## 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-ed06ceb1 -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-request domain availability check without a subscription, especially within a workflow that already uses the KiteEndpoints.ai Mega API Hub for other tasks. Prefer this over registrar APIs when you want USDC micropayment billing on Base chain.

## Known failure modes

- Invalid or malformed domain name input returns an error
- Domain lookup service unavailable returns a 5xx error
- Payment failure (insufficient USDC on Base chain) returns a 402 response
- Empty or missing domain parameter causes a validation error

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.

## Output

Returns a result object containing data about the queried domain, including its availability status and possibly registration details.
