Is there a documented Google Reader API yet?

Question

In late 2005, Niall Kennedy blogged about Google Reader’s API: http://www.niallkennedy.com/blog/2005/12/google-reader-api.html

He mentioned that a couple of guys at Google suggested to him that the API might be made official within a couple of weeks.

Has the API ever been officially and publicly documented by Google?

Answer 1

No, despite the talk about Google doing this some day, there is no officially documented Google Reader API yet.

However, the API has been unofficially documented.
