## 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 readx-x-twitter-user-profile-api-08ba6dd9
```

Example prompt: Look up the X/Twitter profile for user ID 44196397 — I want their display name, bio, and follower count.

## When to prefer this

Use this endpoint when you need to fetch Twitter/X user profile data without registering for X API keys, want pay-per-call pricing in USDC (no subscription), or are building autonomous agents that need on-demand social profile lookups on Base or Solana.

## Known failure modes

- User ID not found — returns error code in JSON response
- Invalid user ID format — malformed request
- Payment failure — x402 micropayment not accepted or insufficient USDC balance
- Rate limiting or network timeout from underlying X/Twitter data source
- Suspended or deactivated account — user data unavailable
