 The `--no-buffer` flag ensures curl displays events as they arrive instead of buffering them.
 
 **Note:** The `state` object can include:
 - `question`: The question to answer (required)
-- `use_citations`: Enable citations in deep ask responses (optional, deep ask only)
+- `max_iterations`: Maximum research iterations (optional, defaults to config)
+- `confidence_threshold`: Confidence threshold for early termination (optional, defaults to config)
 
 **Response:** Server-Sent Events stream with AG-UI protocol events:
 - `RUN_STARTED` - Graph execution started
