Domain WHOIS Lookup - Age, Expiry, Registrar, DNS

Domain WHOIS Lookup is an Apify Actor that returns WHOIS and DNS data for any domain as structured JSON. Each result carries the registrar, registrant, creation, update and expiry dates, domain age, nameservers, status flags and, by default, the A, AAAA, MX, TXT, NS and CNAME records. Look up one domain or up to 20 per request with no API key, or call it as a real time HTTP API in Standby mode.

FAQ

Can I look up more than one domain at a time?

Yes. Put up to 20 domains in the domains array. Bulk requests charge per domain, so a batch of 20 domains costs $0.16 at $0.008 per domain. There is no extra fee for the batch itself.

What input formats does it accept?

A bare domain such as google.com is the normal form. The actor also normalizes full URLs, the www prefix and protocol prefixes, so a pasted URL works too.
