Unfortunately no :( I've tried to contact Opscode many times, including a tweet this week and asking in person to an Opscode guy in the first SF meetup I attended, but it seems that there is no documentation for those apis.

Time ago I found [knife-acl](https://github.com/seth/knife-acl) and [knife-opc](https://github.com/stevendanna/knife-opc), and look at the code to start building the apis, but they are not official and I don't know what we can be missing.
