A secure interface that bridges physical facility hardware (OT) and software orchestration (IT). One API across the protocols a building already speaks, with every action governed and logged.
The Arcestra API turns a facility's passive data into an active, explainable record: what the building is doing, what to change, and what each change returned.
A single, standardized entry point to the facility. The API translates data from cooling, power and compute systems into one unified schema, so you can build dashboards and bring Arcestra intelligence into your own business logic.
Available nowNext upReal-time telemetry streams
Arcestra recommends changes to cooling setpoints, power allocation and workload placement, gated by confidence thresholds and safety overrides. People decide. Your team approves every change before it goes ahead.
Available nowNext upAdvisory modeGuided mode
The API sits above the stack you already run as an operational command layer, connecting to automation, asset management, monitoring and observability tools through a lightweight edge connector.

Protocol adapters normalize telemetry from building, power and IT systems into one unified data schema. Pick a protocol and watch it land in the same shape.
