# R-Zero

> R-Zero Systems is a San Francisco based building-intelligence company (founded 2020) that uses privacy-first occupancy sensors, indoor-air-quality monitoring and AI to autonomously optimize HVAC ventilation, claiming 20-40% HVAC energy savings with no retrofits. Its R-Zero Connect platform turns sensor telemetry into occupancy analytics, space-utilization insights and portfolio reporting. R-Zero's developer surface comes from CoWorkr, the workplace-sensor company it acquired: a REST API for historical utilization data and a Node.js/DDP Stream API for real-time occupancy events. Both are account-gated - there is no public OpenAPI, GraphQL, MCP or A2A surface.

## APIs

- [CoWorkr REST API](https://rzerosystems.zendesk.com/hc/en-us/sections/4408250694295-API): Pull workplace analytical data - historical and current occupancy, utilization and device records - into BI tools. Host https://api.coworkr.co. Access is permission-gated; request it from support@rzerosystems.com.
- [CoWorkr Stream API](https://coworkr.co/apiaccess): Real-time push of utilization sensor updates over Node.js/DDP, used by partner reservation and workplace-experience apps to show live desk and room availability and auto-cancel ghosted reservations.
