How this service works
WHOIS domain lookup — raw registry text with registrar, nameservers, lifecycle dates and status, plus the responding server. Use the RDAP endpoint when you need parsed structured data.
Output
A JSON object containing the domain's WHOIS record with registrar name, nameserver list, creation date, expiry date, last-updated date, domain status flags, and the raw authoritative registry response.
Example use cases
Check domain expiry before renewal
“Hey, can you look up the WHOIS info for mybusiness.com? I want to know when it expires so I can make sure we renew it before it lapses.”
Investigate suspicious domain ownership
“I got a phishing email with a link to secure-paypal-login.com — can you pull the WHOIS record and tell me who registered it, when, and what registrar they used?”
Verify nameservers for new domain
“We just transferred clientsite.net to a new host. Can you check the WHOIS record to confirm the nameservers have been updated correctly?”
Technical details
Endpoint
GEThttps://dns.use.x402atlas.com/whoisWhen to prefer
Use this endpoint when you need authoritative domain registration metadata such as registrar, nameservers, and lifecycle dates (creation, expiry, updated). Prefer this over DNS record lookups (A, MX, TXT) when the goal is ownership, registration status, or expiry information rather than DNS resolution. Ideal for domain due diligence, monitoring domain expiry, verifying domain ownership, or investigating suspicious domains.
Side effects
- Domain not found or not registered — returns empty or error response
- WHOIS rate limiting by the authoritative registry — may return incomplete data
- Private/redacted WHOIS records (GDPR) — registrant details may be masked
- Invalid or malformed domain input — may return error or no data
- Registry temporarily unavailable — lookup fails with timeout or error
