How this service works
WHOIS / RDAP domain registration lookup: registrar, creation (registration) date, expiry date, last updated, EPP status codes and nameservers, returned as clean JSON from the authoritative RDAP source. Domain age and ownership research, expiry monitoring, due diligence. $0.01 per domain.
Output
A clean JSON object containing the domain's registrar name, creation/registration date, expiry date, last-updated date, EPP status codes (e.g. clientTransferProhibited), and nameserver hostnames — all sourced from the authoritative RDAP registry.
Example use cases
Domain acquisition due diligence
“Before I buy the domain vintagevinyl.shop, can you pull its full WHOIS registration info — registrar, creation date, expiry, nameservers, and EPP status — so I can check if it's legitimately available and how old it is?”
Expiry monitoring for competitor domains
“Check the registration details for mytopcompetitor.com so I can see when their domain is set to expire and keep an eye on whether it might lapse.”
Phishing domain ownership investigation
“I received a suspicious email from secure-update-paypal.net — can you pull the WHOIS/RDAP data on that domain so I can see who registered it, when it was created, and what registrar it's on?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/whoisWhen to prefer
Use this endpoint when you need structured, authoritative domain registration metadata (registrar, dates, EPP codes, nameservers) for a single domain — especially for due diligence, expiry monitoring, or ownership investigation. Prefer this over DNS lookup tools when you need registration history and registrar details rather than just DNS records, and over raw WHOIS parsers when you want clean JSON output from RDAP rather than free-text WHOIS.
Side effects
- Domain not found or unregistered — returns empty or error response
- Invalid domain name format — likely returns a 400 or validation error
- RDAP registry unavailable for certain TLDs — may return partial or no data
- Rate limiting or payment failure — returns 402 or 429
- Very new TLDs with no RDAP support may not return data
