## 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-checker-f00c8467 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use domain availability or status check without committing to a domain registrar subscription. Ideal for agents that occasionally need to verify domain names on demand, especially when integrated with a Base chain USDC wallet for micropayments. Suitable for lightweight, one-off lookups rather than bulk domain monitoring.

## Known failure modes

- Invalid or malformed domain name returns an error
- Unsupported TLD may return incomplete results
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
- Network timeout or upstream registry unavailability causes request failure
- Rate limiting if too many requests are sent in quick succession

## How this service works

## Output

Returns domain availability or registration status data, indicating whether the queried domain name is currently taken, available, or includes additional registration details such as registrar, expiry, or WHOIS-style metadata.
