I know that there is an older post here with the same question. But it was asked in 2012 and the answers are also a couple of years old. Also that is about Google+ Photos, and I am asking about Google Photos
Recently Google Photos has been made a shiny new service with new announcements about having unlimited photo uploads (for photo size < 16 MB). I am currently having a service that uploads to Google Drive. I checked Google Developer site but did not find anything related to Google Photos.
So does the new Google Photos have any open API with it? Does anyone have any information? I appreciate your input.
There is now.

The Picasa API is already deprecated.
