I generally support this. When dealing with API endpoints especially I like to wrap them in a class that ends up being. I also like having nested data structures as their own class sometimes too. Depends on complexity & need of course.

    class GetThingResult
      def initialize(json)
        @json = json
      end
    
      # single thing
      def thing_id
        @json.dig('wrapper', 'metadata', 'id')
      end
    
      # multiple things
      def history
        @json['history'].map { |h| ThingHistory.new(h) }
      end
      ... two dozen more things
    end
