These operations describe the runtime source of this publication. Cloud forwards remote operations through its authenticated runtime endpoint. Host-only operations are unavailable through that relay.

This route catalog describes transport and availability. It does not declare request or response object schemas. Use the SDK and the authoring guides for the supported developer journey.
