  title: Tetrate Service Bridge REST APIs Clusters API
  description: The Tetrate Service Bridge (TSB) REST API provides programmatic management of the TSB control plane. It exposes endpoints for managing organizations, tenants, workspaces, cluster onboarding, gateway configuration, traffic routing, security policies, and application/API lifecycle management across multi-cluster, multi-cloud service mesh environments. The API uses Protobuf-backed REST resources and supports standard CRUD operations via HTTP verbs.
