Linkerd Multicluster API is one of 11 APIs that [Linkerd](https://apis.io/providers/linkerd/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Federation, Kubernetes, mTLS, and Multi-Cluster. The published artifact set on APIs.io includes API documentation and an API reference.

The Linkerd Multicluster extension provides Kubernetes CRDs and a gateway component that enables transparent, secure cross-cluster service communication. It uses mTLS to authenticate workloads across cluster boundaries within a unified trust domain, allowing services in different clusters to communicate as if they were local.
