My apologies:

Well I run the software Sapphire and bitcoin core. It has a command line to send request to the workers i believe. By the way is the user of the software considered a client, miner or user? Anyways here is a couple of examples of what i am talking about.

== Blockchain ==
getbestblockhash
getblock "hash" ( verbose )
getblockchaininfo

And many more we can discuss if desired Some things I wonder is if the sender(me) uses plain English for the message or some type of coding language like html get combined with some of the command line options?
