I believe we do use the attributes, e.g.

[Authentication(Rights = "A_ACCOUNTS")] 
	[RoutePrefix("api/accounts")]
    public class AccountsApiController : BaseApiController

and then in the methods:

[Route("")]
        public IHttpActionResult GetAccounts(
		[FromUri]AccountSearchViewModel searchViewModel,
		[ModelBinder(typeof(SearchRequestModelBinder))]SearchRequest searchRequest)
        {
            SetUpSearch(searchRequest, searchViewModel);
            return Ok(searchViewModel.Result);
        }

and sometimes using Authentication for methods.
