Introduction

QR Art is an AI image service provided by Ace Data Cloud for generating AI artistic QR codes. Through the unified API of Ace Data Cloud, you can quickly integrate QR Art using JavaScript to create link QR codes, text QR codes, preset styles, custom parameters, and more.

​
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 QR Art API is: 
POST https://api.acedata.cloud/qrart/generate
Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/qrart/generate", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "type": "link",
  "content": "https://platform.acedata.cloud",
  "prompt": "sunset ocean waves",
  "preset": "neon-mech"
}),
});

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 callQRArt(data) {
  const response = await fetch("https://api.acedata.cloud/qrart/generate", {
    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();
}
