Butlr

Butlr is an AI platform for privacy-first, heat-based (thermal) occupancy sensing that turns anonymous people-sensing into real-time space-utilization insight for workplaces, senior living, higher education, retail, and smart buildings. Its camera-free thermal sensors capture no personally identifiable information while powering occupancy, traffic, presence-time, and heatmap analytics. Butlr exposes an API-first platform: a GraphQL asset-management API for sites, buildings, floors, rooms, zones, hives, and sensors; a RESTful Reporting API (v3) for historical time-series occupancy; real-time webhooks for detections, traffic, and occupancy events; and an official Model Context Protocol (MCP) server for agent access. The company reports 30,000+ deployed sensors generating a billion data points daily across 100M+ square feet in 22 countries.

Butlr publishes 2 APIs on the APIs.io network. Tagged areas include Company, Sensors, Occupancy, People Sensing, and Smart Buildings.

The Butlr catalog on APIs.io includes 2 event-driven AsyncAPI specifications.

Butlr’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 24 more developer resources.

  description: The Butlr Reporting API is a RESTful, time-series occupancy API for historical space-utilization analysis.
    A POST query against a windowing/filter body returns aggregated floor, room, and zone occupancy, entryway traffic, presence
    time, per-interval statistics, and heatmaps with configurable windows (1m/1h/1d), aggregation functions (mean/max/sum/median),
    timezones, and tag-based grouping.
