What is Cloudflare Challenge?

Cloudflare Challenge is a browser verification system used to protect websites, login pages, sign-up forms, checkout flows, APIs, and other sensitive endpoints from bots, abuse, and suspicious automated traffic. Instead of relying on a traditional visible CAPTCHA every time, Cloudflare Challenge analyzes browser behavior, request patterns, and security signals to determine whether a visitor should be allowed to proceed.

A professional Cloudflare Challenge solver allows automation systems to bypass Cloudflare Challenge programmatically using an API. This helps bots, scripts, and browser automation tools pass protected flows efficiently, maintain session continuity, and continue automated tasks without manual interruption.

How to Solve Cloudflare Challenge

CaptchaAI provides automated Cloudflare Challenge solving for developers and automation systems. 
Our Cloudflare Challenge solver allows you to solve Cloudflare Challenge and bypass Cloudflare Challenge verification using a simple API workflow.

Step 1: Submit the Task to CaptchaAI

Send a POST request to https://ocr.captchaai.com/in.php with method=cloudflare_challenge and your proxy:

PYTHON
import requests

response = requests.post("https://ocr.captchaai.com/in.php", data={
    'key': 'YOUR_API_KEY',
    'method': 'cloudflare_challenge',
    'pageurl': 'https://example.com/protected-page',
    'proxy': 'user:password@111.111.111.111:8080',
    'proxytype': 'HTTP',
    'json': 1
})

task_id = response.json()['request']
print(f"Task ID: {task_id}")

Step 2: Retrieve the Solution

Wait 15–20 seconds, then poll for the result using json=1 to receive the cf_clearance value and solver User-Agent:

PYTHON
import time

time.sleep(20)

while True:
    result = requests.get("https://ocr.captchaai.com/res.php", params={
        'key': 'YOUR_API_KEY',
        'action': 'get',
        'id': task_id,
        'json': 1
    }).json()

    if result['status'] == 1:
        cf_clearance = result['result']
        user_agent = result['user_agent']
        print(f"cf_clearance: {cf_clearance}")
        print(f"User-Agent: {user_agent}")
        break

    time.sleep(5)

Step 3: Use the Cookie to Access the Protected Page

Inject the cf_clearance cookie and use the exact same User-Agent and proxy as the solver:

PYTHON
import requests

session = requests.Session()

# Must use the same proxy
proxies = {'http': 'http://user:password@111.111.111.111:8080',
           'https': 'http://user:password@111.111.111.111:8080'}

session.headers.update({'User-Agent': user_agent})
session.cookies.set('cf_clearance', cf_clearance, domain='example.com')

response = session.get("https://example.com/protected-page", proxies=proxies)
print(response.status_code)

Cloudflare Challenge vs Cloudflare Turnstile

Cloudflare Challenge protects full-page access before content loads, while Cloudflare Turnstile is an embedded verification widget designed to protect specific actions such as login, signup, and form submission with less friction.

Feature Cloudflare Challenge Cloudflare Turnstile
Verification Type Full-page interstitial challenge Embedded widget challenge
Where It Appears Before the page content becomes accessible Inside forms or protected page actions
User Experience Temporarily blocks access to the full page Usually low-friction or invisible verification
What It Returns cf_clearance cookie Verification token
Required Data Page URL, proxy, and user agent Sitekey and page URL
Best For Access protection, anti-bot gating, and protected page entry Login, signup, checkout, and other form workflows

If the target page shows an embedded widget inside a form or action flow, use the Cloudflare Turnstile solver. If the site blocks the full page before content loads, use the Cloudflare Challenge solver instead.
