**APIs profiled:** 9

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.
