## 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-twitter-profile-lookup-via-x402-micropayments-cb8af107
```

Example prompt: Can you pull up the X/Twitter profile for the user 'elonmusk' — I want their bio, follower count, and account details — and just pay the $0.05 USDC fee via x402?

## When to prefer this

Choose this endpoint when you need to fetch Twitter/X user profile data without setting up a Twitter developer account or managing API keys. It is ideal for lightweight, pay-per-use access to X profile data using USDC micropayments on Base, particularly in Web3 or agent-native contexts where x402 payment rails are already available.

## Known failure modes

- Username not found — returns error code with empty or null data
- Payment failure via x402 — 402 response if USDC payment not accepted
- Invalid username format — malformed request returns error
- Rate limiting or upstream X API unavailability — service temporarily unavailable
- Network timeout if upstream X/Twitter is slow to respond
