Introduction

Kling is an AI video service provided by Ace Data Cloud, featuring the Kuaishou Ling video generation model. Through the unified API of Ace Data Cloud, you can quickly integrate Kling using JavaScript to achieve text-to-video, image-to-video, video continuation, multiple durations, multiple aspect ratios, and other features.

​
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 Kling API is: 
POST https://api.acedata.cloud/kling/videos
This example uses the kling-v2-5-turbo model.
Available models include: kling-v1, kling-v1-6, kling-v2-master, kling-v2-1-master, kling-v2-5-turbo, kling-video-o1. Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/kling/videos", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "action": "text2video",
  "prompt": "A white cat walking in the snow",
  "model": "kling-v2-5-turbo",
  "duration": 5,
  "aspect_ratio": "16:9"
}),
});

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