SCADA

SCADA (Supervisory Control and Data Acquisition) is an industrial control system architecture used to monitor and control industrial processes, infrastructure, and facility-based equipment. It is widely used in manufacturing, energy, water treatment, oil and gas, transportation, and other critical infrastructure sectors to collect real-time data from remote sensors and control equipment. Modern SCADA systems increasingly expose REST APIs, OPC-UA endpoints, and MQTT brokers for integration with enterprise systems, cloud platforms, and AI/ML workloads.

SCADA publishes 5 APIs on the APIs.io network. Tagged areas include Critical Infrastructure, ICS, Industrial Automation, Industrial IoT, and OT Security.

The SCADA catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

SCADA’s developer surface includes documentation, GitHub presence, and 6 more developer resources.
