OptionalpageBest-effort upper bound on the number of results to return. Honored as an upper
bound by the shim: page_size only narrows the legacy backend's response, never
widens it, so the practical cap is min(page_size, legacy_fixed_page_size).
OptionalpagePage token from a previous response. If not provided, returns the first page.
OptionalparentThe Workspace that owns this collection of endpoints.
Format: workspaces/{workspace_id}
