zero fetch --capability readx-x-twitter-following-list-api-a3e2cae4
```

## When to prefer this

Choose this endpoint when you need to programmatically retrieve the following list of any X/Twitter account without managing Twitter API keys or OAuth credentials. Ideal for social graph analysis, audience research, bot detection, or building follower/following relationship data pipelines. Use when you want pay-per-call pricing via USDC micropayments rather than monthly API subscriptions.

## Known failure modes

- Rate limiting or X/Twitter upstream errors may return a non-zero error code
