  title: Alakazam — Programmable Worlds API
  version: '1.0'
  description: >
    **Alakazam is the programmable worlds API.** Generate playable, AI-rendered
    worlds from a prompt or an image, program their logic, and embed them in
    your own products and games.


    A world is *programmable*: a live graph of states and events you generate,
    then read, edit, fork, drive, and react to through the API. Two surfaces: a
    **Creation API** (generate, read, manage, fork worlds) and a **Runtime/Embed
    API** (mint short-lived session tokens your end-users' browsers use to boot
    an embedded world).


    **Authentication.** Two schemes. Management endpoints (`/v1/apps*`) use your
    Supabase user session. Data endpoints use an **API key** issued per app:
    `pk_…` (publishable, browser-safe, read + embed) and `sk_…` (secret,
    server-only, create worlds + mint sessions). Never ship a secret key to a
    browser.


    **Usage & quota.** Generations and session mints are metered per app and
    reserved before any GPU spend; exceeding the daily quota returns `402`.

    description: Production (placeholder — set to your conjure-service host)
security: []
tags:
  - name: Apps & Keys
    description: >-
      Create apps (tenants) and manage API keys. Authenticated with your user
      session.
  - name: Worlds
    description: >-
      Create, read, manage, and fork SMWorld games. Authenticated with an API
      key.
  - name: Graph editing
    description: >
      Read and program a world's graph — states (nodes), events (edges), and the
      entrance — with deterministic CRUD, a batch op vocabulary, a
      natural-language kernel-agent edit, and the kernel validate/lint gate.
      Every write is validated fail-closed before it persists. Authenticated
      with an API key.
  - name: Versions
    description: >
      Snapshot, branch, check out, and diff a world's graph. Versions form a
      branching tree of full snapshots; a HEAD pointer tracks the working graph.
      Authenticated with an API key.
  - name: Characters
    description: >
      Create, manage, and talk to characters — a SMWorld subtype that pairs a
      stance-graph with a "brain" (persona, lore, voice). CRUD is authenticated
      with an API key; the live talk turn (/say) and voice (/tts) are called
      from the browser with a short-lived session token.

      notifications. Managed with your user session.
