How-To-Guides
WHOIS Lookup by Domain Name
To retrieve WHOIS information using a domain name, simply pass the domainName parameter in your API request. If you query a sub-domain, such as 'api.apifreaks.com', our API will return the WHOIS data for the root domain name, 'apifreaks.com', as sub-domains do not have their own WHOIS records and rely on the root domain's data.
When querying a second-level domain (SLD), like 'uet.edu.pk', the API will provide WHOIS information specific to that SLD. SLDs typically consist of three letters, such as 'edu', and are managed by separate registries with their own WHOIS servers. Therefore, for domains like 'uet.edu.pk', the WHOIS response will pertain to'uet.edu.pk' itself rather than the parent domain 'edu.pk'.

In the WHOIS response, you will notice two types of data: registry data and registrar data. For TLDs like {.}com and {.}.net, both registries and registrars maintain their own WHOIS servers. As a result, the API provides WHOIS information from both sources, giving you a comprehensive view of domain details.
Additionally, the WHOIS raw response is included in the output. This raw data reflects the information queried from both the registrar and registry WHOIS servers, ensuring you have access to the complete and unprocessed WHOIS records.
WHOIS Lookup by URL
You can also retrieve WHOIS information by passing a URL to the API. Our system will automatically extract the domain name from the URL you provide and use it to fetch the necessary WHOIS data. This allows you to easily obtain domain details without needing to manually extract the domain name yourself.
