NetEase Yidun (网易易盾) is China's #2 captcha service after Tencent. It offers slider puzzles, click-in-order challenges, and icon selection. Most commercial captcha-solving services don't support Yidun — Capzy is one of the few that does.

Quick Integration

solve.py
import requests, time

API = "https://api.capzy.ai"
KEY = "capzy_your_key_here"

# Step 1: Create task
task = requests.post(f"{API}/createTask", json={
    "clientKey": KEY,
    "task": {
        "type": "YidunSliderTaskProxyLess",
        "websiteURL": "https://dun.163.com/trial/jigsaw",
        "websiteKey": "5a0e2d04ffa44caba3f740e6a8b0fa84",
        "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36"
    }
}).json()

task_id = task["taskId"]
print(f"Task created: {task_id}")

# Step 2: Poll for result
while True:
    result = requests.post(f"{API}/getTaskResult", json={
        "clientKey": KEY,
        "taskId": task_id
    }).json()

    if result["status"] == "ready":
        print("Solved!", result["solution"])
        break
    elif result["status"] == "failed":
        print("Failed:", result.get("errorDescription"))
        break

    time.sleep(1)

Using the result

use_result.py
# Step 3: Yidun — submit validate token to your backend
validate = result["solution"]["validate"]
requests.post("https://target.example.com/verify", data={"validate": validate})

1. Send Payload

Dispatch your YidunSliderTaskProxyLess to our processing cluster via the secure API endpoint.

2. Solving Engine

Capzy's proprietary solver returns the Yidun validate token for direct submission. Designed for authorized testing and automation.

3. Get Result

Poll getTaskResult for the validated token, then finalize your automated request.

Using your own proxy

Use YidunSliderTask instead of YidunSliderTaskProxyLess to route the solve through your own proxy — useful when the target site checks that the solving IP matches the submitting IP.

    }
}).json()

task_id = task["taskId"]
print(f"Task created: {task_id}")

# Step 2: Poll for result
while True:
    result = requests.post(f"{API}/getTaskResult", json={
        "clientKey": KEY,
        "taskId": task_id
    }).json()

    if result["status"] == "ready":
        print("Solved!", result["solution"])
        break
    elif result["status"] == "failed":
        print("Failed:", result.get("errorDescription"))
        break

    time.sleep(1)
