## 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 www-surplusintelligence-ai-b0242243
```

Example prompt: Look up the Twitter/X profile for user ID 44196397 and tell me their display name, username, and account details.

## When to prefer this

Use this endpoint when you have a known numeric Twitter/X user ID and need to retrieve that user's profile information in a single API call. Prefer this over username-based lookup when you already have the numeric ID. Cost-effective at 1 unit ($0.0128 USDC) for individual user lookups.

## Known failure modes

- Invalid or non-numeric userId returns an error
- User ID does not exist on X/Twitter returns a not-found error
- Payment failure or insufficient USDC balance blocks the request
- Rate limiting from the underlying Twitter API v2
- Suspended or deactivated account may return limited data
