But that's the original, wrong, error message.
The problem is that your request is not properly URL-encoded. The 
easiest way to achieve this (which is also much easier to use 
programmatically given an XML request string) looks like this:

HTTPSocket
    httpGetDocument: 'http://testing.shippingapis.com/ShippingAPITest.dll'
    args: ({'API' -> #('Verify').
        'XML' -> #('<AddressValidateRequest ><Address 
ID="0"><Address1></Address1><Address2>6406 Ivy 
Lane</Address2><City>Greenbelt</City><State>MD</State><Zip5></Zip5><Zip4></Zip4></Address></AddressValidateRequest>')
    } as: Dictionary)
accept: 'text/xml'

Note that the dictionary values must be arrays of strings, not simple 
strings. This is a little awkward, but it's how the class is implemented.
I've tested it, it works.
