NetEase Captcha Token Solving

Solve NetEase (Yidun) captcha challenges programmatically. NetEase Captcha is a popular captcha system developed by NetEase, widely used on Chinese websites and applications.

What is NetEase Captcha?

NetEase Captcha (易盾) is a captcha protection system developed by NetEase. It's commonly used on Chinese websites and applications for bot protection. There's also an Enterprise version with additional parameters. The solution returns a token for form submission.

Captcha Type

Use the following captcha type identifier in your API requests:

"type": "NETEASE_CAPTCHA_TOKEN"

Finding Captcha Parameters

To solve NetEase Captcha, you need to find the parameters from network requests:

// Open Developer Tools, activate the captcha, go to Network tab
Enterprise Version Parameters

If you find captchaId, captchaHash, and captchaTimestamp parameters in network requests, this indicates the Enterprise version. You should also provide jsLibUrl (JS file path) and apiServerSubdomain for Enterprise captchas.

Python Example

Python 
import requests
import time

def solve_netease_captcha(site_url, site_key, api_key, user_agent=None):
    # Step 1: Create task
    payload = {
        'auth': {'token': api_key},
        'context': {'source': 'api', 'version': '1.0.0'},
        'captcha': {
            'type': 'NETEASE_CAPTCHA_TOKEN',
            'metadata': {
                'siteUrl': site_url,
                'siteKey': site_key
            },
            'payload': {}
        }
    }

    if user_agent:
        payload['captcha']['payload']['userAgent'] = user_agent

    create_response = requests.post(
        'https://solver-api.mydisct.com/createTask',
        headers={
            'Content-Type': 'application/json',
            'apikey': api_key
        },
        json=payload
    )

    create_data = create_response.json()
    if not create_data['success']:
        raise Exception(create_data['error']['message'])

    task_id = create_data['task']['id']
    print(f'Task created: {task_id}')

    # Step 2: Poll for result
    while True:
        time.sleep(5)
        result_response = requests.post(
            'https://solver-api.mydisct.com/fetchResult',
            headers={'Content-Type': 'application/json', 'apikey': api_key},
            json={'taskId': task_id}
        )
        result_data = result_response.json()

        if result_data['task']['status'] == 'completed':
            return result_data['task']['result']['token']
        elif result_data['task']['status'] == 'failed':
            raise Exception('Solving failed')

        print('Still processing...')

# Usage
token = solve_netease_captcha(
    site_url='https://www.example.com',
    site_key='6cw0f0485d5d46auacf9b735d20218a5',
    api_key='YOUR_API_KEY',
    user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'
)

print(f'NetEase token: {token}')

cURL Example

cURL 
# Create task
curl -X POST https://solver-api.mydisct.com/createTask \
  -H "Content-Type: application/json" \
  -H "apikey: YOUR_API_KEY" \
  -d '{
    "auth": {"token": "YOUR_API_KEY"},

# Fetch result (replace TASK_ID with actual task ID)
curl -X POST https://solver-api.mydisct.com/fetchResult \
  -H "Content-Type: application/json" \
  -H "apikey: YOUR_API_KEY" \
  -d '{"taskId": "TASK_ID"}'

Best Practices

Recommendations
  • Use a valid Windows User-Agent string for better success rates
  • For Enterprise version, always provide jsLibUrl and apiServerSubdomain
  • Enterprise parameters (captchaId, captchaHash, captchaTimestamp) are short-lived, extract and use them immediately
  • The siteKey (id parameter) is typically a 32-character alphanumeric string
  • Check network requests starting with "get?referer=" or "check?referer=" to find parameters
  • Using a proxy is optional but may be required for some websites
