# The URL of the page where the challenge is presented
site_url = "https://www.google.com/recaptcha/api2/demo"

def solve_flight_captcha():
    # Define the task payload for the CapSolver API
    payload = {
        "clientKey": api_key,
        "task": {
            "type": 'ReCaptchaV2TaskProxyLess',
            "websiteKey": site_key,
            "websiteURL": site_url
        }
    }
    
    # Create a new task on the CapSolver platform
    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")
        return
    
    # Poll the API until the solution is ready
    while True:
        time.sleep(1)
        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":
            print("CAPTCHA solved successfully")
            return resp.get("solution", {}).get('gRecaptchaResponse')
        
        if status == "failed" or resp.get("errorId"):
            print("Task failed or encountered an error")
            return None
