Nexar is a physical-AI infrastructure company that operates one of the largest real-world video driving datasets — over 1.2 billion miles of driving captured each year by more than 350,000 connected dashcams — and turns it into training data, collision-prediction models and real-time road intelligence for autonomous-vehicle, ADAS, mapping and smart-city programs. Its developer-facing surface is the CityStream™ family of REST APIs, published as four OpenAPI 3.0.1 contracts on the Nexar Developers Portal: VirtualCam (anonymized road frames), Live Feed (real-time detections), Work Zones (curated construction-zone detections, served as WZDx and GeoJSON) and Road Inventory (curated traffic-sign and road-asset detections). All four run on a single gRPC-gateway backed host and are authorized with a bearer access token minted through Nexar's Okta authorization server. Nexar also publishes the open-source BADAS collision-prediction model on PyPI and the `nap` platform CLI through its own Homebrew tap.
