## 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-username-account-checker-060464b4 -d '<json body>'
```

Example prompt: Can you check if the X (Twitter) username 'morningbloom_co' is available or already taken?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.16 USDC) check on an X/Twitter username or account status without setting up your own Twitter API credentials. It is well-suited for brand research, influencer verification, or username availability checks at scale via micropayment-gated access.

## Known failure modes

- Query string missing or empty — endpoint may return an error or empty result
- Username does not exist on X — may return not-found status
- Rate limiting or payment failure — 402 response if micropayment not processed
- Ambiguous query string — unclear if searching by handle or display name
- X platform API changes may cause stale or inaccurate results
