  title: DataCrunch Public API
  description: >-
    Public REST API for DataCrunch, a European GPU cloud. The API lets you
    deploy and manage GPU/CPU instances, query instance types and real-time
    availability, manage OS images and startup scripts, SSH keys, block
    storage volumes, retrieve account balance, and deploy and operate
    serverless container deployments for inference. Authentication uses the
    OAuth 2.0 Client Credentials flow to obtain a short-lived Bearer access
    token.
