Google opens up Photos Library API to everyone

After being in developers preview over the past few months, Google today announced that its Photos Library API is now generally available. Those who wish to build and test their own experience can join the partner program for a larger integration.  Regardless of mobile, web, or backend developer, users can use the REST API to utilize the best of Google Photos and help people connect, upload, and share from inside the app. Google also announced that it is launching client libraries in multiple languages. With this new development, users can easily find photos, based on what's in the photo, when it was taken, attributes like media format, upload directly to their photo library or an album, organize albums and add titles and locations, use shared albums to easily transfer and collaborate. You can use smart filters, like content categories, to narrow down or exclude certain types of photos and videos and make it easier for users to find the ones they're looking for. Source
