That's a strong reason for going with a library that is used by multiple users (more people to distribute the workload over). But more realistically, you can just use the existing API endpoints because there are client apps in the wild that rely on those APIs working the same way-- at least until Google sunsets Google Play.
there was an API which i found a while back, but it didn't work at all, all the unit tests it had failed, so my guess was that google changed their api once again and the project was worthless. The solution i came up with was the only reliable one i could build. It was only like 6 lines of code.
