New Tencent Captcha API support
What are "Tencent Captcha" challenges?
They`re challenges that typically require the user to align and click on certain images.
For your convenience, we implemented support for Tencent Captcha API. If your software works with it, and supports minimal configuration, you should be able to decode tencent captchas using Death By Captcha in no time.
- Tencent captcha API: Provided a site url and tencent captcha appid, the API returns a token that you will use to submit the form in the page with the Tencent captcha challenge.
Pricing
For the time being, price is $2.89/1K Tencent captcha challenges correctly solved. You will not be billed for tencent captcha reported as incorrectly solved. Note that this pricing applies to new Tencent captcha challenges only, so only customers using this specific API will be charged said rate.
Tencent Captcha API FAQ:
- What`s the Tencent Captcha API URL?
-
To use the Tencent 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 Tencent Captcha API?
-
- username: Your DBC account username
- password: Your DBC account password
- type=23: Type 23 specifies this is a Tencent Captcha API
- tencent_params=json(payload): the data to access the Tencent captcha 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
-
appid: the tencent captcha appid of the website with the tencent captcha.
Example:
- 2044554539
You need to locate appid of Tencent Captcha. You can locate tencent captcha`s button element and check the value of data-appid parameter.
- pageurl: the url of the page with the Tencent captcha challenges. This url has to include the path in which the tencent captcha is loaded. Example: if the Tencent captcha 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 tencent_params:
{ 'proxy': 'http://user:password@127.0.0.1:1234', 'proxytype': 'HTTP', 'appid': '2044554539', 'pageurl': 'https://testsite.com/xxx-test' } - What`s the response from the Tencent Captcha API?
-
The Tencent Captcha 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:
{ "appid": "85773405", "ret": 0, "ticket": "tr0344YjOGfuidofFOohyWS_y6tJKiqVPIdFWlVaQouJobradjs-o-BjeassM31GUIFHgfIOGFD877*", "randstr": "YUNM" } - Which proxy types are supported?
-
Currently, only HTTP proxies are supported. Support for other types will be added in the future.
