KeyCaptcha API support

What are "KeyCAPTCHA" challenges?

They`re challenges that typically require the user to solve a simple puzzle.

For your convenience, we implemented support for KeyCaptcha API. If your software works with it, and supports minimal configuration, you should be able to decode KeyCaptchas using Death By Captcha in no time.

  • KeyCaptcha API: Provided a site url and KeyCaptcha site key, the API returns a token that you will use to submit the form in the page with the KeyCaptcha challenge.

Pricing

For the time being, price is $2.89/1K Keycaptcha challenges correctly solved. You will not be billed for KeyCaptcha reported as incorrectly solved. Note that this pricing applies to KeyCaptcha challenges only, so only customers using this specific API will be charged said rate.

KeyCaptcha API FAQ:

What`s the KeyCaptcha API URL?

To use the KeyCaptcha API you will have to send a HTTP POST Request to http://api.dbcapi.me/api/captcha

What are the POST parameters for the KeyCaptcha API?

  • username: Your DBC account username
  • password: Your DBC account password
  • type=10: Type 10 specifies this is a KeyCaptcha API
  • keycaptcha_params=json(payload): the data to access the KeyCaptcha challenge
  • json payload structure:
    • proxy: your proxy url and credentials (if any).Examples:
    • proxytype: your proxy connection protocol. For supported proxy types refer to Which proxy types are supported?. Example:
      • HTTP
    • s_s_c_user_id: Java Script variable used by KeyCaptcha

      Example:

      You need to locate this param in the webpage source. You can find it inside a "script" HTML tag.

      • 15
    • s_s_c_session_id: Java Script variable used by KeyCaptcha

      Example:

      You need to locate this param in the webpage source. You can find it inside a "script" HTML tag.

      • 8c8ad5a784ec913bec04aa63d923ccb0
    • s_s_c_web_server_sign: Java Script variable used by KeyCaptcha

      Example:

      You need to locate this param in the webpage source. You can find it inside a "script" HTML tag.

      • ccf7c202576b6b47b6c3d4584ebbd8de-pz-
    • s_s_c_web_server_sign: Java Script variable used by KeyCaptcha

      Example:

      You need to locate this param in the webpage source. You can find it inside a "script" HTML tag.

      • 063b44822f295c6697bccd42aec65dd6
    • pageurl: the url of the page with the KeyCaptcha challenges. This url has to include the path in which the KeyCaptcha is loaded. Example: if the KeyCaptcha you want to solve is in http://test.com/path1, pageurl has to be http://test.com/path1 and not http://test.com.

    The proxy parameter is optional, but we strongly recommend to use one to prevent rejection by the provided page due to inconsistencies between the IP that solved the captcha (ours if no proxy is provided) and the IP that submitted the solution for verification (yours).


    Note: if proxy is provided, proxytype is a required parameter.

    Full example of keycaptcha_params:

    
    {
        'proxy': 'http://user:[email protected]:1234',
        'proxytype': 'HTTP',
        's_s_c_user_id': 15,
        's_s_c_session_id': '8c8ad5a784ec913bec04aa63d923ccb0',
        's_s_c_web_server_sign': 'ccf7c202576b6b47b6c3d4584ebbd8de-pz-',
        's_s_c_web_server_sign2': '063b44822f295c6697bccd42aec65dd6',
        'pageurl': 'https://testsite.com/xxx-test'
    }
                

What`s the response from the KeyCaptcha API?

The KeyCaptcha API response has the following structure. It`s valid for one use and has a 2 minute lifespan. It will be a string like the following:


"ebdb5a6bf76da6887db60ef2041ab946|9006dc725760858e4c0715b835472f22|
http://back10.keycaptcha.com/swfs/ckc/0d4d08-|
493e52c37c10c2bcdf4a00cbc9ccd1e8|1"
      

Which proxy types are supported?

Currently, only HTTP proxies are supported. Support for other types will be added in the future.
