Introduction

hCaptcha is a captcha service provided by Ace Data Cloud. The hCaptcha solution allows you to quickly integrate hCaptcha using Python through the unified API of Ace Data Cloud, enabling functionalities such as hCaptcha Token acquisition and hCaptcha image recognition.

​
Prerequisites

  • Have an Ace Data Cloud account and obtain an API Token
  • Python 3.7 or above environment
  • Install the requests library: pip install requests

​
Basic Usage

The main endpoint to call the hCaptcha API is: 
POST https://api.acedata.cloud/captcha/token/hcaptcha
Complete Python code example: 
import requests

url = "https://api.acedata.cloud/captcha/token/hcaptcha"
headers = {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json"
}
data = {
    "website_key": "a5f74b19-9e45-40e0-b45d-47ff91b7a6c2",
    "website_url": "https://accounts.hcaptcha.com/demo"
}

response = requests.post(url, headers=headers, json=data)
result = response.json()
print(result)
Please replace YOUR_API_TOKEN with the actual Token you obtained from the Ace Data Cloud platform.

​
Response Handling

After a successful call, the API returns data in JSON format. It is recommended to check the HTTP status code: 
if response.status_code == 200:
    result = response.json()
    print("Call succeeded:", result)
else:
    print(f"Call failed, status code: {response.status_code}")
    print(response.text)

​
Advanced Usage

For APIs that support asynchronous tasks, you can obtain results via a callback URL: 
data['callback_url'] = 'https://your-server.com/callback'
response = requests.post(url, headers=headers, json=data)
# Results will be pushed to your server through the callback URL

​
Error Handling

Common error codes:
Status CodeDescription
401Authentication failed, please check API Token
403Insufficient balance or no access rights
429Request rate limit exceeded
500Internal server error
