Shadow GPU (OpenStack API)
Shadow GPU is Shadow's sovereign GPU cloud, delivered as a curated OpenStack 2024.1 deployment rather than a bespoke REST API. Every programmatic action — launching NVIDIA RTX 2000 Ada or RTX A4500 GPU instances, attaching Cinder volumes, wiring Neutron networks and Octavia load balancers, managing Barbican secrets, reading CloudKitty usage — is performed against the standard OpenStack service APIs. Authentication is Keystone: a domain-scoped user (user#domain) or, for automation, an Application Credential, delivered as a clouds.yaml or openrc.sh downloaded from the dashboard. The Keystone identity endpoint answers anonymously and self-identifies at https://auth..os.shadow.tech/v3; the rest of the service catalog is returned only inside an authenticated token response, so per-service endpoints are not publicly enumerable. Shadow publishes no OpenAPI document for this surface and points users to the upstream OpenStack API reference.
