Text Captcha API support

What are "TextCaptcha" challenges?

They`re challenges that typically require the user to answer some questions.

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

  • Textcaptcha API: Provided the question, the API returns the answer that you will use to submit the form in the page with the Textcaptcha challenge.

Pricing

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

Text Captcha API FAQ:

What`s the Text Captcha API URL?

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

What are the POST parameters for the Text Captcha API?
  • username: Your DBC account username
  • password: Your DBC account password
  • type=11: Type 11 specifies this is a Text Captcha API
  • textcaptcha=: the question that needs to be answered
What`s the response from the Textcaptcha API?
