Temporal Nexus API is one of 8 APIs that [Temporal](https://apis.io/providers/temporal-io/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Nexus, Cross-Namespace, and RPC. The published artifact set on APIs.io includes API documentation.

Temporal Nexus connects Temporal applications across namespaces and teams via named Nexus endpoints backed by synchronous and asynchronous Nexus operations. Endpoints are registered through the OperatorService (Create/Get/ Update/Delete/ListNexusEndpoints) and workers serve them through the WorkflowService Nexus task-queue RPCs (PollNexusTaskQueue, RespondNexusTaskCompleted, RespondNexusTaskFailed). Transport is gRPC.
