Forgive me I did not find the "meta" for the StackApps, I believe it is here that I must ask.

I developed an extension for browsers, but I'm not using the StackExchange API, I can post it on StackApps?

The extension accesses data from this url:

• http://stackexchange.com/topbar/get-unread-counts

Can I do create an application without using the API? This is allowed?

-- Sorry my bad English.
