Bulk WHOis API is a free API for bulk downloading of domain whois data. The API is implemented to open up whois data for legitimate use and is strictly against SPAMMING. Using the API you can download WhoIs data in JSON or WhoIs data in XML format. We are working on a tool / utility to provide bulk WHOis download in csv format for the provided domain names in predefined .csv import format. We are trying hard to improve the API and keep it stable as much as possible. Feel free to contact us for any queries or valuable suggestions.
