title: Voltage Park On-Demand 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.
