API = "https://neurocaptcha.com"
KEY = os.environ["API_KEY"]


def call(method, payload):
    data = requests.post(f"{API}/{method}", json={"clientKey": KEY, **payload}, timeout=30).json()
    if data.get("errorId"):
        raise RuntimeError(f'{data["errorCode"]}: {data.get("errorDescription", "")}')
    return data


task = {
    "type": "RecaptchaV2Task",
    "websiteURL": "https://www.google.com/recaptcha/api2/demo",

task_id = call("createTask", {"task": task})["taskId"]

# 2. poll every 2 s; a failed task raises with its error code and costs nothing
deadline = time.time() + 300
while time.time() < deadline:
    time.sleep(2)
    result = call("getTaskResult", {"taskId": task_id})
    if result["status"] == "ready":

        break
else:
    raise TimeoutError("the task was not solved in time")

  "errorId": 0,
  "status": "ready",

}

Tips#

Find websiteKey in the data-sitekey attribute, or in the k= parameter of the anchor request (DevTools → Network).
No checkbox, only a badge in the corner? Set isInvisible: true.
Put the token into textarea#g-recaptcha-response (or g-recaptcha-response form field) and call the widget callback if the page has data-callback.
Submit the token through the same proxy and with the same userAgent as in the task. See Proxies.
