# Qbert API

**Qbert** is the Platform9 Kubernetes **cluster manager** which resides on the control plane and enables CRUD (Create, Read, Update, Delete) operations for managed Kubernetes clusters via an exposed REST API endpoint – relying on the [Keystone Identity API](https://docs.platform9.com/managed-kubernetes/apis/keystone-identity-api) mechanism for authentication and [multi-tenancy](https://docs.platform9.com/managed-kubernetes/platform-administration/tenant-user-administration-regions-tenants).

## API Access

You can locate the URL for the Qbert API endpoint specific to your PMK deployment by navigating to API Access > API Endpoints within the PMK UI.

Also note the URL for the Keystone endpoint, which will be necessary to specify when obtaining a [token](https://docs.openstack.org/keystone/latest/admin/tokens-overview.html) used to authenticate with the API.
