  title: V7 Darwin Annotations Classes 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.'
