MTCaptcha Task

Create a task

POST https://api.nocaptchaai.com/createTask

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "MTCaptchaTask",
    "websiteURL": "https://example.com",
    "websiteKey": "YOUR_WEBSITE_KEY"
  }

The API returns a taskId:

{ "errorId": 0, "status": "idle", "taskId": "CFQ2yP5DOL" }

Get the result

Poll POST https://api.nocaptchaai.com/getTaskResult until status is ready:

{ "clientKey": "YOUR_API_KEY", "taskId": "CFQ2yP5DOL" }

{
  "errorId": 0,
  "status": "ready",
  "solution": { "token": "0.WdWV79pV71mHDjQ...." }
}

# pip install requests
import requests, time

API_KEY = "YOUR_API_KEY"
BASE = "https://api.nocaptchaai.com"

task = requests.post(f"{BASE}/createTask", json={

while True:
    time.sleep(2)
    res = requests.post(f"{BASE}/getTaskResult", json={"clientKey": API_KEY, "taskId": task_id}).json()
    if res.get("status") == "ready":
        print(res["solution"]["token"]); break
