examples of most/all of the parameters is lacking sample output/responses is almost always lacking, I usually need to perform an a cli call to see what the output will be. Their error messages/codes seem to vary with time / aren't consistent / aren't documented. There are about five different messages I get if my token has timed out I've seen. And I'm mostly an ec2/s3/r53 user, aka the oldest apis. What are the other ones like?
