  title: V7 Darwin API
  description: >-
    REST API for the V7 Darwin training-data platform. Manage datasets, register
    and upload items (images, video, documents), read and import annotations,
    orchestrate human-in-the-loop workflows and stages, manage annotation
    classes, and request dataset exports (releases). All requests are
    authenticated with an `Authorization: ApiKey {key}` header. Paths use the
    team slug as a path parameter; API keys are scoped to a team and their
    permissions determine which operations are allowed.
