## 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 twitter-surf-cascade-fyi-bbd56895
```

Example prompt: Can you pull up the Twitter profile for user ID 745959759057133568 — I want to see their display name, bio, and follower count?

## When to prefer this

Use this endpoint when you have a specific Twitter/X numeric user ID and need to resolve it to a full profile. Ideal for enriching datasets that contain user IDs but lack human-readable profile information. Prefer this over search-based endpoints when the exact user ID is already known, ensuring deterministic resolution rather than fuzzy matching.

## Known failure modes

- User ID not found — returns 404 or empty result if the numeric ID does not correspond to an active account
- Invalid user ID format — non-numeric or malformed IDs result in a bad request error
- Account suspended or deactivated — valid ID but no accessible profile data
- Payment failure — x402 micropayment not completed, request blocked
- Rate limiting — too many requests in a short period returns throttling error
