## 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-data-gateway-user-profile-by-username-7a9493c2
```

Example prompt: Can you look up the Twitter profile for the username 'naval' and tell me their follower count and user ID?

## When to prefer this

Use this endpoint when you need quick, pay-per-request access to Twitter/X user profile data without setting up an official Twitter API account or managing API keys. Ideal for AI agents that need occasional profile lookups in USDC microtransactions via x402 protocol.

## Known failure modes

- Username not found — returns an error if the handle does not exist or has been deactivated
- Rate limiting or payment failure — x402 payment may be rejected if USDC balance is insufficient
- Private or suspended accounts may return no data or a restricted response
- Malformed username (e.g. including @ symbol) may return an error
