Chrome Extension: Which Api to get ratings?

Question

I have written a chrome extension which uses the google+ - api to collect some basic information about the user.

I now would like to display something like "Thank you for rating this extension on the chrome web store".

How can I find out if a user rated my extension? Which Api do I have to use? The "Chrome Web Store API" seems to be the wrong one.

Answer 1

There is no public API for getting Chrome Web Store information or ratings.

Edit: There is a Chrome Web Store API, however it's current implementation is designed for automated extension updating/publishing.
