Using decorator to restrict certain specs if unauthorized

Hello,
I'm working with the basic_auth example. It works to disable _ALL_ specs if auth fails. I need to hide some specs, and still show other (public) specs. In other words, only _some_ of the specs should be hidden if request is unauthorized. Most likely using the path or 'endpoint' variable to differentiate.

I'm using flask-restful 0.3.6

Any ideas on how to go about this?

Thank you!
