Results
Interactive intelligence tool
Run the check, then ship the workflow
Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Review decision-ready signals
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Automate the workflow that works
Use the request and response examples to turn a one-off check into an API call or recipe.

Key Features
Domain Profile Viewer - WHOIS/RDAP Normalized Profile | DomScan
We show registrar information, registration and expiration dates, nameservers, DNSSEC status, and contact details (when publicly available). Data is fetched from RDAP servers.
WHOIS Lookup
ICANN requires gTLD registries and registrars to provide RDAP, which became the definitive source for gTLD registration information on 28 January 2025. This transition applies to gTLDs; requirements for ccTLDs vary. DomScan uses RDAP where supported. Depending on the TLD and lookup, it may query WHOIS directly or use WHOIS when RDAP is unavailable. Records can omit fields or redact contact details, so treat them as published registration data, not independent proof of a person's identity.
Get profile
Due to GDPR and privacy regulations, most domains now use redacted WHOIS/RDAP data. Contact information is typically only available for corporate registrations or specific TLDs.
Example request
GET /v1/profile?domain=example.comExample response
{
"domain": "example.com",
"nameservers": ["a.iana-servers.net"]
}Built on the same API
The browser experience previews DomScan's structured endpoints, so teams can validate a use case before writing code.

What's the difference between RDAP and WHOIS?

This transition applies to gTLDs; requirements for ccTLDs vary. DomScan uses RDAP where supported. Depending on the TLD and lookup, it may query WHOIS directly or use WHOIS when RDAP is unavailable.

Why can't I see contact information?
