High scores recaptcha v3 token with python#

August 07,2024

Bypassing reCAPTCHA v3 with high scores using Python and NextCaptcha involves a few steps. Here is a general guide on how to achieve this: A high-score reCAPTCHA token is essential for ensuring successful validation and bypass of the reCAPTCHA v3 challenge. reCAPTCHA v3 uses a scoring system to differentiate between human and bot traffic. The higher the score, the more likely it is that the traffic is from a legitimate user. This guide ensures that the token retrieved from NextCaptcha meets the high-score criteria, typically above 0.7, to maximize the chances of successful verification.

Set Up Python Environment:

Make sure you have Python installed. You will also need to install necessary libraries such as requests.
```
   pip install requests
```
Sign Up for NextCaptcha:
Register an account with NextCaptcha and get your API key.
Solve reCAPTCHA v3 using NextCaptcha.:
NextCaptcha provides an API to solve reCAPTCHA challenges. You need to send a request to their service, and they will return a token that can be used to bypass the CAPTCHA.
Integrate with Your Application:
Use the token provided by NextCaptcha to bypass the reCAPTCHA in your application.

Here is a Python script demonstrating this process:

import requests
 
# Your NextCaptcha API key
api_key = 'YOUR_NEXTCAPTCHA_API_KEY'
site_key = '6LcAbwIqAAAAAJvVAhSSJ8qzYsujc7kn1knmSgQX'
page_url = 'https://nextcaptcha.com/'
 
# Step 1: Send a request to NextCaptcha to solve the reCAPTCHA
captcha_request_url = 'https://api.nextcaptcha.com/createTask'
payload = {
    'clientKey': api_key,
    'task': {
        'type':'RecaptchaV3TaskProxyless',
        'websiteURL': page_url,
        'websiteKey': site_key,
        'pageAction': 'submit'
    }
}
 
response = requests.post(captcha_request_url, data=payload)
if response.status_code != 200:
    print('Failed to send request to NextCaptcha')
    exit()
 
response_data = response.json()
 
captcha_id = response_data.get('taskId')
 
# Step 2: Retrieve the solved token from NextCaptcha
retrieve_url = 'https://api.nextcaptcha.com/getTaskResult'
params = {
    'clientKey': api_key,
    'taskId': captcha_id
}
 
solution = None
while solution is None:
    time.sleep(1)  # Wait a few seconds before checking again
    response = requests.post('https://api.nextcaptcha.com/getTaskResult', data={
		  "clientKey": "api key",
		  "taskId": request_id
		})
    if response.json().get('errorId') == 0:
        solution = response.json().get('solution')
 
# The reCAPTCHA token
recaptcha_token = solution["gRecaptchaResponse"]
print(f'Successfully retrieved token: {recaptcha_token}')
 
# Step 3: Use the token in the verify API endpoint
verify_url = 'https://next.nextcaptcha.com/api/captcha-demo/recaptcha_enterprise/verify'
verify_payload = {
    'siteKey': site_key,
    'gRecaptchaResponse': token,
    'action': 'submit'
}
 
verify_response = requests.post(verify_url, json=verify_payload)
if verify_response.status_code == 200:
    print('Verification response:', verify_response.json())
else:
    print('Failed to verify token')

Integrate with Your Application#

Set Up Environment:: Ensure Python and requests library are installed.
Request Solution: Send a request to NextCaptcha with the required parameters to solve the reCAPTCHA.
Retrieve Token: Poll NextCaptcha for the solved token.
Verify Token: Send the solved token to the specified verification API endpoint.

This script will help you bypass reCAPTCHA v3 by leveraging the NextCaptcha service and the provided API details.
