Product Overview of WhoisXML API
The WhoisXML API is a comprehensive web service designed to provide detailed domain, IP, and DNS intelligence, catering to the needs of various stakeholders including cybersecurity enterprises, Managed Security Service Providers (MSSPs), Security Operations Centers (SOCs), and other businesses.
What the Product Does
The WhoisXML API gathers and analyzes a vast array of domain ownership and registration data points from an extensive WHOIS database. This service enables users to access registration details, known as WHOIS records, for domain names, IP addresses, and email addresses. The API is instrumental in enhancing network visibility, threat intelligence, and cybersecurity capabilities by providing historical and current data on these entities.
Key Features
- Extensive Data Coverage: The API offers access to billions of current and historical WHOIS, DNS, and IP records, covering over 7,596 generic (gTLDs) and country-code top-level domains (ccTLDs) and second-level domains (ccSLDs).
- Data Formats and Protocols: The API supports RESTful communication using HTTP or HTTPS protocols and delivers query responses in either XML or JSON formats, allowing for easy integration into various systems.
- Authentication and Access: Users can authenticate their requests using a personal API key or Server-to-Server OAuth tokens. The first 500 WHOIS API calls are complimentary with a free developer account.
- Advanced Query Parameters: The API allows for detailed querying with parameters such as `domainName`, `ipWhois`, `checkProxyData`, `outputFormat`, and more, enabling users to customize their data retrieval based on specific needs.
- Historical and Real-Time Data: The API provides access to both historical and real-time WHOIS records, which is crucial for forensic investigations, tracking domain ownership changes, and identifying potential security threats.
- Integration and Automation: The API can be integrated into existing internal systems and commercial applications, including Security Information and Event Management (SIEM), Security Orchestration, Automation, and Response (SOAR), and Threat Intelligence Platforms (TIP). It also supports automation through playbooks and integration with tools like Postman.
- Additional Capabilities: Features include the ability to retrieve IP addresses associated with domains, check proxy/WHOIS guard data, and parse raw WHOIS texts. Users can also set up notifications for low account balances and customize warning thresholds.
Functionality
- Threat Intelligence and Cybersecurity: The API helps in identifying and disrupting cybercrime by providing detailed information on domain registrations, IP addresses, and associated entities. It is particularly useful in investigations involving fraudulent websites, phishing, and other cyber threats.
- Domain Intelligence: Users can perform reverse research from IP to domain and WHOIS, filter queries, and obtain detailed information such as phone numbers, names, and other registration details. This is invaluable for correlating attack infrastructure with related IP and WHOIS information.
- Compliance and Regulatory Needs: The API ensures that the data provided is adequately parsed and normalized to fit into business operations, making it easier to comply with various regulatory requirements.
In summary, the WhoisXML API is a powerful tool for enhancing cybersecurity, domain intelligence, and threat analysis by providing comprehensive and structured data on domain, IP, and DNS records. Its extensive features and functionalities make it an essential resource for a wide range of users, from cybersecurity professionals to researchers and businesses.
