is it possible to use twitter gem to preform unauthorized requests like in following example - http://stackoverflow.com/questions/4794562/how-can-i-get-a-twitter-screenname-username-with-the-twitter-oauth-gem-using-the ? I'd like to get screen_name by id. but i'd like to do not preform user authentication
Twitter API 1.1 requires that all requests are authenticated. Fortunately, there's an alternative to user authentication: Application-only auth support for which just landed in master (see #387) with additional features being proposed in #393. I don't believe a version has been shipped with these features yet.
