## 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 x-twitter-profile-lookup-no-api-key-c3840b69
```

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

## When to prefer this

Choose this endpoint when you need structured public profile data for a specific X/Twitter account by username without setting up Twitter API credentials. It is ideal for lead enrichment, influencer vetting, audience sizing, and handle-to-ID resolution in agentic workflows. Prefer it over scraping or official Twitter API when you need zero-setup access at low per-call cost ($0.005 USDC).

## Known failure modes

- Username not found: returns an error if the handle does not exist or is suspended
- Private account: may return limited or no data for accounts with protected tweets
- Rate limiting: service may throttle high-frequency requests
- Invalid username format: malformed handles may return a validation error
- Account deactivated: deleted accounts return not-found errors
