I'd like to work with rails-api gem special to create API-only application. To provide authentication mechanism I want to use built-in authenticate_or_request_with_http_token method described in Railscasts #352, but this method in missing here.

Does anybody have an experience with on rails-api gem?

P.S. I can see this approach, but is this production-ready?

ruby-on-rails authentication rails-api
