Not sure what you mean by "scripting API"?

if you are using local clones of git repositories, there is no real 
advantage to using cacheRepositories and repositoryOverrides ... they 
were invented to avoid hitting the network for http-based mcz repositories.

The GLASS1 bootstrapping script and the GLASS1 baseline itself still 
uses one or two http mcz repositories ... I am currently working on 
completely eliminating the use of http mcz repositories for the 
bootstrapping scripts and tODE ...

Note that the examples in[1] are using configurations and configurations 
are using http-based mcz repositories ... These days it makes more sense 
to create a github repository and use local clones for your projects 
than to fiddle with cacheRepsitories and repositoryOverrides ...

Perhaps you could be more specific about exactly what you are trying to 
achieve
