Kling 3.0 uses the model ID kling-video/v3/motion-control/std. Kling 3.0 Motion Control (Standard) generates videos by animating a source image according to the motion in a provided video. Users can control character orientation and choose to retain the original video's sound for customized video creation.
1. Calling the API
Send requests to https://api.higgsfield.ai/kling-video/v3/motion-control/std with a JSON body matching the parameters below.
Install
Install an official server-side SDK. cURL needs no package.
npm install @higgsfield/clientSetup
Keep credentials in server-side environment variables. The SDKs accept the same KEY_ID:KEY_SECRET value under their documented variable names.
export HF_CREDENTIALS="YOUR_KEY_ID:YOUR_KEY_SECRET" # TypeScript
export HF_KEY="YOUR_KEY_ID:YOUR_KEY_SECRET" # Python and cURLRequest parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
prompt | string | No | "" | Prompt. |
image_url | string | Yes | — | Image URL. |
video_url | string | Yes | — | Video URL. |
keep_original_sound | string | No | "yes" | Keep original sound. Options: yes, no. |
character_orientation | string | No | "video" | Generate the orientation of the characters in the video, which can be selected to match the image or the video. Options: image, video. |
2. Authentication
The official SDKs read credentials from the server environment and send the required Authorization: Key KEY_ID:KEY_SECRET header.
API Key
Never expose the secret in browser-side code or commit it to source control. The TypeScript SDK is server-side only. For direct HTTP calls, use:
Authorization: Key $HF_KEY3. Queue
subscribe submits the asynchronous request and waits for a terminal result. The TypeScript SDK polls automatically when withPolling: true; the Python SDK's synchronous subscribe call also waits. A completed request returns the generated file in the video field.
Submit and wait
import { config, higgsfield } from "@higgsfield/client/v2";
config({
credentials: process.env.HF_CREDENTIALS,
});
const result = await higgsfield.subscribe(
"kling-video/v3/motion-control/std",
{
input: {
"prompt": "",
"image_url": "https://example.com/input.jpg",
"video_url": "https://example.com/input.mp4",
"keep_original_sound": "yes",
"character_orientation": "video"
},
withPolling: true,
},
);
console.log(result);Explicit lifecycle control
Use the Python SDK when a worker needs explicit status, result, or cancellation control for an existing request. The TypeScript v2 client currently exposes automatic polling through subscribe.
import higgsfield_client
request_id = "{request_id}"
status = higgsfield_client.status(request_id=request_id)
result = higgsfield_client.result(request_id=request_id)
higgsfield_client.cancel(request_id=request_id)
