Can user information be obtained from PID returned by devpay webservices or do I have to use s3 webservices for this?

I want to take a look at an S3 user's 开发者_如何学JAVAinformation (like # of buckets, bucket size, etc.). My question: can I use the PersistentIdentifier (PID) returned by Devpay (ActivateHostedProduct) to see any other information about the user other than the user's subscription status?

Looks like the PID is only good for telling you if a devpay customer is subscribed to your product or not.
