How to Solve CAPTCHA Challenges Using Python Requests

"Frustrating captcha..."

1. Why CAPTCHA Solving Matters

The eternal struggle - CAPTCHAs try to tell humans and bots apart

While CAPTCHAs protect websites from spam, they can block legitimate automation for:

• Research Projects: Academic and market research often require large-scale data collection from websites.
• Accessibility Tools: Tools designed to assist users with disabilities might need to navigate CAPTCHAs to provide content.
• Data Migration Scripts: When transferring data between systems, automated scripts may encounter CAPTCHAs.
• Academic Research: Scholars collecting data for studies on internet trends, user behavior, or technology adoption.
• Price Comparison and Market Analysis: Scraping product prices from e-commerce sites to analyze market trends.
• E-commerce Product Scraping: Monitoring competitors' websites to track product availability and pricing.
• Ad Verification: Ensuring that online advertisements are displayed correctly and not manipulated by bots.
• SEO and Website Monitoring: Checking website performance, uptime, and content changes in an automated manner.
• Social Media Data Collection: Aggregating public posts or trends from social platforms for sentiment analysis.
• Cybersecurity Research: Analyzing potential vulnerabilities or testing the robustness of security measures.
• Content Aggregation: Automatically collecting articles or blog posts for news aggregation services.

How the CAPTCHA solving process works

Complete code walkthrough:

# pip install requests
import requests
import time
 
# TODO: set your config
api_key = "YOUR_API_KEY"  # your api key of capsolver
site_key = "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_kl-"  # site key of your target site
site_url = ""  # page url of your target site
 
 
def capsolver():
    payload = {
        "clientKey": api_key,
        "task": {
            "type": 'ReCaptchaV3TaskProxyLess',
            "websiteKey": site_key,
            "websiteURL": site_url,
            "pageAction": "login",
        }
    }
    res = requests.post("https://api.capsolver.com/createTask", json=payload)
    resp = res.json()
    task_id = resp.get("taskId")
    if not task_id:
        print("Failed to create task:", res.text)
        return
    print(f"Got taskId: {task_id} / Getting result...")
 
    while True:
        time.sleep(1)  # delay
        payload = {"clientKey": api_key, "taskId": task_id}
        res = requests.post("https://api.capsolver.com/getTaskResult", json=payload)
        resp = res.json()
        status = resp.get("status")
        if status == "ready":
            return resp.get("solution", {}).get('gRecaptchaResponse')
        if status == "failed" or resp.get("errorId"):
            print("Solve failed! response:", res.text)
            return
 
 
token = capsolver()
