How to solve hCAPTCHA?

To solve hCaptcha using the CAPTCHAs.IO API web service, you'll need to follow a series of steps to interact with their API. Here’s a step-by-step guide:

Step 1: Sign Up for CAPTCHAs.IO

First, you need to create an account on https://captchas.io and obtain your API key.

Step 2: Integrate the API in Your Code

Below is an example of how you can integrate the CAPTCHAs.IO API to solve hCaptcha using Python. This involves sending the captcha details to the API and then retrieving the solution.

Required Libraries

You'll need `requests` library to make HTTP requests. If you don't have it installed, you can install it using:


pip install requests

Example Code

Here’s a Python script that demonstrates how to solve hCaptcha using the CAPTCHAs.IO API:


import requests
import time

# Your API key from CAPTCHAs.IO
API_KEY = 'YOUR_API_KEY'

# The site URL and the site key of the hCaptcha
site_url = 'https://example.com'
site_key = 'SITE_KEY_FROM_TARGET_WEBSITE'

# Step 1: Submit the captcha solving request
submit_url = 'https://api.captchas.io/in.php'
data = {
    'key': API_KEY,
    'method': 'hcaptcha',
    'sitekey': site_key,
    'pageurl': site_url,
    'json': 1
}

response = requests.post(submit_url, data=data)
captcha_id = response.json().get('request')

if response.json().get('status') == 1:
    print(f"Captcha ID: {captcha_id}")

    # Step 2: Poll for the captcha result
    result_url = 'https://api.captchas.io/res.php'
    result_data = {
        'key': API_KEY,
        'action': 'get',
        'id': captcha_id,
        'json': 1
    }

    # Wait for a few seconds before polling
    time.sleep(20)

    while True:
        result_response = requests.get(result_url, params=result_data)
        result_json = result_response.json()

        if result_json.get('status') == 1:
            captcha_solution = result_json.get('request')
            print(f"Captcha Solved: {captcha_solution}")
            break
        elif result_json.get('request') in ['CAPCHA_NOT_READY', 'ERROR_NO_SLOT_AVAILABLE']:
            print("Captcha not ready, waiting...")
            time.sleep(5)
        else:
            print(f"Error: {result_json.get('request')}")
            break
else:
    print(f"Error: {response.json().get('request')}")

Key Points

Here’s a Python script that demonstrates how to solve hCaptcha using the CAPTCHAs.IO API:

Submit the captcha solving request: You need to provide the `API_KEY`, the `site_key` (which is the public key of the hCaptcha), and the `site_url` (the URL of the website where the captcha is located).
Poll for the captcha solution: After submitting the request, you need to wait for a while and then keep polling the API to check if the captcha has been solved. The polling interval can be adjusted based on your needs.

Error Handling

Handle errors gracefully by checking the response status and message.
Implement retries and exponential backoff in case of transient issues.

Ethical Considerations

Make sure your use of captcha solving services complies with legal and ethical standards. Unauthorized use of such services can lead to legal consequences and is often against the terms of service of many websites. Always ensure you have the right to use automated tools on the target website.

By following this guide, you should be able to integrate the CAPTCHAs.IO API to solve hCaptcha programmatically in your applications.
