overall api reference

Hi, is there a PDF or some website that contains all the API reference?
like this sequence:
 
Try
            client = New Idea.IdeaClient
            client.RunThroughVisualScript = True
            db = client.OpenDatabase(dbName)
Catch ex As Exception
 
Where is there a reference for the db object methods for example? That's just an example, but I'm talking about overall API reference.
Thanks
