# 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 [auto$](https://github.com/platform9/pcd-docs-gitbook/blob/main/kubernetes/keystone-identity-api/README.md) mechanism for authentication and [multi-tenancy](https://github.com/platform9/pcd-docs-gitbook/blob/main/kubernetes/tenant-user-administration-regions-tenants/README.md).

## 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.
