This API offers a comprehensive domain analysis and verification service, providing complete and up-to-date WHOIS information. Its main purpose is to provide developers, companies, and analysts with automated and reliable access to technical and administrative data about any domain on the Internet.
When the user submits a domain as a parameter (for example, google.com), the API responds with structured information that includes the full domain name, its SLD (Second Level Domain), TLD (Top Level Domain), and an indicator confirming whether the domain is valid and available for registration. It also provides essential data about the domain's lifecycle, such as the creation, last update, and expiration dates, along with the name of the responsible registrar and the corresponding WHOIS server.
Thanks to its clear structure and JSON format, this API can be easily integrated into web applications, control panels, domain monitoring services, or SEO tools. It is also ideal for automated registration projects, domain form validation, or real-time availability checks.
In short, this API is a reliable and versatile tool that provides full visibility into the status and administrative data of any domain, allowing you to automate Internet name verification, research, and management processes efficiently and accurately.
Submit a domain and get back complete WHOIS information: validity, availability, dates, registrar, extension, and updated administrative details.

You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.

Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
