The Quantum API — a GraphQL query surface over the Quantum digital twin graph, letting clients query buildings, floors, zones, surfaces, equipment, components, properties and time-series data from the physics-based ontology. Supports GET and POST, plus GraphQL subscriptions over WebSocket at /api/graphqlSubscribe and QuantumSync real-time data sync at /api/quantumsync. Authenticated with a JWT bearer or a PL-API-KEY header; schema introspection is available to authenticated clients and through the Quantum Insights query builder.
