Introduction

Suno is an AI audio service provided by Ace Data Cloud for AI music generation. Through the unified API of Ace Data Cloud, you can quickly integrate Suno using JavaScript to achieve features such as text-to-music generation, custom lyrics, song continuation, covers, vocal separation, and lyric generation.

​
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 Suno API is: 
POST https://api.acedata.cloud/suno/audios
This example uses the chirp-v5 model.
Available models include: chirp-v5, v4-5-plus, v4-5, v4, v3-5. Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/suno/audios", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "action": "generate",
  "prompt": "A cheerful pop song about summer vacation",
  "model": "chirp-v5",
  "custom": false
}),
});

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 the call into a reusable function: 
async function callSuno(data) {
  const response = await fetch("https://api.acedata.cloud/suno/audios", {
    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();
}
