I can't even get that page to load in my browser with or without VPN.
Do you have a link to the API documentation?

Sure, it's a really simple example.

Note, the default return request for the data is XML, but I have chosen JSON because it means I don't need to configure XPath to convert it into an exampleSet. Clever use of SelectAttributes, filters, loops, transpose & regular expressions should enable you to the abuse the returned dataset in any way you please.
