginated list of Twitter/X user accounts that the target user (kosmosvc) follows, including user profile data for each followed account and a pagination cursor to fetch subsequent pages.
