Our Hosted Bulk WHOIS Web Service provides registration details, also known as WHOIS Records, of domain names or IP addresses.
Bulk WHOIS API provides WHOIS records for a list of Domains/IPs via a single REST API query. It is designed for server-to-server communication between your system and the WhoisXMLAPI.com network using standard HTTP or HTTPS protocols. Query responses are delivered in either XML or JSON format based on your requests which are made via POST methods.
To get started you need a developer's account with WhoisXMLAPI.com. Authentication is required each time in order to use the API. The first 500 Bulk WHOIS API credits are complimentary when you register for a free developer account.
Note that the results are stored for 1 year.
Postman is a desktop and web application that allows you to make requests to an API from a graphical user interface. We recommend using Postman with WhoisXML APIs endpoints when exploring the APIs functionality, as well as when you are troubleshooting issues with your application.
The WhoisXML API Postman collection is available at the following links:
The collection includes a preconfigured environment. You will need to set up the api_key variable to fire each request. Get your personal API KEY on the My products page. If you have questions related to the API, you can ask them here: https://main.whoisxmlapi.com/contact-us
