New Cutcaptcha API support

What are "Cutcaptcha" challenges?

They`re challenges where you have to drag an drop pieces of an image to complete the image.

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

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

Pricing

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

Cutcaptcha API FAQ:

What`s the Cutcaptcha API URL?

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

What are the POST parameters for the Cutcaptcha API?

  • username: Your DBC account username
  • password: Your DBC account password
  • type=19: Type 19 specifies this is a Cutcaptcha API
  • cutcaptcha_params=json(payload): the data to access the cutcaptcha 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
    • apikey: the cutcaptcha api key of the website with the cutcaptcha.

      Example:

      • SAs61IAI

      You need to locate api key of Cutcaptcha. You can locate cutcaptcha`s iframe element and check the value of data-apikey parameter. Or you could check the name of javascript file included on the page.

    • miserykey: the cutcaptcha misery key of the website with the cutcaptcha.

      Example:

      • 56a9e9b989aa8cf99e0cea28d4b4678b84fa7a4e

      You need to locate misery key of Cutcaptcha. You can locate the value of CUTCAPTCHA_MISERY_KEY variable defined on the page.

    • pageurl: the url of the page with the Cutcaptcha challenges. This url has to include the path in which the Cutcaptcha is loaded. Example: if the Cutcaptcha 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 cutcaptcha_params:

    
    {
        'proxy': 'http://user:password@127.0.0.1:1234',
        'proxytype': 'HTTP',
        'apikey': 'SAs61IAI',
        'miserykey': '56a9e9b989aa8cf99e0cea28d4b4678b84fa7a4e',
        'pageurl': 'https://testsite.com/xxx-test'
    }
                

What`s the response from the Cutcaptcha API?

The Cutcaptcha 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:


"pO10d8ABZCjrDztF9Ik9JbEhwxmufnQn"
      

Which proxy types are supported?

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