## When to prefer this

Use this endpoint when you need live, authoritative WHOIS data for a domain including registrar details, registration/expiration dates, and nameservers, especially when accuracy matters and you want IANA referral following to reach the correct registrar. Prefer over generic DNS-lookup endpoints when registrant ownership or registration metadata is the goal.

## Known failure modes

- Domain not found or unregistered — returns empty or error WHOIS response
- Invalid domain format — may return error or malformed response
- WHOIS rate limiting by upstream registry — may result in timeout or throttled response
- TLD not supported by IANA referral chain — partial or no data returned
- Network timeout reaching upstream WHOIS server
