-## remote_services (list\[dict])

-Configure connections to remote unshackle REST API servers to access services running on other instances.

-Each entry requires:

-  - url: "https://remote-unshackle.example.com"
-    api_key: "your_api_key_here"
-    name: "Remote US Server"
-  - url: "https://remote-unshackle-eu.example.com"
-    api_key: "another_api_key"
-    name: "Remote EU Server"
-```
-
-**Note**: The remote unshackle instances must have the REST API enabled and running. Services from all
-configured remote servers will be available alongside your local services.
