How fast is domain availability checking?
Our availability checks complete in under 500ms for most TLDs. We query registrar databases directly for accurate, real-time results.
What WHOIS data do you provide?
We return registrant info (where available), registrar, nameservers, creation date, expiration date, and domain status.
Can I monitor domains for expiration?
Yes! Set up domain expiration monitoring and receive alerts when domains you're tracking are about to expire.
Which TLDs are supported?
We support 1,500+ TLDs including all major extensions (.com, .org, .net) and country-code TLDs.
Can I try domain lookups for free?
Yes, our free tier is great for building and testing your domain tools. Upgrade when you're ready to offer domain search at scale.
How is WHOIS data affected by GDPR?
GDPR requires redaction of personal registrant data for many TLDs. However, registrar information, nameservers, creation/expiration dates, and domain status remain publicly accessible.
What are the rate limits?
Rate limits vary by plan. Check our pricing page for details. Our plans are designed to support domain research and monitoring tools with generous limits.
Can I check multiple domains at once?
Yes! You can check multiple domains in parallel using concurrent API requests. Bulk checking is supported on all paid plans for efficient domain research.
What happens when a domain is taken?
When a domain is unavailable, the API returns the current registrar information so you can see who manages the domain.
What DNS record types can I lookup?
Our DNS Lookup API supports all major record types including A, AAAA, MX, TXT, CNAME, NS, SOA, PTR, and more for comprehensive DNS analysis.
