# Sample code for Bitcoin RPC:
require "json_rpc"

# Set up the HTTP client
http_client = HTTP::Client.new("localhost", 18332)
http_client.basic_auth "rpc_user", "rpc_password"

# Turn it into a JSON-RPC client
client = JsonRpc::HttpClient.new http_client

# Check your balance!
pp client.call(Float64, "getbalance")
