## 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-check-api-f53ff153 -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 check without managing a full domain registrar API integration. Best suited for lightweight lookups where you already know the RapidAPI sub-endpoint path to use.

## Known failure modes

- Invalid or missing 'path' parameter returns an error or empty response
- Malformed domain name input may yield no results
- RapidAPI upstream rate limit exceeded returns a 429 or error object
- Payment not processed (402) blocks the request
- Unknown sub-endpoint path returns a 404 or empty JSON object
