Kling 3.0 Pro API — frequently asked questions
How do I use the Kling 3.0 Pro API?
Install the official Node.js (npm install getimg-ai) or Python (pip install getimg) SDK, or call the endpoint directly over HTTP from any client.
Make a POST request to /v2/videos/generations with your API key and a JSON body containing the model ID (kling-3) and a prompt. The API returns a request ID. Poll the status endpoint until the video is ready.
See the API documentation for the full parameter reference.
Which SDK should I use?
Use getimg-ai for Node.js and TypeScript projects, and getimg for Python. Both wrap the same REST API with typed inputs, retries, and built-in polling for video generations.
For other languages — Go, Rust, Java, Ruby, PHP — call the HTTP endpoints directly. Every example on this page includes a cURL snippet you can port to any HTTP client.

Kling 3.0 Pro supports the following resolutions: 1080p, 720p, 4K across 2 aspect ratios (16:9, 9:16). Videos can be 3 to 15 seconds long.

Does Kling 3.0 Pro support reference images?
Yes. Kling 3.0 Pro accepts up to 1 last frame and up to 1 first frame. Reference images guide the generation toward a specific style, composition, or subject. See the example above.
