Accessing KA answer content to show to search engine spider

Summary:

We have content that normally requires a support contract (ie, logged in user with a specific user group permission) to access. We want that content to show up as "teases" in search engines, so we want an answers/answer_view page to be able to show the first 200 characters of the content and then we will add an "upsell" blurb below it. The idea being that customers will search for content on Google and get our content as part of their normal search.

Content (required):

The problem is that CP pages will not allow REST to access content anonymously if there is a user group assigned to the content. It immediately redirects to our login page if I try to access the content.
