Wordpress API supports to clone a site in a multisite installation?

I am using the Wordpress JSON API to create a mobile app that can create a site and users in a multisite installation. I am able to create a site and delete a site using the \"Multisite JSON API\" plugin. I am stuck on how to be able to duplicate or clone a template site using this method. Do you have any idea how to do this with or without WPMUDev plugins etc?
