Introduction

Wan is an AI video service provided by Ace Data Cloud, Alibaba’s Wanxiang video generation model. Through the unified API of Ace Data Cloud, you can quickly integrate Wan using JavaScript to achieve text-to-video, image-to-video, reference video generation, and multiple resolutions.

​
Prerequisites

  • Have an Ace Data Cloud account and obtain an API Token
  • Node.js 18+ or a modern browser environment

​
Basic Usage

The main endpoint to call the Wan API is: 
POST https://api.acedata.cloud/wan/videos
This example uses the wan2.6-t2v model.
Available models include: wan2.6-t2v, wan2.6-i2v, wan2.6-r2v, wan2.6-i2v-flash. Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/wan/videos", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "action": "text2video",
  "model": "wan2.6-t2v",
  "prompt": "Astronauts shuttle from space to volcano",
  "resolution": "720P"
}),
});

const result = await response.json();
console.log(result);
Please replace YOUR_API_TOKEN with the actual token you obtained from the Ace Data Cloud platform.

​
Response Handling

It is recommended to check the response status code and handle errors: 
if (response.ok) {
  const result = await response.json();
  console.log("Call succeeded:", result);
} else {
  console.error(`Call failed, status code: ${response.status}`);
  const error = await response.text();
  console.error(error);
}

​
Node.js Wrapper

It is recommended to encapsulate it as a reusable function: 
async function callWan(data) {
  const response = await fetch("https://api.acedata.cloud/wan/videos", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.ACE_API_TOKEN}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify(data),
  });
  if (!response.ok) throw new Error(`API error: ${response.status}`);
  return response.json();
}

​
Error Handling

Common error codes:

401Authentication failed, please check API Token
403Insufficient balance or no access permission
429Request rate limit exceeded
