## 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 blackbobs-ai-domain-checker-616ed323 -d '<json body>'
```

Example prompt: Can you check if the domain name 'morningbloom.coffee' 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 registrar account. Ideal for agents automating brand research, startup naming workflows, or bulk domain vetting where you only pay for what you query.

## Known failure modes

- Invalid domain format provided — returns error if domain string is malformed
- Domain TLD not supported — some obscure TLDs may not be queryable
- Network timeout or upstream WHOIS lookup failure — transient errors possible
- Insufficient USDC balance for x402 micropayment — call rejected before execution
