## 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 ggwp-api-hub-domain-checker-e42aa4ac -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 committing to a full domain registrar subscription. Suitable for agents that need to verify domain status on demand, especially within workflows on the Base chain using x402 micropayments.

## Known failure modes

- Invalid or malformed domain name input returns an error
- Domain with unsupported TLD may not return accurate results
- Network timeouts or upstream WHOIS service unavailability
- Rate limiting or payment failure via x402 protocol
- Empty or null domain input causes validation error

## How this service works

All-in-one API hub: Social Media, Jobs, Finance, Crypto, and Tools. Pay-per-call with x402 protocol on Base chain.

## Output
