I'm reviewing the Foreman Smart proxy patches now. They're not in the 
FreeIPA repository yet. However the remaining issues were with 
packaging, code organization, naming.

The Smart Proxy is now specific to Foreman provisioning; it is not a 
full REST interface so it will probably not support all operations you need.

For a full REST interface, patches are welcome but the core FreeIPA team 
has other priorities at the moment.  The RFE ticket is here: 
https://fedorahosted.org/freeipa/ticket/4168.

Have you looked at JSON-RPC interface mentioned earlier in this thread, 
and [6]? It might be cleaner to use that than the command-line interface.
