Introduction

Seedance is an AI video service provided by Ace Data Cloud, featuring ByteDance’s Seedance video generation model. Through the unified API of Ace Data Cloud, you can quickly integrate Seedance using JavaScript to achieve text-to-video, image-to-video, audio generation, and multiple resolution functionalities.

​
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 for calling the Seedance API is: 
POST https://api.acedata.cloud/seedance/videos
This example uses the doubao-seedance-1-0-pro-250528 model.
Available models include: doubao-seedance-1-5-pro-251215, doubao-seedance-1-0-pro-250528, doubao-seedance-1-0-pro-fast-251015. Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/seedance/videos", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "model": "doubao-seedance-1-0-pro-250528",
  "content": [
    {
      "type": "text",
      "text": "A kitten yawning --rs 720p --rt 16:9 --dur 5"
    }
  ]
}),
});

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 this into a reusable function: 
async function callSeedance(data) {
  const response = await fetch("https://api.acedata.cloud/seedance/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();
}
