New Geetest API support

What`s "new Geetest"?

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 $$2.99/1K 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

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.

The proxy parameter is optional, but we strongly recommend to use one to prevent token 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 Geetest for verification (yours).
