No.  The interface is just the northbound database.  You can write to it
using the OVSDB protocol or the OVN command line tools.  If you use
Python, there's a library you can use, which is what OpenStack uses.

Part of what you get by adding Neutron is a REST API.  That was just the
first integration, though.  Integration in OpenDaylight for example
would be another way to get a REST API (among other things).

Another option would be to write our own simple REST API.  I think it'd
be pretty straight forward using the Python library and one of the
several REST API frameworks.
