## Known failure modes

- Domain not found or not registered — returns empty or NXDOMAIN-equivalent response
- WHOIS privacy/redaction — registrant contact info may be masked by privacy services
- Rate limiting by upstream WHOIS servers — may return partial or delayed data
- Invalid domain format — request rejected with validation error
- TLD not supported — some ccTLDs may have restricted WHOIS access

## How this service works

Perform a WHOIS lookup for a domain. Returns registrar, creation date, expiry date, name servers, registrant info, and raw WHOIS data.

## Output

Returns WHOIS record data including registrant details (name, organization, email if public), registrar, registration date, expiry date, nameservers, and domain status flags. Every response includes a cryptographic audit record with chain hashing for verifiability.
