  title: TensorDock Instances API
  description: |
    The current TensorDock Instances API (v2) for creating, listing, inspecting,
    starting, stopping, modifying, and deleting GPU and CPU virtual machines on
    the TensorDock marketplace. Authentication uses a Bearer token generated
    from the Developer Settings page at https://dashboard.tensordock.com/api.

    Requests and responses follow a JSON:API-style envelope with `data.type`,
    `data.id`, and `data.attributes` fields. Rate limited at 100 requests per
    minute per organization.
