📦 Installation

pip install capmonstercloudclient

🚀 Quick Start & Usage Examples

1. Asynchronous reCAPTCHA v2 Solving

import asyncio
from capmonstercloudclient import CapMonsterClient, ClientOptions
from capmonstercloudclient.requests import RecaptchaV2Request

# Initialize client with your API key from dashboard
options = ClientOptions(api_key="YOUR_CAPMONSTER_API_KEY")
client = CapMonsterClient(options=options)

async def main():
    # Build the task payload
    request = RecaptchaV2Request(
        websiteUrl="[https://lessons.zennolab.com/captchas/recaptcha/v2_simple.php?level=high](https://lessons.zennolab.com/captchas/recaptcha/v2_simple.php?level=high)",
        websiteKey="6Lcg7CMUAAAAANphynKgn9YAgA4tQ2KI_iqRyTwd"
    )
    
    # Send task and receive token
    result = await client.solve_captcha(request)
    print("reCAPTCHA Token:", result.get("gRecaptchaResponse"))

if __name__ == "__main__":
    asyncio.run(main())

2. Browser Automation (Playwright + Cloudflare Turnstile)

import asyncio
from playwright.async_api import async_playwright
from capmonstercloudclient import CapMonsterClient, ClientOptions
from capmonstercloudclient.requests import TurnstileRequest

options = ClientOptions(api_key="YOUR_CAPMONSTER_API_KEY")
client = CapMonsterClient(options=options)

async def run_scraper():
    # Solve Turnstile challenge via CapMonster Cloud
    turnstile_req = TurnstileRequest(
        websiteURL="[https://target-website.com/login](https://target-website.com/login)",
        websiteKey="0x4AAAAAAABnPIDnK2k_e-2"
    )
    solution = await client.solve_captcha(turnstile_req)
    token = solution.get("token")

    # Inject token into Playwright browser session
    async with async_playwright() as p:
        browser = await p.chromium.launch(headless=False)
        page = await browser.new_page()
        await page.goto("[https://target-website.com/login](https://target-website.com/login)")
        
        await page.evaluate(f'document.querySelector("[name=cf-turnstile-response]").value = "{token}";')
        await page.click("#submit-button")
        await browser.close()

if __name__ == "__main__":
    asyncio.run(run_scraper())

🔄 Migrating from 2Captcha or Capsolver

Already use 2Captcha or Capsolver in your scraper or bot? Replace only the solver call and keep the rest of your parser unchanged. CapMonster Cloud follows the same flow: send the website URL and sitekey, receive the token.

Migration from 2Captcha (2captcha-python)

# Before: 2Captcha
from twocaptcha import TwoCaptcha

solver = TwoCaptcha("YOUR_2CAPTCHA_API_KEY")
result = solver.recaptcha(
    sitekey="YOUR_SITE_KEY",
    url="[https://target-website.com/page-with-recaptcha](https://target-website.com/page-with-recaptcha)",
)
token = result["code"]

# After: CapMonster Cloud
import asyncio
from capmonstercloudclient import CapMonsterClient, ClientOptions
from capmonstercloudclient.requests import RecaptchaV2Request

client = CapMonsterClient(options=ClientOptions(api_key="YOUR_CAPMONSTER_API_KEY"))

async def solve():
    result = await client.solve_captcha(RecaptchaV2Request(
        websiteUrl="[https://target-website.com/page-with-recaptcha](https://target-website.com/page-with-recaptcha)",
        websiteKey="YOUR_SITE_KEY",
    ))
    return result.get("gRecaptchaResponse")

token = asyncio.run(solve())

Migration from Capsolver (capsolver-python)

# Before: Capsolver
import capsolver

capsolver.api_key = "YOUR_CAPSOLVER_API_KEY"
solution = capsolver.solve({
    "type": "ReCaptchaV2TaskProxyLess",
    "websiteURL": "[https://target-website.com/page-with-recaptcha](https://target-website.com/page-with-recaptcha)",
    "websiteKey": "YOUR_SITE_KEY",
})
token = solution["gRecaptchaResponse"]

The "After" code is the same CapMonster Cloud snippet as above: only the client, the API key and the request class change, the rest of your scraper stays the same. If you use an async framework, call await client.solve_captcha(...) directly instead of asyncio.run.

Keep existing 2Captcha-based software

Software that already speaks the 2Captcha API can work with CapMonster Cloud without code changes. See the guide for connecting other services' APIs.

🛠️ How It Works

[ Script / Scraper ]
         │
         ▼
[ Extract sitekey & website URL ]
         │
         ▼
[ CapMonsterClient API ] ──► POST createTask to [https://api.capmonster.cloud](https://api.capmonster.cloud)
         │
         ▼
[ Neural Network Processing ] ──► Poll getTaskResult (300ms - 6s)
         │
         ▼
[ Receive Token & Autosubmit ] ──► Complete bypass

⚙️ Best Practices

• Token Expiration: Most tokens (reCAPTCHA, Turnstile) remain valid for 120 seconds. Inject and submit the solution immediately after receiving the response.
• Proxy Usage: For custom tasks and strict protections, use the same proxy in your scraping session and the CapMonster task payload.
• Balance Monitoring: Ensure your account balance remains positive in the Dashboard.
