Here's what I get for your PWS when I use the "free" API key that WU hands out to PWS owners. The data is there and you may be able to figure out a way to incorporate it into your site somehow.

}
The call that returned that is:

Replace "yourAPIkeyhere" with your WU API key . You can insert any PWS ID...their system doesn't associate it with the key.
