ParseHub + CaptchaAI: No-Code Scraping with CAPTCHA Solving

ParseHub is a visual scraping tool that struggles with CAPTCHAs. Here's how to use CaptchaAI to pre-solve CAPTCHAs and feed authenticated sessions into ParseHub.

The Challenge

ParseHub's visual selector can't interact with CAPTCHAs:

Issue	Impact
reCAPTCHA blocks scraping	ParseHub can't click checkboxes
Login CAPTCHAs	Can't authenticate
Rate-limit CAPTCHAs	Extraction stops mid-run
Cloudflare challenges	Page never loads data

Solution: Pre-Authentication Script

import requests
import time
import json


def pre_authenticate(api_key, login_url, sitekey, credentials):
    """
    Solve CAPTCHA, authenticate, and export cookies for ParseHub.

    Run this script before starting your ParseHub extraction.
    """
    session = requests.Session()

    # Set realistic headers
    session.headers.update({
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) "
                       "AppleWebKit/537.36 Chrome/125.0.0.0 Safari/537.36",
    })

    # Visit login page for initial cookies
    print("1. Loading login page...")
    session.get(login_url, timeout=15)

    # Solve CAPTCHA
    print("2. Solving CAPTCHA...")
    token = solve_captcha(api_key, sitekey, login_url)
    print(f"   Token received ({len(token)} chars)")

    # Submit login
    print("3. Submitting login form...")
    resp = session.post(login_url, data={
        **credentials,
        "g-recaptcha-response": token,
    }, timeout=30)

    if resp.status_code != 200 or "error" in resp.text.lower():
        print(f"   Login may have failed (status: {resp.status_code})")
    else:
        print("   Login successful")

    # Export cookies
    cookies = {c.name: c.value for c in session.cookies}
    print(f"4. Exported {len(cookies)} cookies")

    return cookies


def solve_captcha(api_key, sitekey, pageurl):
    """Solve reCAPTCHA via CaptchaAI."""
    resp = requests.post("https://ocr.captchaai.com/in.php", data={

    result = resp.json()

Using ParseHub API with Pre-Solved Cookies

import requests

    """Start a ParseHub run with pre-authenticated cookies."""
    # Format cookies for ParseHub
    cookie_string = "; ".join(f"{k}={v}" for k, v in cookies.items())

    resp = requests.post(

        timeout=30,
    )

    if resp.status_code == 200:
        run_data = resp.json()

    resp = requests.get(
        f"https://www.parsehub.com/api/v2/runs/{run_token}/data",
        params={"api_key": api_key, "format": "json"},

    )
    return resp.json()

Scheduled Workflow

FAQ

Can ParseHub solve CAPTCHAs on its own?

ParseHub has limited CAPTCHA handling for simple image CAPTCHAs. For reCAPTCHA, Turnstile, or other modern CAPTCHAs, use CaptchaAI to pre-solve and pass cookies.
