Decoding ajax returned obfuscated image

Myfonts.com offers an open API that generates screenshots like so: http://ift.tt/1IzYUCk

I am trying to use the generated png file using a standard jQuery ajax request like so:

  $.ajax({
    url:'http://ift.tt/1IzYUCk',
    dataType: "html",
    success: function (response) {
      console.log(response);
    }
  });

This is returning some super funky encoded png unicode like so �PNG IHDR*��}PLTE����������� <-- super abbreviated version

At first I tried appending the image as a data URI but that didn't work. Any idea what to do with this data to generate an image? Clicking on the link generates it.
