Domain checker tools

A Quick question. I have an app I built in python for my own use only.
It pulls in metrics from ahrefs and majestic and data from them that I am interested in when scanning pbn domains for myself.
Saves all the double filtering, page hopping etc inside the tools.
Would any one be interested in using such a tool for their own usage and if so what would the key features and information you would like it to grab for you?
As this tool I could make public with a little interface tweaking and be sold for a hell of a lot less than their monthly subscriptions for sure. Just an idea and would like your thoughts on it please
