  title: Thunder Compute API
  description: >-
    REST API for Thunder Compute, a low-cost GPU cloud offering on-demand
    virtual GPU instances billed per minute. The API manages instance
    lifecycle (create, list, modify, delete), SSH key attachment, forwarded
    HTTP ports, snapshots, account SSH keys, API tokens, and read-only
    pricing and GPU specifications. The tnr CLI and the Thunder Compute
    Terraform provider are both clients of this same API. Endpoints and
    schemas mirror the published OpenAPI document at
    https://api.thundercompute.com:8443/openapi.json.
