I think you'll find that it is PHP script that is being called via relative indexing (relative to the root/template path) and that the data you mentioned is being implemented via an "orbital" route, or in turn kind of indirectly, and that would be difficult to call from a foreign server/host.
However, I may be wrong. I'm just saying it's very unlikely to work unless you host the whole package yourself.
But that said it may be worth hanging on for the last word. Just don't get your hopes up, that's all.
