WHOIS / RDAP
Competitive IntelligenceTestedDomain registration, registrar, expiry dates, nameservers, and ownership information.
WHOIS/RDAP reveals domain registration details — who registered a domain, when it was created, when it expires, and which registrar manages it. Agentcy queries the RDAP protocol (the modern successor to WHOIS) for structured, machine-readable registration data.
Ask about a domain's age, expiry date, registrar, or nameservers. This is useful for competitive analysis (how long has a competitor been around?), due diligence (is this domain about to expire?), and domain portfolio management.
This is a zero-config service using public RDAP servers — no API key or domain setup required.
“Who registered this domain?”
“When does this domain expire?”
“How old is this domain?”
“What registrar is this domain with?”
“What are the nameservers for this domain?”
“When was example.com first registered?”
“Is this domain about to expire?”
“What's the domain status for my competitor's site?”
“Check the registration details for this domain”
“Who owns this domain?”

Start asking about any domain's registration details
24-hour cache. Registration data changes infrequently.
Many domains use privacy protection services — registrant contact details will show the privacy service instead of the actual owner
Some TLDs (.io, country codes) may have limited RDAP support — data availability varies
Domain age is calculated from the registration date, which may differ from when the current owner acquired it
RDAP data is public and read-only — no authentication needed
