Run a turn through the gateway and block until it finishes, returning the completed execution with its result. Pass id = your conversation_id to start or continue a conversation; omit it to start a new one (the returned execution’s id becomes the conversation_id). Re-invoking a conversation that is already running preempts the in-flight turn. For fast time-to-first-token and live progress, prefer the streaming variant. See the Agent Gateway overview for the full conversation model.
