# Episode action stream + pipeline annotations

> The episode's native action stream plus the engine's annotations on it (detected grasp frame, splice/release frame, travel, eligibility verdict), so a scrubber can overlay exactly what the pipeline detected.

  title: Alakazam Forge API
  version: '1.0'
  description: |
    The Forge Dataset Workbench API: upload or import robotics datasets,
    audit them, propose and run augmentation campaigns, review, and deliver.
    Served by the Forge workbench service at forge.alakazam.gg (not
    api.alakazam.gg).

    description: |
      **Served at `https://forge.alakazam.gg`** (not the main API host). The
      Forge Dataset Workbench is the client surface of the robotics
      data-augmentation service: bring a LeRobot robot dataset, a public
      Hugging Face repo, a resumable chunked upload, or a one-click curated
      sample, and walk one owner-scoped **campaign** through the spine
      Source & Health → Sample → Transform → Run + Verify → Deliver, leaving
      with a verified augmented dataset. Every endpoint requires a **Supabase
      user access token** (`Authorization: Bearer …`, the `UserAuth` scheme);
      a missing or invalid token returns `401`, and another user's campaigns,
      runs, and uploads read as `404`. Errors use the platform envelope
      `{"detail": "…"}`. Nothing bills until **Deliver**, which charges 1
      credit per never-before-billed kept episode from your credits wallet.
  - name: Playground batches
    description: |
      The Forge playground's "describe a change" flow is not a REST surface on
      this host: a described change is submitted as a **scenario batch**
      through the platform (the Supabase RPC `create_scenario_batch`) and its
      progress/results stream back over Supabase realtime on the
      `scenario_batches` table. For the equivalent public REST surface, see
      **Scenario Studio** (`/v1/scenario-batches`).
