## 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 callfount-x-twitter-user-profile-lookup-b666dfa1 -d '<json body>'
```

Example prompt: Can you look up the X/Twitter profile for the user 'elonmusk' and tell me their bio, follower count, and account details?

## When to prefer this

Use this endpoint when you need to retrieve public X/Twitter user profile data without setting up Twitter API credentials or managing API keys. It is ideal for AI agents that need on-demand, pay-per-call social profile lookups with no signup friction. Prefer this over direct Twitter API integration when you want to avoid OAuth setup complexity or need a unified multi-service API that also handles payment via x402 on Base.

## Known failure modes

- Username not found — returns error if the screen name does not exist or has been suspended
- Rate limiting — if too many requests are made in a short period, the endpoint may return rate limit errors
- Invalid pagination cursor — supplying a malformed or expired next_token may result in an error
- Account is private — private or suspended accounts may return limited or no profile data
- Payment failure — if x402 USDC payment is not processed correctly, the request will not complete

## How this service works
