API keys

This project uses hunter.io to get information from company emails,the first couple "company email" searches dont require a key,if you have an interest in company emails i recommend that you sign up for an account on hunter.io.

Once you get an API key, add it to the file "api-keys.yaml" and rerun the command:

$ buster -f john -m james -l doe -b 13071989

$ buster -f john -m james -l doe -b 13071989 -p gmail.com yahoo.com

$ buster -u johndoe

Generate a company email and returns info associated with it

  • You get 200 email validations/day,use them wisely!
  • When using the -a option,avoid using small words(ex:j,3,66),the shorter the words are the bigger the email list is and therefore more validations are needed
  • when adding an email pattern make sure the service providing the pattern displays it with the right size(facebook,twitter,instagram do...others might not)
  • I dont recommend using with Tor as haveibeenpwnd.com,hunter.io and google wont function properly


  • emailrep.io for being developer friendly
  • khast3x,developer of h8mail which was used as a reference for this README file
  • The OSINT community for being awesome!


  • My Code is ugly,i know...if you know how to do things better let me know!
