## 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-lookup-by-id-980bee9c
```

Example prompt: Can you pull the full profile info for the X/Twitter account @elonmusk — I want their bio, follower count, and account ID?

## When to prefer this

Use this endpoint when you need Twitter/X profile data without managing official API keys or OAuth credentials, especially in agentic workflows that support x402 micropayments in USDC on Base or Solana. Ideal for lightweight, on-demand profile lookups at $0.05 per call when you don't need high-volume bulk access.

## Known failure modes

- User not found — returns non-zero code if username or ID does not exist
- Payment failure — 402 response if USDC micropayment via x402 is not completed
- Invalid input — malformed username or ID returns an error
- Rate limiting — too many requests may result in throttling
- Private account — profile data may be limited or unavailable for protected accounts
