Project Details

The WHOIS API is a powerful tool that can help businesses, developers, and individuals manage and purchase domain names more efficiently. It allows users to quickly and easily check the validity, availability, expiration, and DNS settings of a given domain name.

One of the key features of this API is the keyword search, which checks if the keyword or domain name is taken in over 300 TLDs and lists which ones are taken. This can be useful for businesses or individuals looking to find a domain name that is available and relevant to their industry or products.

The validation feature ensures that the domain name is valid and correctly formatted according to the rules of the domain name system. This can prevent errors and ensure that the application functions correctly.

The availability feature checks if the domain name is available for purchase, which means it has not been registered by anyone else. This can help businesses or individuals quickly determine if the domain name they want is available.

The expiration feature checks the expiration date of the domain name if it has already been registered. This can help businesses or individuals keep track of when the domain name needs to be renewed.

Finally, the DNS feature checks the DNS settings of the domain name, which can include information about the web server, email server, and other technical details. This can be helpful for developers or businesses who need to manage large numbers of domain names or who need to perform automated checks on domain names.

Overall, the WHOIS API provides easy access to information about the validity, availability, expiration, and DNS settings of domain names, and the keyword search feature can help users find available domain names that are relevant to their needs.
