This is a tool that lets you query whoxy api to look for reverse who is domain names based on your search criteria. It was built upon Whoxy API based on @jhaddix's talk on Bug Hunter's Methodology v4.02.
$ whoxyrm -company-name "Oath Inc."
or
$ whoxyrm -name "Oath Inc."
or
$ whoxyrm -email "test@example.com"
or
$ whoxyrm -keyword "yahoo.com"
$ go install github.com/milindpurswani/whoxyrm@latest
Also, Make sure you export your whoxy api key as follows: without this, it won't work.
$ export WHOXY_API_KEY="..."
you can grab one from https://www.whoxy.com
