This script written in python3 for sorting and categorizing Shodan API keys that you can find via scraping the internet. I wrote it because i kept finding keys all over the internet even paid though,
this script breaks it down into "paid accounts" and "free accounts" after its done checking for validity of keys and u can save it to a file.
$ sudo pip3 install shodan$ python3 shodankeys -l keys.txt
