Scale AI

aid: scale-ai
name: Scale AI
description: Scale AI is the data engine for AI. The company turns raw data into training data by combining ML-powered pre-labeling
  with multi-tier human review, and ships an extensive REST API and SDKs for managing labeling, evaluation, and generative-AI
  data pipelines. The product portfolio spans the Scale Data Engine (foundational labeling and review), the GenAI Data Engine
  (data for foundation-model training and tuning), the Scale GenAI Platform (deployment and orchestration for generative AI),
  the Automotive Data Engine (LiDAR, sensor fusion, customer dashboards, Nucleus), and Donovan (Scale's defense / public-sector
  AI product). The REST API lives at api.scale.com/v1, supports live and sandbox modes, and is wrapped by official Python
  (scaleapi) and JavaScript (scaleapi) SDKs. The company serves enterprise, insurance, healthcare, and U.S. and global public-sector
  verticals.

  name: Scale REST API
  description: 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).
