Scale REST API

The Scale REST API is the unified programmatic surface for Scale's data engine. It is built on REST principles with resource-oriented URLs, form-encoded request bodies, JSON responses, and standard HTTP status codes. Endpoints cover tasks (create, retrieve, cancel, set metadata, manage tags and unique identifiers), batches (create, finalize, list, prioritize, retrieve status), projects (creation and management), specialized annotation tasks (image and video, sensor fusion, LiDAR, multi-stage tasks), data retrieval and downloads, taxonomy service management, and callbacks for async operations. The API is versioned (v1), supports live and sandbox modes, and operates on one object per request (no bulk updates).
