Wan 3.0 Prime — API reference

Wan 3.0 Prime Image to Video uses the model ID alibaba/wan-3.0-prime/image-to-video. Generate videos from a starting image with Wan 3.0 Prime.

1. Calling the API

Send requests to https://api.higgsfield.ai/alibaba/wan-3.0-prime/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/client

Setup

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 cURL

Request parameters

Parameter	Type	Required	Default	Description
`seed`	`integer`	No	`—`	Seed. Minimum: 0. Maximum: 2147483647.
`prompt`	`string`	Yes	`—`	Prompt.
`duration`	`integer`	No	`5`	2-30 seconds. Minimum: 2. Maximum: 30.
`image_url`	`string`	Yes	`—`	First Frame.
`resolution`	`string`	No	`"1080p"`	Resolution. Options: 480p, 720p, 1080p.
`aspect_ratio`	`string`	No	`"adaptive"`	Aspect Ratio. Options: 16:9, 4:3, 1:1, 3:4, 9:16, adaptive.
`end_image_url`	`string`	No	`—`	Last Frame.
`generate_audio`	`boolean`	No	`true`	Sound.
`enable_thinking`	`boolean`	No	`false`	Deep Thinking.

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_KEY

3. 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(
  "alibaba/wan-3.0-prime/image-to-video",
  {
    input: {
      "prompt": "A cinematic scene at sunset",
      "duration": 5,
      "image_url": "https://example.com/input.jpg",
      "resolution": "1080p",
      "aspect_ratio": "adaptive",
      "generate_audio": true,
      "enable_thinking": 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)
