The Google Cloud Python SDK by Danny Hermes helps to access the cloud storage features of the API, providing quick start, example applications, and authentication. In addition to Cloud Storage, it also works with Google Cloud Datastore, DNS, PubSub, and Engine APIs. See the JSON API reference available at https://cloud.google.com/storage/docs/json_api/v1/
DropBox recently sat down with Gordon Wintrob over at getputpost.io to reveal how they built their APIs from primitive beginnings to handling over 500 billion calls a year. The Dropbox API lets you work with files, do full-text search and manage file and folder sharing.
Facebook is partnering with cloud hosting service Heroku to
make Facebook application deployment more plug-and-play. The new service likely uses the Heroku API to allow developers to instantly have a basic Facebook app running in minutes instead of hours or days. Facebook's app wizard lets you choose from Heroku's supported languages, then pre-populates an app with working examples of common tasks using the Facebook API.
