API Usage Limits

When you signup with us, your account's initial limit is set to 25,000 queries per hour. This limit increases based on the package that you purchase. When you purchase our 100,000 WHOIS Lookups package ($90), your account's limit is changed to 100,000 queries per hour. When you purchase the Enterprise package (1 Billion WHOIS Lookups), your account's limit is permanently set to 250,000 queries per hour. If you exceed the allocated limit, your access to the API will be blocked for the entire hour. Your account limit is never decreased, even if you purchase a lower package at a later time. Please contact us if you wish to have a higher API usage limit.

Partial WHOIS Records

Only applicable for .COM and .NET domains.

Some domain registrars (like GoDaddy) do not provide a domain's complete WHOIS record on query. For such domain names, we are only able to provide you with the WHOIS data that we receive from the central registry (Verisign). This will contain most of the domain's registration information ("domain_registered", "create_date", "update_date", "expiry_date", "domain_registrar", "name_servers", "domain_status", "dnssec"). However, the domain's ownership details would not be available. Such results are marked ("partial_whois": true). GoDaddy is one of the most common registrar involved in partial WHOIS data. On an average, GoDaddy sends partial WHOIS in about 15-20% of the requests.
