                    Upsolve API key, generated under Account → Developer
                    settings in the Upsolve Hub. Keys are user-scoped: pass
                    organizationId alongside the key to select which org to act
                    on.
                  examples:
                    - up_embed_************
                organizationId:
                  description: >-
                    Your Upsolve organization's UUID — the org that owns the API
                    key and project. This is NOT a project organization: do not
                    pass a value registered via /projects/register-organization,
                    and do not pass an `externalId` (only
                    `projectOrganizationId` accepts those). Omit it when using
                    an org-bound API key — the org is read from the key and any
                    value sent here is ignored. Required only for user-scoped
                    API keys (created under Account → Developer settings) and
                    for the Supabase JWT path, where the org is ambiguous and
                    membership is verified against it.

                    The data connection the workspace reads. Omit it to create a
                    workspace with no database: it answers through its connected
                    tools (MCP servers, APIs) and can be given a connection
                    later with change-connection.
