  title: Voltage Park On-Demand Bare Metal Virtual Machines API
  description: The all-purpose management API for Voltage Park On-Demand, the GPU cloud offering on-demand and reserved NVIDIA H100 / H200 clusters as bare metal and virtual machines. The API lets developers deploy and manage instant VMs, bare-metal GPU rentals, SSH keys, shared storage, locations, billing, and organization settings. Requests authenticate with a bearer API token created on the Developers page of the Voltage Park dashboard; tokens are valid for one year. The On-Demand platform is served on TensorDock infrastructure.
