Introduction

hCaptcha is a captcha service provided by Ace Data Cloud, offering hCaptcha solutions. Through the unified API of Ace Data Cloud, you can quickly integrate hCaptcha using JavaScript to achieve hCaptcha Token acquisition, hCaptcha image recognition, and other functions.

​
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 hCaptcha API is: 
POST https://api.acedata.cloud/captcha/token/hcaptcha
Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/captcha/token/hcaptcha", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "website_key": "a5f74b19-9e45-40e0-b45d-47ff91b7a6c2",
  "website_url": "https://accounts.hcaptcha.com/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 as a reusable function: 
async function callhCaptcha(data) {
  const response = await fetch("https://api.acedata.cloud/captcha/token/hcaptcha", {
    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();
}
