Learn more about API integration“WhoisXML API’s database consists of 23.8B+ WHOIS records and has indexed historical WHOIS records over a long period, making their solution one of the best in the market in my opinion.”
“Monitoring our domains would not be possible without WhoisXML API. They give us a neat UI to monitor our brand based on keywords or domains we deem important. This capability is essential to ensure our brands maintain the integrity and reputation we have solidified.”
“The WhoisXML History API has been a game changer for our online investigations, trainings, and books. We have uncovered the true owners behind numerous malicious domains, even though they currently possess "private" Whois registration.”
“Whois XML is one of the most important tools we use for domain intelligence in the Bachelor's Degree program in Investigation and Security Sciences at the University of Perugia. In particular, we appreciate the reverse research from IP to Domain and Whois with query filters. The tool is comprehensive, providing detailed information such as phone numbers, names, and other details from Whois records. While many Whois records are now covered by privacy regulations, WhoisXML API provides access to all historical WHOIS records.”
“WhoisXML was the game changer for us. It has revolutionized our ability to disrupt cybercrime in process and at scale by quickly identifying all of the vendors providing material support for scammers using sophisticated website templates that look legitimate. By quickly identifying the vendors unknowingly supporting the criminals, we can provide them with public interest justification to burn down the criminal infrastructure.”
“The consistent and structured data provided by WhoisXML API made it possible to group and identify who is behind suspected fraudulent websites, being able to search by phone number, address or e-mail address used in the domain registration.”
“I appreciate your products that are useful for checking domain expiration dates.”
“WhoisXML API is amazing for checking out the historic registration information of a domain, pivoting to locate the alternate registrations with the same details and also my cyber investigations. The data proved very useful when investigating pig butchering scams and domains that host child abuse material.”
“DRS is a Great product, easy to use and everything I need in one place.”
“Very useful for investigations, we can go back in history and see when domains were registered and who owned them at a certain time.”
“WhoisXML API builds out data sets that help users correlate attack infrastructure with related IP and WHOIS information.”
