## What is a Standalone Nexus Operation? 

A Standalone Nexus Operation is a top-level [Nexus Operation Execution](/nexus/operations) started
directly by a [Client](/encyclopedia/temporal-sdks#temporal-client), without using a caller
Workflow. Instead of calling a Nexus Operation from within a Workflow Definition, you execute it
directly from a Nexus Client created from the Temporal SDK Client and bound to a
[Nexus Endpoint](/nexus/endpoints) and Service.
