Bypassing Funcaptcha in 2 ways solutions

Arkose Labs introduces different types of captcha protection.
2Captcha is Arkose Labs captcha (Funcaptcha) solver.
In this article, we will look at 2 options for completing tasks for the user.
The instructions describe the process of interacting with API.

Details about the tasks

Funcaptcha has two main options:

  1. Standard grid captcha
  2. funcaptcha_compare

Grid captcha type:

In this case, the user is offered a set of images divided into sections with numeric labels. He must select an image corresponding to the provided text description.

Example: On the left side there is an image with the number 8, and on the right there is a set of images with various objects. The user needs to select an image where the sum of the object values is 8.
Image example:

Funcaptcha_compare type:

In this version, there is also an image at the bottom, but this time with a set of icons. At the top of the image, there is a set of icons with different permutations. Users must match the icons on the left side with those on the top right side.

Example: Fruit icons are shown, and on the top on the right side are the same icons, but in a different sequence. The user needs to match each icon.
Image example:

How to solve a captcha using the API?

1. Get the image of captcha​

To solve the captcha in this way, you need to transfer the ENTIRE image.

  • Open the "Network" tab in your browser's developer tools.
  • Find a request with a captcha image, this is a request with a URL
    https://client-api.arkoselabs.com/rtig/image...
  • In the section 'Headers', you will find a field containing the URL of the captcha image.
  • Open the image and save it, after you can convert it to base64.

2. Get the text instruction

  • Find the element with instructions for the captcha
var taskElement = document.querySelector('.sc-1io4bok-0');
  • Get text from element
var taskText = taskElement.textContent || taskElement.innerText;

Important: The textinstructions must be in English!

Response example

From the received response, we take the captcha ID and, using it, request a response with a GET request of the form:

For APIv1

https://2captcha.com/res.php?

For APIv2

https://api.2captcha.com/getTaskResult

The result contains the number of clicks that need to be clicked, for example:

{
  "status": 1,
  "request": "click:3"
}

Using the Response

The result of the request is represented by a set of coordinates in the "click" format:2". The number indicates how many times you should click on the arrow to successfully solve the captcha.
