  description: The Cilium REST API provides access to Cilium daemon and agent endpoints for managing Kubernetes network policy,
    security, and connectivity. The API is served by the cilium-agent process over a local Unix domain socket and HTTP interface,
    and covers endpoints, identities, cluster nodes, and health status.

  description: The Hubble API is a gRPC-based observability API built on top of Cilium and eBPF that provides deep visibility
    into network flows, DNS queries, HTTP requests, and service communication within Kubernetes clusters. It exposes Observer
    and Peer gRPC services for querying flows, nodes, namespaces, and server status across single nodes or entire clusters
    via Hubble Relay.

  description: The Tetragon gRPC API provides access to eBPF-based security observability and runtime enforcement capabilities.
    It enables querying of kernel-level events including process execution, file access, and network activity, and supports
    defining tracing policies via Kubernetes custom resources for real-time enforcement and event streaming.

  description: The Cilium Operator API provides a REST interface for the Cilium operator component, which handles cluster-wide
    tasks such as garbage collection of Cilium endpoints and identities, node IPAM management, and coordination of cluster
    mesh operations. It exposes health and status endpoints for operator lifecycle management in Kubernetes deployments.

  description: The Hubble Relay API is a gRPC service that aggregates and relays network flow data from multiple Hubble agents
    running across Kubernetes cluster nodes. It provides a single cluster-wide endpoint for the Hubble Observer service, enabling
    centralized queries of flow data, DNS events, and HTTP metrics from all nodes through Hubble Relay without connecting
    to each node individually.
