Code samples

import time, requests

API = "https://unlock-api.com"
KEY = "YOUR_API_KEY"

task = requests.post(f"{API}/createTask", json={
    "clientKey": KEY,
    "task": {
      "type": "RecaptchaV2EnterpriseTaskProxyless",
      "websiteURL": "https://example.com/login",
      "websiteKey": "6LcR_RsTAAAAAFJR_5ZdbQd0SMxL7yIDmSXH1-lo"
    }
}).json()
if task["errorId"]:
    raise SystemExit(task["errorCode"])

for _ in range(60):   # 60 x 5 s = the 5 minute task limit
    time.sleep(5)
    r = requests.post(f"{API}/getTaskResult", json={"clientKey": KEY, "taskId": task["taskId"]}).json()
    if r["errorId"]:
        raise SystemExit(f"{r['errorCode']}: {r.get('errorDescription', '')}")   # failed tasks are refunded
    if r["status"] == "ready":
        print(r["solution"]["gRecaptchaResponse"])
        break
else:
    raise SystemExit("timed out")

curl -s "https://unlock-api.com/res.php?key=YOUR_API_KEY&action=get&id=1001&json=1"
