 Examples of solving captchas using the Python programming language, and the [2captcha-python] and [Selenium] libraries.
 
-This repository contains examples of automation of solving the most popular types of captcha, such as [reCAPTCHA][recaptcha-v2-demo], [Cloudflare Turnstile][cloudflare-turnstile], [normal captcha][normal-captcha-demo], [hCaptcha][hcaptcha-demo] and others. Selenium library is used for browser automation in the examples. The [2Captcha] service is used for solving captchas, therefore, for the correct work of the examples it is necessary to have an account in the [captcha solving service][2Captcha] service with a positive balance, or you can try to test it using [sandbox] mode to solve captchas manually.

  Also, for `proxy` examples to work correctly, you need to have your own `proxy` and set it in the example code. The examples of captcha automation solving use captchas located on the [captchas demo pages](https://2captcha.com/demo).
 
 We have our own proxies that we can offer you. [Buy residential proxies] to avoid restrictions and blocks. [Quick start].

 #### Cloudflare Turnstile
 
 Token-based Cloudflare Turnstile solution.
 
-This example demonstrates how to bypass the Cloudflare Turnstile CAPTCHA located on the page https://2captcha.com/demo/cloudflare-turnstile. The Selenium library is used to automate browser actions and retrieve CAPTCHA parameters. To solve this type of Cloudflare CAPTCHA, it is necessary to send parameters such as pageurl and sitekey to the [2Captcha API](https://2captcha.com/2captcha-api#turnstile). After receiving the solution result (token), the script automatically uses the received answer on the page.

+This example demonstrates how to bypass the Cloudflare Challenge located on the page https://2captcha.com/demo/cloudflare-turnstile-challenge. The Selenium library is used to automate browser actions and retrieve CAPTCHA parameters. To solve this type of Cloudflare CAPTCHA, it is necessary to send parameters such as `pageurl`,`sitekey`, `action`, `data`, `pagedata`, `useragent` to the [2Captcha API](https://2captcha.com/2captcha-api#turnstile). After receiving the solution result (token), the script automatically uses the received answer on the page.

+> [!NOTE]
+> When a web page first loads, some JavaScript functions and objects (such as `window.turnstile`) may already be initialized and executed. If the interception script is launched too late, this may lead to the fact that the necessary parameters will already be lost, or the script simply will not have time to intercept the right moment. Refreshing the page ensures that everything starts from scratch and you trigger the interception at the right time.
