The HomeGraph API is the cloud surface that smart-home device makers use to keep Google Assistant in sync with the state of devices in a user's home. Cloud-to-cloud integrations call HomeGraph to request a fresh device sync after the user adds or removes hardware, push state and notification updates when a device changes (lights turn on, door is unlocked), and query the current state of devices Assistant has cached. The API is paired with the Smart Home action fulfilment pattern: device makers serve their own intent handlers and use HomeGraph to keep Google's home graph in sync.
5 endpointsThe Google SAS Portal API administers Spectrum Access System deployments for the CBRS 3.5 GHz radio band, the framework that Google uses to coordinate shared wireless spectrum in the United States. It exposes endpoints to manage customers, deployments, GCP project bindings, legacy organization migration, installer secret generation and validation, and access policies. The portal is used by SAS administrators and CBRS device installers to configure how customer devices are registered with Google's SAS service.
24 endpointsThe SAS Portal API (Testing) is the Google Spectrum Access System staging surface used for managing CBRS (Citizens Broadband Radio Service) deployments, customers, nodes, devices, and installer workflows. It exposes operations for provisioning customer hierarchies, registering and validating CBSDs, signing devices, and managing deployment-level Google Cloud project bindings. The testing endpoint mirrors production semantics so integrators can exercise SAS workflows safely before promoting them to live spectrum operations.
