## Overview ( 概述 )

**Apache Zeppelin** 提供了几个 **REST API** ，用于交互和远程激活 **zeppelin** 功能。所有 **REST API** 都可以从以下端点。请注意，**Apache Zeppelin REST API** 接收或返回 **JSON** 对象，建议您安装 **JSON** 查看器如 **[JSONView](https://chrome.google.com/webstore/detail/jsonview/chklaanhfefbnpoihckbnefhakgolnmc) **。

如果您使用 **Apache Zeppelin** 并发现需要一个额外的 **REST API** ，请 [提出问题或向我们发送电子邮件](http://zeppelin.apache.org/community.html) 。

## 解释器REST API列表

这里介绍了 **registered interpreters** ， **settings** ( 设置 ) 和 **interpreters group** 的作用。
