âď¸ Prerequisites
- A working proxy
- Python installed
- Capsolver API key
đ¤ Step 1: Install Necessary Packages
Execute the following commands to install the required packages:
pip install capsolver
pip install os
pip install requests
đ¨âđť Step 2: Python Code for solve Cloudflare Challenge 5s
Here's a Python sample script to accomplish the task:
# -*- coding: utf-8 -*-
import requests
import time
import tls_client
# TODO: Your api key
API_KEY = ""
proxy = ""
# TODO: Your target site url:
page_url = ""

"task": {
"type": 'AntiCloudflareTask',
"websiteURL": page_url,
"proxy": proxy,
}
}

res = requests.post(uri, json=data)
resp = res.json()
task_id = resp.get('taskId')
if not task_id:
print("no get taskId:", res.text)
return
print('created taskId:', task_id)
while True:
time.sleep(1)
data = {
"clientKey": API_KEY,
"taskId": task_id
}
response = requests.post('https://api.capsolver.com/getTaskResult', json=data)
resp = response.json()

if status == "ready":
print("successfully => ", response.text)
return resp.get('solution')

â ď¸ Change these variables
- PROXY: Update with your proxy details. The format should be http://username:password@ip:port.
- capsolver.api_key: Obtain your API key from the Capsolver Dashboard.
- PAGE_URL: Replace with the URL of the website for which you wish to solve the CloudFlare challenge.
