## 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 x402-domain-info-68dd3677
```

Example prompt: Can you pull up the domain registration details for openai.com — I want to know who registered it, when it was created, and when it expires?

## When to prefer this

Use this endpoint when you need fast, pay-per-call domain registration intelligence without needing to set up API keys or accounts. It is ideal for AI agents operating autonomously that need on-demand WHOIS-style lookups billed directly in USDC via x402, particularly in workflows investigating domain ownership, age, expiration, or registrar details.

## Known failure modes

- Domain not found or not registered — may return empty or error response
- Invalid domain name format — will likely return a 400-style error
- Domain has redacted WHOIS privacy — registrant details may be masked
- Rate or payment failure — x402 payment not accepted or insufficient USDC
- Network or upstream WHOIS lookup timeout

## How this service works

Domain registration intel for AI agents. Paid per call in USDC on Base via the x402 protocol (v2, exact scheme). No API keys, no accounts.

## Output

Returns domain registration intelligence including registrar name, registration and expiration dates, registrant contact details (where available), name servers, and domain status flags — essentially structured WHOIS data for the queried domain.
