V3 Turbo Pro text-to-video

This documentation is valid for the following list of our models:

klingai/video-v3-turbo-pro-text-to-video
kling-video/v3/turbo/pro/text-to-video

Kling 3.0 Turbo Pro generates high-quality 1080p videos from text prompts with improved lipsync and multishot generation capabilities.

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

Now, all of our API schemas for video models use our new universal short URL — https://api.aimlapi.com/v2/video/generations. However, you can still call this model using the legacy URL that includes the vendor name.

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.
