- Now you can start writing code. Let's start by importing the necessary components:
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using Zennolab.CapMonsterCloud;
using Zennolab.CapMonsterCloud.Requests;
namespace CaptchaSolver
class Program
{
static async Task Main(string[] args)
{
string API_KEY = "YOUR_API_KEY";
string SITE_KEY = "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-";
string WEBSITE_URL = "https://www.google.com/recaptcha/api2/demo";
await SolveCaptcha(API_KEY, SITE_KEY, WEBSITE_URL);
Console.WriteLine("Press any key to exit...");
Console.ReadKey();
}
static async Task SolveCaptcha(string API_KEY, string SITE_KEY, string WEBSITE_URL)
{
var clientOptions = new ClientOptions
{
ClientKey = API_KEY
};
var cmCloudClient = CapMonsterCloudClientFactory.Create(clientOptions);
var options = new ChromeOptions();
options.AddArgument("--no-sandbox");
options.AddArgument("--disable-dev-shm-usage");
using (var driver = new ChromeDriver(options))
{
try
{
driver.Navigate().GoToUrl(WEBSITE_URL);
Console.WriteLine("Page open, reCAPTCHA solving...");
var task = new RecaptchaV2ProxylessRequest
{
WebsiteUrl = WEBSITE_URL,
WebsiteKey = SITE_KEY
};
var result = await cmCloudClient.SolveAsync(task);
Console.WriteLine("Task is solved!");
((IJavaScriptExecutor)driver).ExecuteScript("var element = document.getElementById('g-recaptcha-response');" +
$"element.textContent = '{result.Solution.Value}';");
driver.FindElement(By.Id("recaptcha-demo-submit")).Click();
Console.WriteLine("Verification completed!");
}
catch (Exception ex)
{
Console.WriteLine($"Ошибка: {ex.Message}");
}
await Task.Delay(5000);
driver.Quit();
}
}
}

Code explanation:
class Program: Declaring the Program class.
static async Task Main(string[] args): The Main method of the application, which will be executed when the program starts. This method is asynchronous and uses Task to perform asynchronous operations.
string API_KEY = "YOUR_API_KEY";: Defining an API_KEY variable containing the API key for CapMonster Cloud.
string SITE_KEY = "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-";: Defining the SITE_KEY variable containing the site key for reCAPTCHA.
string WEBSITE_URL = "https://www.google.com/recaptcha/api2/demo";: Defining a WEBSITE_URL variable containing the URL of the reCAPTCHA web page.
await SolveCaptcha(API_KEY, SITE_KEY, WEBSITE_URL);: Calling the SolveCaptcha method, passing the keys and URL as arguments.
Console.WriteLine("Press any key to exit...");: Printing a message to the console.
Console.ReadKey();: Waiting for the user to press a key before ending the program.
SolveCaptcha function performs a reCAPTCHA solution on the specified web page.
var clientOptions = new ClientOptions { ClientKey = API_KEY };: Creating a ClientOptions object specifying the API key.
var cmCloudClient = CapMonsterCloudClientFactory.Create(clientOptions);: Creating a CapMonster Cloud API client with the specified options.
var options = new ChromeOptions();: Creating a ChromeOptions object to configure the Chrome browser.
options.AddArgument("--no-sandbox"); and options.AddArgument("--disable-dev-shm-usage");: Adding Chrome Browser launch arguments to improve security and reduce memory usage.
using (var driver = new ChromeDriver(options)): Creating a ChromeDriver instance to control the Chrome Browser.
driver.Navigate().GoToUrl(WEBSITE_URL);: Going to the specified URL in the browser.
var task = new RecaptchaV2ProxylessRequest { WebsiteUrl = WEBSITE_URL, WebsiteKey = SITE_KEY };: Creating a task object to solve reCAPTCHA.
var result = await cmCloudClient.SolveAsync(task);: reCAPTCHA solving using CapMonster Cloud API.
((IJavaScriptExecutor)driver).ExecuteScript("var element = document.getElementById('g-recaptcha-response');" + $"element.textContent = '{result.Solution.Value}';");: Executing JavaScript code to insert a reCAPTCHA solution into a page.
driver.FindElement(By.Id("recaptcha-demo-submit")).Click();: Finding the button element and clicking on it to complete verification.
Console.WriteLine("Verification completed!");: Displays a message about verification completion.
catch (Exception ex) { Console.WriteLine($"Error: {ex.Message}"); }: Handling possible exceptions and displaying an error message.
await Task.Delay(5000);: Waiting 5 seconds.
driver.Quit();: Closing the browser.
Let's run our script. If you did everything correctly, the result will be the successful execution of the program:
