An API key acts as its creator, so it can remove only assignments made by that person. If no assigned keys remain, the reservation returns to its default and every active organization key is queued. To stop a key from working everywhere, revoke it instead. Existing SSH sessions stay connected. Unassigning a key does not revoke it. To block a key on every reservation, [revoke it](/api-reference/ssh-keys/revoke). ## OpenAPI ````yaml openapi.yaml DELETE /v1/orchestrator/nodes/reservations/{reservation_id}/ssh-keys/{key_id} openapi: 3.1.0 info: title: Ornn compute API version: 1.0.0 description: >- Customer HTTP API for Ornn GPU capacity. It covers reserved capacity and nodes, VM and Bare Metal access, Kubernetes and Slurm clusters, SSH keys, storage volumes and GitHub repositories, private networks, monitoring, buying and selling capacity (Reserve, Market, Spot, and Relist), and billing. API keys are scoped to one organization and act with their creator's access there; account, team, and API-key management stay in the console. Most operations require an approved organization. See https://docs.ornn.com/api-keys to create a key and https://docs.ornn.com/guides/kubernetes-api for an end-to-end Kubernetes integration. Examples use fictional IDs and credentials. The info.version field identifies the contract revision, not a shared API path version. contact: email: support@ornn.com servers: - url: https://api.ornn.com description: Production security: - OrnnApiKey: [] tags: - name: Authentication - name: Reservations - name: GPU nodes - name: Clusters - name: Workers - name: Virtual machines description: >- Choose a VM disk, launch VM access on a reservation, and read each VM's status, launch progress, and SSH connection details. - name: Bare Metal description: >- Launch Bare Metal access on a reservation, read a host's readiness and SSH connection details, and reboot or hard reset it. - name: SSH keys description: >- Register public keys for your organization, choose which keys a VM or Bare Metal reservation uses, and queue key delivery to machines.
