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.
The API returns comprehensive WHOIS information for a submitted domain, including its validity, availability, registration dates, registrar details, and domain extensions.
Key fields in the response include "domain" (full domain name), "sld" (Second Level Domain), "tld" (Top Level Domain), "valid" (domain validity), "available" (registration availability), "created_at," "updated_at," "expires_at," "registrar," and "whois" (WHOIS server).
The response data is structured in JSON format, making it easy to parse. Each key-value pair provides specific information about the domain, allowing for straightforward integration into applications.
The API provides information on domain validity, availability, registration dates, expiration dates, registrar details, and the WHOIS server, offering a complete overview of the domain's status.
