Can I use api call for my own Zenpack ?

hi, all

We are using zenoss for a while , and read a lot of docs about how to build a custom zenpack , finally , I really build one !

I can use python scripts to call api of zenoss itself , veay easily for  integrated into our infrastructure.

But , it seems that all doc miss some things about : How to use api call for our own custom zenpack ?

So , my question here , is :

How should I do to expose my own zenpack to REST API  ?

      means , like zenoss itself , can use http protocal call my zenpack class *method*  with return data json format.

Thanks in advance ,
