R-Zero

R-Zero Systems is a San Francisco based building-intelligence company founded in 2020 that combines privacy-first occupancy sensors, indoor-air-quality monitoring and AI to autonomously optimize HVAC ventilation in commercial real estate, healthcare and higher-education buildings, claiming 20-40% HVAC energy savings without retrofits or capital investment. Its software platform, R-Zero Connect, turns raw sensor telemetry into occupancy analytics, space-utilization insights and portfolio reporting. R-Zero acquired the workplace-sensor company CoWorkr, whose platform still carries the company's developer surface: a REST API for pulling historical workplace utilization data into BI tooling and a Node.js/DDP Stream API that pushes real-time occupancy events into reservation and workplace-experience applications (AgilQuest, Comfy, iOffice Hummingbird, Serraview, Teem, Tactic, Siemens). Both APIs are account-gated - documentation is served inside the authenticated application and access is granted on request - so no public OpenAPI, GraphQL, MCP or A2A surface is published.

R-Zero publishes 2 APIs on the APIs.io network. Tagged areas include Company, Smart Buildings, Occupancy, Sensors, and Internet of Things.

R-Zero’s developer surface includes documentation, API reference, support, engineering blog, and 20 more developer resources.
