I’m here to help you simplify cyber investigations, threat hunting, and all sorts of other tasks that require working with internet intelligence data.
I have access to 18 different APIs and billions of domain and DNS data points, covering the latest changes on the Internet.
I watch the Internet. All of it. Constantly. I keep track of WHOIS, DNS, IP, and threat intelligence data, covering billions of domains and IP addresses. And I make sure all of it is at your fingertips in a simple chatbot interface. Ask a question — and I’ll show you.
I have access to 18 different APIs and billions of data points. From WHOIS to DNS and from threat intelligence to website categorization — I know it all.
No installation needed, I live in the cloud and I’m ready to help you with your cyber tasks.
No need to code anything. Just talk to me in your language, I’ll understand.
You ask me to run bulk lookups and request complex things that combine different APIs and pivoting off data — I can manage that.
Quickly gather domain ownership history, related IPs, DNS changes, and threat intel. Let me take care of connecting the dots and pivoting so that you don’t need to manually stitch API responses.
Give me a domain or organization name and get a map of associated exposed infrastructure: subdomains, IPs, certificates, and more.
I’ll help you reconstruct threat actor networks and trace suspicious domains or IPs back through pivoting between lookups such as WHOIS, reverse WHOIS, DNS history, and more.
I can help you detect anomalies tied to domain registrations, ownership changes, and email verification in real time.
“To every single person who showed up—who came in early, stayed late, worked shoulder to shoulder with people they’ve never met, and treated every case like it mattered most—THANK YOU. You gave these children more than just safety. You gave them hope, love, and compassion. And you reminded each other that this fight doesn’t have to be lonely.”
“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.”
“The website intelligence is easy to set up and returns everything we need. One reason for this is the documentation of the API, which is well-written and very detailed.”
“Thanks to well-structured and clear API documentation provided by WhoisXML API, we were able to integrate the solution seamlessly into our system with minimal technical challenges.”
“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.”
“After thorough testing, we were thrilled to find that Chronicle DNS Database consistently identified 10 times more 'active' subdomains compared to other options in the market.”
“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.”
“Mozello offers built-in domain registration services to our customers, and we needed an easy-to-implement domain availability checking solution that covers all possible domain names, including exotic ones. WhoisXML API provides right what we need at a reasonable cost and with zero maintenance, plus it is very easy to implement.”
“WhoisXML API is a responsive and reliable provider of domain intelligence. Whenever there are issues, they are quick to respond and resolve them. Working with them is smooth and straightforward.”
“WhoisXML API’s domain intelligence allows us to quickly integrate WHOIS lookups into our security heuristics and algorithms without having to worry about hosting services, staging and merging data, and the complicated task of normalization.”
“Keeping track of new domain registration activity is essential in today's digital economy. We look forward to continuing our collaboration with WhoisXML API to help customer leverage critical domain insights in a secure cloud environment that aligns with their data privacy and governance requirements.”
“WhoisXML API data helps us make informed and automated decisions, filtering invalid email addresses much faster.”
“We needed a simple way of verifying the integrity of user-entered email addresses, and discovered WhoisXML API - it is great value and was really easy to integrate with our systems. Excellent customer service when required, too.”
“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.”
Jake AI is a hosted AI assistant that helps you work with WhoisXML API’s internet intelligence data through a simple chat interface. It connects to 18 APIs, letting you run lookups, combine datasets, and investigate domains, IPs, and threats without the need to code or set up anything.

The team at WhoisXML API named this service in honor of Elizabeth "Jake" Feinler, a pioneering computer scientist who served as a Director of the Network Information Systems Center at the Stanford Research Institute (SRI International) and led Network Information Center (NIC) for the ARPANET, which later became the Internet. She’s credited with the creation of WHOIS and — like Jake AI — certainly knows a lot about the Internet.
Jake AI and the MCP Server offer the same API access but differ in setup and flexibility:
