I'd be interested to know if it's possible to find out the number of records. The documents are not stored on the blockchain, correct?
No, on the blockchain you only store a bunch of text data (OP_RETURN) that prove the existence of a document (wherever is stored) in a certain point in time.
You do not need to store the document on the blockchain, that's insane.

They use a unique header DOCPROOF, which you can look for on chain
