bitcoind json-rpc interface specification Is there any document out there on the internet describing how access the json-rpc interface of the bitcoind daemon? In my case, my application is written with C++, and I want access this interface with this language. In my Kubuntu system, I have run bitcoin-qt and it's listenning on port 8333. I create a bitcoin.conf file on my data directory setting an username and a password. Now I want to know how access this interface using C++.

ps.: I should note that I know about libbitcoin library. I ask for the specification because I am trying find a simplest approach, maybe allowing me write my code in only one or two source code files.
Send HTTP POST requests to the Bitcoin Core RPC server and you will get responses in JSON.
