How to specify the default format

[urimaro]

I would like to specify the format.
Could you let me know if you have any better ideas than using the defaults block?

  api vendor_string: 'foo', default_version: 1 do
    defaults format: :json do
      version 1 do
        cache as: 'v1' do
        :
        end
      end
    end
  end
