## 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 whois-lookup-with-iana-referral-follow-800f2523
```

Example prompt: Can you pull up the WHOIS record for openai.com and tell me who the registrar is and when the domain expires?

## When to prefer this

Use this endpoint when you need live, authoritative WHOIS data for a domain, including registrar details, registration/expiry dates, and nameservers. Prefer this over DNS lookup endpoints when you need ownership and registration metadata rather than DNS records. The IANA referral follow ensures you get the most accurate registrar-level data rather than just the TLD registry response.

## Known failure modes

- Domain not found or not registered — WHOIS returns empty or NXDOMAIN-equivalent response
- Rate limiting by upstream WHOIS registry — may return error or empty data
- Invalid domain format provided — likely returns a 400 or error JSON
- Upstream IANA or registrar WHOIS server unavailable — timeout or connection error
- Private/redacted WHOIS records (GDPR) — minimal registrant info returned

## How this service works

## Output

Returns the full registrar WHOIS text for the queried domain as a JSON object, sourced live from the relevant registry by following IANA referrals. Includes registration dates, expiry, registrar name, nameservers, and registrant details where available.
