Klu Models API

  title: Klu Actions Models API
  description: 'REST API for the Klu (klu.ai) LLM app platform. The Klu Engine runs Actions - each encapsulating a prompt template, model config, context (RAG), and output parsing - against input variables to generate completions, and manages the data, feedback, sessions, models, apps, and workspaces around them. Authentication is via a Bearer API key obtained from the workspace API Keys settings.

    NOTE - Endpoints under the Actions, Context, and Apps/Workspaces paths reflect the publicly documented Klu API reference and SDK surface. Where the public docs document a capability via the SDK but do not publish the exact REST path, this spec models the conventional resource path used by the Klu Engine; see review.yml for which operations are documented verbatim versus inferred from the SDK.'
