New Hcaptcha API support

What are "Hcaptcha" challenges?

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

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

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

Pricing

For the time being, price is $3.99/1K Hcaptcha challenges correctly solved. You will not be billed for Hcaptcha reported as incorrectly solved. Note that this pricing applies to new Hcaptcha challenges only, so only customers using this specific API will be charged said rate.

Hcaptcha API FAQ:

What`s the Hcaptcha API URL?

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

What are the POST parameters for the Hcaptcha API?

  • username: Your DBC account username
  • password: Your DBC account password
  • type=7: Type 7 specifies this is a Hcaptcha API
  • hcaptcha_params=json(payload): the data to access the hcaptcha 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
    • sitekey: the hcaptcha site key of the website with the hcaptcha.

      Example:

      • 56489210-0c02-58c0-00e5-1763b63dc9d4

      You need to locate site key of HCaptcha. You can locate hcaptcha`s div element and check the value of data-sitekey parameter.

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

    
    {
        'proxy': 'http://user:password@127.0.0.1:1234',
        'proxytype': 'HTTP',
        'sitekey': '56489210-0c02-58c0-00e5-1763b63dc9d4',
        'pageurl': 'https://testsite.com/xxx-test'
    }
                

    Full example of hcaptcha_params: with optional rqdata

    
    {
        'proxy': 'http://user:password@127.0.0.1:1234',
        'proxytype': 'HTTP',
        'sitekey': '56489210-0c02-58c0-00e5-1763b63dc9d4',
        'pageurl': 'https://testsite.com/xxx-test'
        'rqdata': 'rqdata-parameter-from-site'
    }
                

What`s the response from the Hcaptcha API?

The Hcaptcha 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:

Which proxy types are supported?

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