## 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 blockbuster-ai-twitter-api45-user-lookup-d06d3fb1 -d '<json body>'
```

Example prompt: Can you pull up the Twitter profile details for @elonmusk — I need their follower count, bio, and whether the account is verified?

## When to prefer this

Use this endpoint when you need to retrieve public Twitter/X user profile data without setting up official Twitter API credentials. Particularly useful for social analytics pipelines, influencer research, or enriching contact data with social media presence. Prefer this over direct Twitter API when you need micropayment-based pay-per-call access via x402 on Base chain.

## Known failure modes

- User not found — returns success: false if username/ID does not exist
- Invalid query format — malformed or empty query string returns an error
- Rate limiting — upstream Twitter API45 quota exceeded results in failure
- Private account — data may be limited for protected Twitter accounts
- Network timeout — Vercel function timeout on slow upstream responses
