When anyone in your organization has assigned keys to the reservation, the list contains those active keys. When none are assigned, the reservation uses every active organization key and the list contains all of them. This is the desired key set, not proof of installation; check authorized_key_fingerprints on each node from GET /v1/orchestrator/nodes. Requires an approved organization and a reservation your organization holds. To see whether each key is installed, read `authorized_key_fingerprints` and `authorized_key_metadata` on the reservation's nodes from [List reserved GPU nodes](/api-reference/nodes/list). CLI equivalents: `ornn ssh-keys assignments list ` and `ornn ssh-keys assignments status `. ## OpenAPI ````yaml openapi.yaml GET /v1/orchestrator/nodes/reservations/{reservation_id}/ssh-keys 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.
