I can't authenticate against the api

Hi

I'm trying to use your developer api but I can't even authenticate.

I've tried both the sample using curl at the top of your API documentation, and a quick ruby test script using ActiveResource. Both are failing to authenticate. I've found enabled the API in the settings. It does list an api key in the settings but the documentation suggests I should be using normal login details. I've tried using the api key in the ActiveResource script as well (self.user = 'apikey') without success.

Thanks

Jeremy
