MiniMax H3 uses the model ID minimax/h3/image-to-video. MiniMax H3 / Hailuo-03 preview integration using Video Generation V2.
1. Calling the API
Send requests to https://api.higgsfield.ai/minimax/h3/image-to-video 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 | Yes | — | Prompt. Minimum length: 1. |
duration | integer | No | 5 | Duration. Minimum: 5. Maximum: 15. |
image_url | string | Yes | — | First frame URL. |
resolution | string | No | "2K" | Resolution. Options: 2K. |
aspect_ratio | string | No | "auto" | Aspect ratio. Options: auto, adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16. |
end_image_url | string | No | — | Last frame URL. |
aigc_watermark | boolean | No | false | AIGC watermark. |
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(
"minimax/h3/image-to-video",
{
input: {
"prompt": "A cinematic scene at sunset",
"duration": 5,
"image_url": "https://example.com/input.jpg",
"resolution": "2K",
"aspect_ratio": "auto",
"aigc_watermark": false
},
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)
