Would it be possible to make this system hardcoded into a mod and not just somthing that users download at free will since I'm looking for somthing like this but I'm the type of person that wants users to be able to opt out but at the same time I want it to be hard coded so that I can get the stats I want

You could list OpenEye as a dependency and use ChickenBones's DepLoader to automatically download it.

https://github.com/Chicken-Bones/ForgeMultipart/blob/master/src/codechicken/core/launch/DepLoader.java

This mod will be always stand-alone and never mandatory. Please don't add hard dependency on it.
You are probably looking for something like modstats.org or similar service.
