Hey there, have you used another programming language to 'use' the API? If you use a programming language such as PHP/PERL/Java/C# you could do your testing for the server workload there and then send events to your Nabaztag?
I've implemented the API in Java so I can create my Nabaztag as an object that I can send events to. If I can do this, I can then write a Java application, create a Nabaztag and send it events.
