Legacy/outdated Recaptcha API support

What`s "Legacy/outdated reCAPTCHA/noCAPTCHA"?

Exist a legacy/outdated reCAPTCHA challenges that typically require the user to identify and click on certain images. They`re not to be confused with traditional word/number reCAPTCHAs (those have no images).

For your convinience, we implemented support for Legacy/Outdated Recaptcha API. If your software works with it, and supports minimal configuration, you should be able to decode captchas using Death by Captcha in no time.

We provide two different types of Legacy/Outdated Recaptcha API:

  • Coordinates API: Provided a screenshot, the API returns a group of coordinates to click.
  • Image Group API: Provided a group of (base64-encoded) images, the API returns the indexes of the images to click.

Pricing

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

Image upload restrictions.

Image file size is limited to less than 180 KB. When the image will be encoded in base64, the size should be lower than 120 KB. The supported image formats are JPG, PNG, GIF and BMP.

Coordinates API FAQ:

What`s the Coordinates API URL?

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

What are the POST parameters for the Coordinates API?

These are:

  • username: Your DBC account username
  • password: Your DBC account password
  • captchafile: a Base64 encoded or Multipart file contents with a valid Legacy/Outdated Recaptcha screenshot
  • type=2: Type 2 specifies this is a Legacy/Outdated Recaptcha Coordinates API
What`s the response from the Coordinates API?

captcha: id of the provided captcha, if the text field is null, you will have to pool the url http://api.dbcapi.me/api/captcha/captcha_id until it becomes available

is_correct: (0 or 1) specifying if the captcha was marked as incorrect or unreadable

text: a json-like nested list, with all the coordinates (x, y) to click relative to the image, for example:

    [[23.21, 82.11]]

where the X coordinate is 23.21 and the Y coordinate is 82.11

Image Group API FAQ:

What`s the Image Group API URL?

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

What are the POST parameters for the Image Group API?

These are:

  • username: Your DBC account username
  • password: Your DBC account password
  • captchafile: the Base64 encoded file/image contents with the valid Legacy/Outdated Recaptcha.
  • banner: the Base64 encoded banner image (the example image that appears on the upper right)
  • banner_text: the banner text (the text that appears on the upper left)
  • type=3: Type 3 specifies this is a Legacy/Outdated Recaptcha Image Group API
  • grid: Optional grid parameter specifies what grid individual images in captcha are aligned to (string, width+"x"+height, Ex.: "2x4", if images aligned to 4 rows with 2 images in each. If not supplied, dbc will attempt to autodetect the grid.
What`s the response from the Image Group API?

captcha: id of the provided captcha, if the text field is null, you will have to pool the url http://api.dbcapi.me/api/captcha/captcha_id until it becomes available

is_correct:(0 or 1) specifying if the captcha was marked as incorrect or unreadable

text: a json-like list of the index for each image that should be clicked. for example:

    [1, 4, 6]

where the images that should be clicked are the first, the fourth and the six, counting from left to right and up to bottom

Using IMAGE GROUP API with api clients:

Usage code examples for COORDINATES API and IMAGE GROUP API:

1) Send your image:

Please note we are using type="2" for CAPTCHA COORDINATES API.


    curl --header 'Expect: ' -F username=your_username_here \
                             -F password=your_password_here \
                             -F captchafile=@'your_captcha_filename.jpg' \
                             -F type='2' http://api.dbcapi.me/api/captcha
    

OR:

Please note we are using type="3" for CAPTCHA IMAGE GROUP API.


    curl --header 'Expect: ' -F username=your_username_here \
                             -F password=your_password_here \
                             -F captchafile=@'your_captcha_filename.jpg' \
                             -F banner=@'your_banner_filename.jpg' \
                             -F banner_text=banner_text_here  \
                             -F type='3' http://api.dbcapi.me/api/captcha
    

Or, if you are supplying grid info (height x width). In this example grid 4x2 is used, you should specify it according to uploaded image. If you wont supply grid parameter, dbc would attempt to autodetect proper grid.


    curl --header 'Expect: ' -F username=your_username_here \
                             -F password=your_password_here \
                             -F captchafile=@'your_captcha_filename.jpg' \
                             -F banner=@'your_banner_filename.jpg' \
                             -F banner_text=banner_text_here  \
                             -F type='3' http://api.dbcapi.me/api/captcha
                             -F grid=4x2
    

Result is an url_encoded data including the respective CAPTCHA_ID:

    'status=0&captcha=CAPTCHA_ID&text=&is_correct=1'

2) Pulling captcha coordinates: take the given CAPTCHA_ID and make a request like this:

curl -H "Accept: application/json" \
    http://api.dbcapi.me/api/captcha/CAPTCHA_ID

Result is a json-string where the field "text" includes the respective coords:

'{"status": 0, "captcha": 2911096,
  "is_correct": true, "text": "[[57,240],[156,335]"}'

Status: OK
