Hey LudicBits,
It looks like I made a slight mistake in the docs and added a trailing '/' after the {segments} section, both in the abstract description and in the example. If that trailing slash gets removed from the query you posted I now get a response with a 401, which is expected for me because I don't have your OAuth credentials.
I've updated the documentation so it is correct. The sample application does have the correct data, I'd strongly encourage you to download that and check it out if you haven't yet.
Sorry about the confusion, thanks for bringing it to our attention!
