$ bcbc serve -p :3232

# Query card information via curl
$ curl http://127.0.0.1:3232/cardInfo.json?cardNo=6222021234567890123

# Response
> {"bin":"622202","bank":"ICBC","name":"中国工商银行","type":"DC","length":19}

The bcbc tool is a command-line interface entrypoint. To use the tool, you execute the compiled binary. The application logic is managed by the cmd package, which handles command execution via cmd.Execute().
