Introduction

reCAPTCHA is a captcha service provided by Ace Data Cloud, based on the Google reCAPTCHA solution. Through the unified API of Ace Data Cloud, you can quickly integrate reCAPTCHA using JavaScript to achieve functionalities such as reCAPTCHA v2 Token, reCAPTCHA v2 recognition, reCAPTCHA v3 Token, 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 reCAPTCHA API is: 
POST https://api.acedata.cloud/captcha/token/recaptcha2
Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/captcha/token/recaptcha2", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "website_key": "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
  "website_url": "https://www.google.com/recaptcha/api2/demo"
}),
});

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 callreCAPTCHA(data) {
  const response = await fetch("https://api.acedata.cloud/captcha/token/recaptcha2", {
    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();
}
