openapi: 3.0.3 info: title: Nagios XI REST Config Disk API description: 'Built-in REST API for Nagios XI, the commercial enterprise distribution of Nagios. The API is split into three sections: Objects (read-only backend for hosts, services, contacts, host groups, etc.), Config (admin-only writes for hosts and services), and System (admin-only commands such as apply configuration, scheduled downtime, status). Responses are returned as JSON when `pretty=1` or by default. Authentication uses a per-user Nagios XI API key passed via the `apikey` query parameter.
