Daemon JSON RPC API

Daemon JSON RPC API

To start Daemon JSON RPC API server you should specify a port on which server binds (additionally to standard daemon's arguments). You can choose any free port. To do that execute the following command from the command line:
./Qwertycoind --rpc-bind-port=8197
If you want Daemon to be accessed from other computer not only yours you should also use a --rpc-bind-ip 0.0.0.0 command. To do that execute the following command from the command line:
./Qwertycoind --rpc-bind-ip=0.0.0.0 --rpc-bind-port=8197
Having done that you're ready to operate with the daemon through the following API URLs (e.g., your IP address is 126.0.1.100):
http://126.0.1.100:8197/json_rpc
http://localhost:8197/json_rpc
