WhoisXML API - Key Features and Functionality
The WhoisXML API
The WhoisXML API is a comprehensive tool in the domain tools and AI-driven product category, offering several key features that enhance domain and IP intelligence. Here are the main features and how they work:
WHOIS API
The WHOIS API provides the registration details, known as WHOIS record data, for domain names, IP addresses, or email addresses. This API gathers data directly from domain registries, registrars, ISPs, and other major Internet data providers, ensuring near-real-time updates. This feature is crucial for security analysts and investigators as it provides current and accurate ownership and registration information.
Historical Whois API
This API allows users to track all changes in domain ownership and registration over the past decade. It leverages a daily-updated database containing billions of current and historical WHOIS records. This historical data is invaluable for identifying patterns and changes in domain ownership, aiding in cybercrime detection and prevention.
Reverse Whois API
The Reverse Whois API enables users to obtain a list of all linked domains associated with a specific identifier, such as a domain owner’s name, email address, phone number, or postal address. This feature helps in identifying potential threats by linking multiple domains to a single entity, facilitating more effective investigations.
Comprehensive Domain and IP Data Coverage
WhoisXML API boasts an extensive repository covering millions of active domains across over 7,596 gTLDs, ccTLDs, and ccSLDs, as well as IP data covering 99.5% of active IP addresses across 235,000 ISPs and 291,000 locations. This comprehensive coverage ensures that users have access to a vast amount of domain and IP intelligence, which is essential for thorough security investigations.
Up-to-Date and Current Data
The API ensures near-real-time WHOIS and IP data gathering through direct and long-term partnerships with major Internet data providers. This real-time data is critical for making informed and timely security decisions.
Well-Formatted and Unified Data
The data provided by WhoisXML API is well-parsed and unified, making it easy to integrate into various platforms, such as Query.AI, using the Open Cybersecurity Schema Framework (OCSF)-based Query.AI Data Model (QDM). This uniformity ensures that the data is easily consumable and can be normalized into critical data points for investigations.
Integration with Security Platforms
WhoisXML API integrates seamlessly with various security platforms, including SIEM, SOAR, and TIP systems, as well as Security Operations Centers (SOCs) and Managed Security Service Providers (MSSPs). This integration enhances the capabilities of these platforms by providing advanced IP and domain data intelligence, thereby improving network visibility and security.
Daily Updates and Fresh Data

Conclusion
In summary, WhoisXML API offers a suite of tools that provide comprehensive, up-to-date, and well-formatted domain and IP intelligence. These features are essential for security analysts and investigators to conduct faster, more effective investigations and make informed security decisions.
WhoisXML API - Performance and Accuracy
Performance
WhoisXML API is known for its efficient and fast response times. The average response time for email verification requests is around 1-2 seconds, which is crucial for real-time systems. If the same email address is queried multiple times, the response time is significantly reduced to a few hundred milliseconds, indicating the use of server caching. The API also handles multiple checks efficiently, including IP geolocation, reverse IP, threat intelligence, and domain availability, all of which are delivered through RESTful interfaces in popular formats like JSON or XML. This ensures quick and reliable data retrieval.Accuracy
The accuracy of WhoisXML API is supported by its extensive database and smart algorithms. For instance, the Email Verification API checks email addresses against multiple layers to verify their validity, effectively fighting spam and disposable email addresses. This multi-layered approach enhances the accuracy of the verification process. In academic and research contexts, WhoisXML API has been used to analyze patterns characteristic of malicious domains. The data provided by the API has helped researchers develop machine learning algorithms to classify and block dangerous domains, highlighting its accuracy in providing critical Internet data.Data Coverage and Historical Records
WhoisXML API boasts an extensive database that includes over 5 billion historic WHOIS records, 1.2 billion domains and subdomains, 2,864 TLDs & ccTLDs, 8.7 million IP netblocks, and coverage of 99.5% of IP addresses in use. This comprehensive coverage ensures that users have access to both current and historical data, which is particularly useful for investigations and research.Security and Privacy
The API has enhanced security measures to protect data integrity and privacy. Recent updates include improved security protocols to safeguard user data, ensuring that the API meets the highest standards of security and privacy.Limitations and Areas for Improvement
While WhoisXML API is highly regarded for its performance and accuracy, there are some limitations. For example, some WHOIS records are now covered by privacy regulations, which can limit the availability of certain data points. However, WhoisXML API provides access to historical WHOIS records, which helps mitigate this issue to some extent. Additionally, the frequency of WHOIS queries can be limited by the WHOIS protocol itself, and some firewalls may filter out WHOIS queries. To overcome this, subscribing to an API like WhoisXML API or setting up and maintaining a local WHOIS database can be beneficial.Conclusion
In summary, WhoisXML API demonstrates strong performance with fast response times and high accuracy through its extensive database and advanced algorithms. While there are some limitations related to privacy regulations and query frequency, the API’s comprehensive data coverage and enhanced security measures make it a reliable choice in the Domain Tools AI-driven product category.
