Three modes — IMPORT a complete character world ({ world }, e.g. an example file), EXPLICIT ({ name, persona, stances:[{id,label,expression}], subject, style, voiceId }), or AUTHORED ({ authored:true, premise|frame_* } — the platform invents the profile + stances). Reserves one generation against your daily quota. ## OpenAPI ````yaml /alakazam-v1.yaml post /v1/characters openapi: 3.1.0 info: 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`. servers: - url: https://api.alakazam.gg description: Production (placeholder — set to your conjure-service host) security: [] tags: - name: Apps & Keys description: >- Create apps (tenants) and manage API keys.
