## 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 basebuilder-twitter-followers-lookup-bf0ee71a -d '<json body>'
```

Example prompt: How many followers does @elonmusk have on Twitter, and can you get me a list of their most recent followers?

## When to prefer this

Use this endpoint when you need programmatic, paid-API access to Twitter/X follower data without managing your own Twitter developer credentials. Prefer it over direct Twitter API calls when you want x402 micropayment-based access and don't want to handle OAuth or rate limit management yourself.

## Known failure modes

- Invalid or non-existent Twitter username returns a 404 or empty result
- Rate limiting or quota exceeded on the underlying Twitter API returns an error
- Payment failure or insufficient USDC balance results in 402 rejection
- Private/protected Twitter accounts may not return follower data
- Malformed request body missing required user identifier returns 400
