## 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-domain-check-1a9244d5 -d '<json body>'
```

Example prompt: Can you check if the domain 'myawesomestartup.com' is available to register?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-request domain availability check without committing to a registrar account or subscription. It is particularly useful for AI agents that need on-demand domain lookup within a crypto-native payment workflow using USDC on Base chain.

## Known failure modes

- Invalid or malformed domain name input returns an error
- Domain TLD not supported may return empty or error response
- Network or upstream WHOIS lookup failure returns a 5xx error
- Payment failure (insufficient USDC) results in 402 response and no data
- Rate limiting or quota exceeded returns an error
