## 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`):

Example prompt: Can you pull up the Twitter/X profile for the user 'elonmusk' using ReadX — I want their bio, follower count, and account details?

## When to prefer this

Choose this endpoint when you need to look up a specific Twitter/X user profile by username or numeric ID without holding Twitter API credentials, and are comfortable paying $0.05 USDC per call via x402 micropayments on Base or Solana. Ideal for agents that need occasional profile lookups rather than high-volume access.

## Known failure modes

- User not found — code non-zero, empty data object returned
- Invalid username or ID format — malformed request error
- Payment failure — x402 micropayment not processed, 402 response before data is returned
- Rate limiting or temporary X/Twitter upstream unavailability
- Suspended or deactivated account returns empty or error response
