What does WhoAPI offer?

WhoAPI is a digital service that offers various tools and insights related to domains and websites, including a multitude of API-centric services. These services empower users to aggregate data and conduct thorough evaluations on aspects such as domain names and websites. One of the primary offerings of WhoAPI includes comprehensive domain data. It supplies extensive information related to domain names like registration specifics, expiry dates, name servers, DNS records, and WHOIS data. This information is particularly beneficial for domain investors, website owners, and individuals who require detailed domain-related information for their research or work. Another critical functionality of WhoAPI is its ability to evaluate website performance. It enables users to run checks on websites to measure their health and performance. Aspects like SSL certificate validity, blacklist status, and other factors that impact a website's security and functionality are included in this evaluation. WhoAPI also delivers a unique service through its email verification API. It's a tool that allows users to confirm the validity and deliverability of email addresses. This functionality can greatly support activities such as email marketing campaigns, maintaining customer databases, and improving customer segmentation by ensuring the authenticity of the email addresses. Finally, the service also provides a domain availability feature. By using WhoAPI's Domain Availability API, users can determine the status of a domain name, whether it is available for registration, or monitor any changes in the status of specific domains. This feature simplifies the process of finding and identifying available domain names.
