How to get SP 2013 site taxonomy data in SP 2010 site [JSOM/REST]

Question

I am working on a javascript function for SP 2010 site where i need to fetch some data (Taxonomy) from a 2013 SharePoint site. Is there any way that i can get the SP 2013 site taxonomy data in SP 2010 application using JSOM or REST (JS)? Both the sites are in the same network.
The below code is throwing an error at context = SP.ClientContext(2013 site URL);

Error - Argument Exception. Value doesn't fall within the expected range. Paramenter name : serverRelativeUrl

SP 2010 code -

$(document).ready(function () {

var scriptbase = 2013 site URL/_layouts/15/";


$.getScript(scriptbase + "SP.Taxonomy.js", function () {

context = SP.ClientContext(2013 site URL);

getTaxonomyData();

});

});

You cant connect to an other SharePoint-Site than the local one using JSOM. The Reason it internally connects to the SharePoint-Services of your current Site and then tries to find the Site on that Server, which is not the case.

You could try accessing the Remote-Sites Rest-Webservices using plain Javascript, but you have to enable Cross-Origin-Ressource-Sharing on the remote-Server first (otherwise your browser won´t let you call the remote Services)
