## 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-api-hub-5662d7d0 -d '<json body>'
```

Example prompt: Pull the latest tweets and profile info for @elonmusk from the Twitter API hub — I need follower count, recent posts, and engagement numbers.

## When to prefer this

Choose this endpoint when you need programmatic access to Twitter/X data — user profiles, timelines, search results, or engagement metrics — and want to pay per call via USDC without a long-term Twitter API subscription. Particularly useful for agents doing social media research, influencer analysis, or content monitoring at moderate scale.

## Known failure modes

- Invalid or suspended Twitter username returns a user-not-found error
- Rate limiting from the underlying Twitter API 45 provider results in 429 errors
- Payment failure via x402 protocol blocks access before the API call is made
- Malformed POST body or missing required fields returns a 400 bad request
- Private/protected Twitter accounts may return empty or restricted data
