}Kling Image-to-Video
This series supports OpenAI video generation formats (see the link Video generation Sora compatible formats).
Kling 4.0 native task API. Authenticate using this site’s Bearer API Key. The request body does not require model; settings.resolution=720p uses kling-4.0, while 1080p uses kling-4.0-1080p, with 1080p as the default. After successful creation, use the returned data.id to call GET /tasks?task_ids=task ID; separate multiple IDs with commas. The returned data is an array, and the result video is available at data[].outputs[].url.
Currently supported generation scenarios include prompts, first_frame, last_frame, refer_image, and feature_video. middle_frame, base_video, element, voice, audio references, callbacks, and custom external task IDs are not supported. Non-empty options.callback_url, non-empty options.external_task_id, non-empty contents.id, and other unsupported fields will return 400. options can be omitted or passed as an empty object; watermark_info.enabled=false can also be passed. Enabling watermarks is not currently supported. Supported durations range from 4 to 30 seconds, with a default of 10 seconds; 3 seconds is not supported. For text-to-video and reference scenarios, the default aspect ratio is 16:9; explicitly specifying adaptive will return 400. For first- and last-frame scenarios, explicitly specifying settings.aspect_ratio is not accepted; the aspect ratio is determined by the dimensions of the first frame image.
For image-to-video, contents must include a non-empty prompt and first_frame, and may also include last_frame; first_frame and last_frame can each contain at most one image. The first and last frames cannot be used together with refer_image reference images or feature_video reference videos; doing so returns a 400 error. settings.aspect_ratio is not supported.

Body
A non-empty prompt and supported media must both be provided. Image-to-video generation must include first_frame. first_frame/last_frame cannot be used together with refer_image/feature_video; otherwise, a 400 error is returned. See the API documentation for quantity limits for each type of media.
