Can you raise a AJAX request inside SoloLearn's Playground?

Question

Hi,
I tried creating a currency converter. It basically gets the currency conversion rates from Fixer.io API and calculates the converted amounts and scripts in the HTML.
It worked perfectly fine in JsFiddle and CodePen but the request throws an error in SoloLearn.
So I assume you can't do that yet in SoloLearn or did I make a mistake? Any precautions to follow?

Since AJAX sends HTTP requests to a server, it cannot be used in Sololearn as there's no server here
