New Geetest API support

What are "Geetest" challenges?

They`re challenges that typically require the user to align and click on certain images.

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

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

Pricing

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

Geetest API FAQ:

What`s the Geetest API URL?

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

What are the POST parameters for the Geetest v3 API?

  • username: Your DBC account username
  • password: Your DBC account password
  • type=8: Type 8 specifies this is a Geetest API
  • geetest_params=json(payload): the data to access the geetest challenge
  • json payload structure:
    • proxy: your proxy url and credentials (if any).Examples:
      • http://127.0.0.1:3128
      • http://user:password@127.0.0.1:3128
    • proxytype: your proxy connection protocol. For supported proxy types refer to Which proxy types are supported?. Example:
      • HTTP
    • gt: Value of gt parameter you found on target website.

      Example:

      • 022397c99c9f646f6477822485f30404
    • challenge: Value of challenge parameter you found on target website.

      Example:

      • 38c0168576e204c23a4863a16202cac9
    • pageurl: the url of the page with the Geetest challenges. This url has to include the path in which the Geetest is loaded. Example: if the Geetest you want to solve is in http://test.com/path1, pageurl has to be http://test.com/path1 and not http://test.com.

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

    Full example of geetest_params:

    
    {
      "proxy": "http://user:password@127.0.0.1:1234",
      "proxytype": "HTTP",
      "gt": "022397c99c9f646f6477822485f30404",
      "challenge": "4c95da9e91b49a980a3b79cd7506f12b",
      "pageurl": "https://testsite.com/xxx-test"
    }
                

What are the POST parameters for the Geetest v4 API?

  • username: Your DBC account username
  • password: Your DBC account password
  • type=9: Type 9 specifies this is a Geetest API
  • geetest_params=json(payload): the data to access the geetest challenge
  • json payload structure:
    • proxy: your proxy url and credentials (if any).Examples:
      • http://127.0.0.1:3128
      • http://user:password@127.0.0.1:3128
    • proxytype: your proxy connection protocol. For supported proxy types refer to Which proxy types are supported?. Example:
      • HTTP
    • captcha_id: Value of captcha_id parameter you found on target website.

      Example:

      • fcd636b4514bf7ac4143922550b3008b
    • pageurl: the url of the page with the Geetest challenges. This url has to include the path in which the Geetest is loaded. Example: if the Geetest you want to solve is in http://test.com/path1, pageurl has to be http://test.com/path1 and not http://test.com.

    Full example of geetest_params:

    
    {
      "proxy": "http://user:password@127.0.0.1:1234",
      "proxytype": "HTTP",
      "captcha_id": "fcd636b4514bf7ac4143922550b3008b",
      "pageurl": "https://testsite.com/xxx-test"
    }
                

What`s the response from the Geetest v3 API?

    The Geetest 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:
                  
    {
      "challenge": "4c95da9e91b49a980a3b79cd7506f12b",
      "validate": "6496091eb0fb5a83fef98829d034128b",
      "seccode": "6496091eb0fb5a83fef98829d034128b|jordan"
    }

    }
                    
                  

Which proxy types are supported?

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