  title: Sigmora API
  version: 1.0.0
  description: >-
    The priced, versioned public API. Every call authenticates with a workspace
    API key (`Authorization: Bearer sk_live_…`), names the project it files its
    output under, and reports what it cost. `GET /v1/capabilities` answers what
    this deployment can serve right now and at what price; anything it reports
    as unavailable answers 503 `capability_unavailable` rather than 404.
