How to Make a Call

Step-by-Step Instructions

Generating a video using this model involves sequentially calling two endpoints:

• The first one is for creating and sending a video generation task to the server (returns a generation ID).

• The second one is for requesting the generated video from the server using the generation ID received from the first endpoint. Below, you can find both corresponding API schemas.

API Schemas

Create a video generation task and send it to the server

This endpoint creates and sends a video generation task to the server — and returns its ID.

post

Body

modelstring · enumRequiredPossible values:

promptstringOptional

Text prompt for video generation. Either prompt or multi_prompt must be provided, but not both.

multi_promptstring[]Optional

List of prompts for multi-shot video generation. If provided, overrides the single prompt and divides the video into multiple shots with specified prompts and durations.

image_urlstring · uriRequired

A direct link to an online image or a Base64-encoded local image that will serve as the visual base or the first frame for the video.

tail_image_urlstring · uriOptional

A direct link to an online image or a Base64-encoded local image to be used as the last frame of the video.

durationinteger · enumOptional

The length of the output video in seconds.

Default: 5Possible values:

shot_typestring · enumOptional

The type of multi-shot video generation

Default: customizePossible values:

generate_audiobooleanOptional

Whether to generate audio for the video.

Default: true

negative_promptstringOptional

The description of elements to avoid in the generated video.

cfg_scalenumber · max: 1Optional

The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt.

providerstringOptional

Provider routing override. kling (alias klingai) runs native Kling with no fallback; fal runs the fal.ai mirror; auto (default) uses the Kling -> fal.ai fallback chain. Case-insensitive.

Example: auto

idstringRequired

The ID of the generated video.

The current status of the generation task.

Retrieve the generated video from the server

After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its id, obtained from the endpoint described above. If the video generation task status is completed, the response will include the final result — with the generated video URL and additional metadata.
