## 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 sna4an-domain-checker-api-cb4b6244 -d '<json body>'
```

Example prompt: Can you check if 'coolstartup.io' is available to register?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call domain availability or status check without managing a full registrar API subscription. Best for one-off lookups in automated workflows where $0.1 USDC per call is acceptable.

## Known failure modes

- Invalid or missing domain name returns an error
- Unsupported RapidAPI sub-endpoint path returns 404 or error body
- Payment not provided or insufficient causes 402 response
- RapidAPI upstream timeout causes delayed or empty response
- Malformed params object may cause unexpected API behavior
