How to find simple secured web services online?

I am trying to write a test code against some secured web service.

So, I've searched the web for some (https) web service to write the client against but didn't find.

I've l开发者_运维问答ooked in one or more UDDI but without any results.

If I'm not mistaken, a bunch of Amazon Web Services ( http://aws.amazon.com ) have HTTPS endpoints. Also, you can try searching on http://www.programmableweb.com
