Request Body

{
  "email": "[email protected]",
  "prompt": "A majestic mountain landscape with snow-capped peaks and flowing rivers",
  "negative_prompt": "people, buildings, text, low quality",
  "duration": "10",
  "model_name": "kling-v2-1-master",
  "aspect_ratio": "16:9",
  "replyUrl": "https://your-callback-url.com/webhook",
  "replyRef": "your-reference-id"
}

email is optional when only one account configured.
However, if you have multiple accounts configured, this parameter becomes required.
prompt is required (unless using multi-shot), the text description of the video to generate. Maximum length: 2500 characters. Cannot be used together with multi-shot parameters (shot_N_prompt/shot_N_duration).
negative_prompt is optional, what not to include in the generated video. Models 2.5, 2.6, and 3.0 do not support this parameter.
Maximum length: 2500 characters.
cfg_scale is optional, guidance scale for text-to-video generation. Models 2.x do not support this parameter.
Range: 0 to 1. Default: 0.5.
duration is optional, length of the video in seconds. Cannot be used together with multi-shot parameters (shot_N_prompt/shot_N_duration). Supported values depend on model_name:

Model Supported Durations

kling-v3-0 3, 4, 5 (default), 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

kling-v2-6, v2-5, v2-1-master, v1-6, v1-5 5 (default), 10
model_name is optional, the AI model version to use. Supported values: kling-v3-0, kling-v2-6, kling-v2-5, kling-v2-1-master, kling-v1-6 (default), kling-v1-5.
aspect_ratio is optional, the video aspect ratio. Supported values: 16:9 (default), 9:16, 1:1.
mode is optional, quality level. Models 2.1 Master and 2.5 only support pro mode. Supported values: std (standard, default) or pro (higher quality, slower generation). Model 2.6 supports both modes, but pro is required when enable_audio is true.
enable_audio is optional, add sound effects (Native Audio for models 2.6 and 3.0). Supported values: false (default) or true. Model 2.6 with enable_audio: true requires mode: pro. Model 3.0 defaults to audio enabled; set enable_audio: false to disable.
shot_1_prompt through shot_6_prompt are optional, per-shot text prompts for multi-shot storytelling (v3 only). Maximum length: 2500 characters per shot. Minimum 2 shots required. Cannot be used together with prompt or duration.
shot_1_duration through shot_6_duration are optional, per-shot duration in seconds. Each shot must have both prompt and duration. Total duration must be 3-15 seconds. Shots must be sequential with no gaps (e.g. shot_1 + shot_2, not shot_1 + shot_3).
maxJobs is optional, range from 1 to 50.
Specifies the maximum number of concurrent jobs.
replyUrl is optional, a callback URL to receive generation progress and result.
See GET /tasks/task_id for response model.
replyRef is optional, a reference identifier for the callback.

500 Internal Server Error

Kling uses a 500 response to indicate moderation and other issues with the input. It may be hard to separate actual 500 errors from moderation errors, so use the error field text and your best judgement to tell them apart, since the message field most often has very generic and perhaps misleading text.
```
{
  "error": "The content you uploaded appears to violate the community guidelines. (CM_EXT.POther)",
  "message": "Service busy (CM_EXT.POther)"
}
```

When successful, the response includes a task ID which can be used to check the status using GET /tasks/task_id.
