  description: Public discovery and representative authenticated ModelRush API contracts. Model and region availability are time-sensitive; call the discovery endpoints before selecting a model or execution region. Authenticated generation operations may create billable usage. Keep API keys server-side. The Apache-2.0 license covers this API description, not access to the hosted service or its underlying implementation. Service use remains governed by the linked terms of service.
