                    The model name to use for generation. Required field.


                    - Must be `kling/v2-1-master-image-to-video` for this
                    endpoint
                  example: kling/v2-1-master-image-to-video
                callBackUrl:

                    The URL to receive generation task completion updates.
                    Optional but recommended for production use.


                    - System will POST task status and results to this URL when
                    generation completes

                    - Callback includes generated content URLs and task
                    information

                    - Your callback endpoint should accept POST requests with
                    JSON payload containing results

                    - Alternatively, use the Get Task Details endpoint to poll
                    task status
