{
    DefaultProvider = CaptchaProvider.TwoCaptcha,
    TwoCaptchaApiKey = "key1",
    CapSolverApiKey = "key2",
    AntiCaptchaApiKey = "key3"

// Use specific provider

    provider: CaptchaProvider.CapSolver);

ASP.NET Core Integration

// Program.cs
builder.Services.AddForeverToolsCaptcha("your-api-key");

// Or with full configuration

    options.DefaultProvider = CaptchaProvider.TwoCaptcha;
    options.TwoCaptchaApiKey = "key1";
    options.CapSolverApiKey = "key2";
    options.TimeoutSeconds = 120;
});

// Or from appsettings.json
builder.Services.AddForeverToolsCaptcha(builder.Configuration);

// appsettings.json
{
  "Captcha": {
    "DefaultProvider": "TwoCaptcha",
    "TwoCaptchaApiKey": "your-key",
