Background

I would like to create an app for general Stack Overflow browsing to improve upon the UI. One of the things that I am targeting is the lack of certain options in the close dialog. I understand and agree with the reason many options aren't available, like extra sites in the "belongs somewhere else" category, and just more options under off-topic. It can get overwhelming for users, so the most useful ones are presented. However to more adept users the "other" box is often the only tool to explain what's wrong.

Request

I would like an API method to close posts. Preferably it would be generic and allow me to do everything the normal close dialog does. That is to say, get a list of the default reasons (and subreasons), close based on any of those default reasons, or close with an "other" reason.
