Friendly Captcha recognition and bypass service

Launched a Friendly Captcha bypass service.

Article describes the process of interaction with the API

What is Friendly Captcha

What is Friendly Captcha: Friendly Captcha is a system designed to protect websites from bots. Key feature - works silently. Unlike traditional captchas that require user interaction like solving puzzles or clicking boxes, Friendly Captcha works passively in the background. Users don't even notice it happening.

How Friendly Captcha works

  • Proof-of-work: Friendly Captcha sends a complex cryptographic puzzle to the user's device that is automatically solved in the background, using the device's resources.
  • No user action: Unlike other captchas that require clicking or typing, Friendly Captcha works entirely in the background without any user input.

How to bypass Friendly Captcha

It is not easy to bypass Friendly Captcha, but the bypass process can be automated using API.

The bypass process is as follows:

  • The customer sends a set of required parameters from the landing page to the automatic solution service;
  • The task is performed by a worker of the service, after which the answer is returned in the form of a token, which must be entered into the appropriate field for bypassing.

To use the API, one must register on site. After activating the profile, the customer receives the API key and can start working with the service.

The process of interaction with API is described below and code samples in the most popular programming languages are given.
