Bulk WHOIS API

Bulk WHOIS API

Get the latest WHOIS record of multiple domain names at once.

Our Current WHOIS Database contains the latest WHOIS record of only active domain names (over 267 Million), that are currently registered. Using our Bulk WHOIS API, you can fetch the latest WHOIS record of up to 10,000 domain names at a time. The result will contain fully parsed WHOIS data of each domain name, in JSON or XML format.

Get WHOIS of multiple domain names through the following API:

https://api.bigdomaindata.com/?key=XXXXX&bulk_whois=yahoo.com,google.com,facebook.com,twitter.com,amazon.com

Replace the key "XXXXX" with your own API key, generated through the Members Area.
