它使用python3和piston-lib库，用于与steem网络交互。这里有piston-cli和piston-lib的链接。（这里就不给出链接方式了，大家可自行查阅原文）
命令行工具
用叫做piston的命令行工具，可以让你查阅、发帖、回复、资金账号管理等操作。安装之后，你可以使用piston --help命令查看有哪些可用功能。
安装
用pip安装
pip3 install piston-cli
手工安装
git clone https://github.com/xeroc/piston-cli
cd piston-cli
python3 setup.py install --user
更新
pip install --user --upgrade piston-cli

API连接点
this.piston.rocks
我们使用this.piston.rocks作为API的连接端点，但它只是一个试验性质的。你可以免费使用，用于原型验证，但不要指望它是可靠的，也不要用于性能测试。
运行你自己的节点
假设您知道如何编译官方的STEEM守护进程，您也可以运行类似的节点。（链接请查看原文）
steemd节点
下面是steemd的配置文件config.ini：
rpc-endpoint = 127.0.0.1:5090
seed-node=52.38.66.234:2001
seed-node=52.37.169.52:2001

public-api = tag_api
这将打开本地主机的端口5090，接下来，您可以直接向公众开放这个端口，或者通过一个Web服务器(例如nginx)，添加SSL、负载均衡、流控等能力。
Nginx服务器
this.piston.rocks使用了nginx服务，提供了SSL加密、流控、负载平衡等能力，配置如下所示：
upstream websockets { # load balancing two nodes

server 127.0.0.1:5091;
}

}
如upstream配置块所示，它提供了两个steemd节点，用于负载平衡和容错能力。比如一个节点升级代码时，而另一个可以接管整个流量，反之亦然。
