Not sure if anyone at Cisco is aware, but the UDS API website is horribly broken.
a sampler of issues I have found:
-the first link on google when I search for 'UDS API Cisco' is a broken link
-scrolling is busted and layout is odd in modern browsers like firefox
-scrolling and layout busted in Safari on iOS
-dead links galore in the API reference and guide
-and so forth
