## 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 kiteendpoints-ai-twitter-user-lookup-api45-2b437a22 -d '<json body>'
```

Example prompt: Can you look up the Twitter profile for @elonmusk and tell me their follower count, bio, and when the account was created?

## When to prefer this

Use this endpoint when you need Twitter/X user profile metadata (bio, follower count, account age, verification status) without direct Twitter API access or developer credentials. It is particularly useful for agents doing social media enrichment, influencer research, or lead qualification at a low per-call cost ($0.14 USDC) via crypto micropayment on Base chain, without needing to manage Twitter OAuth tokens.

## Known failure modes

- User not found — invalid or suspended Twitter handle returns an error
- Rate limiting from upstream API45 provider causing failures
- Ambiguous or missing username input resulting in empty response
- Payment failure if USDC balance is insufficient on Base chain
- Stale or incomplete data if API45 cache is outdated
