The Google Reader API was never publicly released or documented but
developers have reverse-engineered it and built an ecosystem of applications
that use this API implementation for syncing mobile or desktop apps with
Google Reader accounts.A handful of resources are available in various places of the internet but
it’s tedious for developers to get an accurate and extensive idea of how the
API works. This is FeedHQ’s attempt to fix that.
