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": "GeeTestTaskV4",
    "websiteURL": "https://example.com/login",
    "captchaId": "e392e1d7fd421dc63325744d5a2b9c73",

    "proxyAddress": "proxy.example.com",
    "proxyPort": 8080,

}

# 1. create the task: its price is held, not charged
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":
        print(result["solution"])
        break
else:
    raise TimeoutError("the task was not solved in time")

Tips#

  • Find captchaId in the initGeetest4 call or in the captcha_id parameter of the load request.
  • Send captcha_id, lot_number, pass_token, gen_time and captcha_output the way the page sends them after its own check.
  • GeeTestTask and GeeTestTaskProxyless with "version": 4 are accepted too and solved as v4.
  • Submit the token through the same proxy and with the same userAgent as in the task. See Proxies.
