## 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 x402-twitter-x-user-profile-lookup-10142723
```

Example prompt: Can you pull up the Twitter profile for user ID 44196397 — I need their bio, follower count, and display name? Just pay the micropayment fee, no API key needed.

## When to prefer this

Use this endpoint when you need Twitter/X user profile data without setting up a developer account or managing OAuth tokens. Ideal for agents that can handle x402 micropayments in USDC on Base and need lightweight, pay-per-call access to X user profiles. Prefer over the official Twitter API when avoiding signup friction or long-term API key management matters.

## Known failure modes

- User ID does not exist — returns error code with empty data object
- Payment fails or is insufficient — HTTP 402 response requiring x402 USDC payment on Base
- Rate limiting or upstream Twitter API unavailability — non-zero error code returned
- Malformed or missing user ID parameter — generic error response
