## 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 basebuilder2-twitter-tweets-followers-endpoint-60e38285 -d '<json body>'
```

Example prompt: Can you pull the followers list for the Twitter account @elonmusk using the BaseBuilder Twitter API so I can see who's following that profile?

## When to prefer this

Choose this endpoint when you need programmatic access to Twitter/X follower data without managing Twitter's own API keys or rate limits directly. It is particularly useful for agents performing audience analysis, influencer research, or competitor monitoring, where real-time follower lists are needed on demand with per-call USDC micropayment pricing rather than a monthly subscription.

## Known failure modes

- Invalid or non-existent Twitter username returns a 404 or empty result
- Rate limiting or quota exhaustion returns an error indicating the paid limit has been reached
- Missing or malformed authentication/payment header returns 402 Payment Required
- Private or protected accounts may return empty or restricted follower data
- Pagination cursor mismatch may cause duplicate or missing records across pages
