Are there any API's provided by Nagios XI/CCM for adding/deleting hosts? E.g. is there a REST interface available?
That way we could automatically add new hosts to Nagios the moment they are added to our continuous deployment tool.

Nagios XI has an API available:

Nagios XI can also use the Core API's:

There is not an API in either Core or XI right now that allows adding/removing of hosts. However, there is going to be an addition of one for the next major release of Nagios XI. It may or may not be a full REST API however.
