    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.
