If you want to return a 404, or raise a RouteNotFound error if the format is not :json, I would add a route constraint like this:

Require JSON format:

# routes.rb
MyApp::Application.routes.draw do
  namespace :api, constraints: { format: 'json' } do
    namespace :v1 do
      resources :posts
    end
  end
end
