In this article, we will provide you with information and commands about the geemd JSON RPC API.
To start Daemon JSON RPC API server, one must specify a port on which server binds (additionally to standard daemon’s arguments). You can choose any free port. To accomplish this, execute the following command from the command line:

 geemd --rpc-bind-port=2046

If you want Daemon to be accessed from other computers and 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:

 geemd --rpc-bind-ip=0.0.0.0 --rpc-bind-port=2046

Having done the above, you’re now ready to operate with the daemon through the following API URLs (e.g., your IP address is 1.2.3.4):

 http://1.2.3.4:2046/json_rpc
 http://localhost:2046/json_rpc
