Route::any('captcha-test', function() {
    if (request()->getMethod() == 'POST') {
        $rules = ['captcha' => 'required|captcha'];
        $validator = validator()->make(request()->all(), $rules);
        if ($validator->fails()) {
            echo '<p style="color: #ff0000;">Incorrect!</p>';
        } else {
            echo '<p style="color: #00ff30;">Matched :)</p>';
        }
    }
 
    $form = '<form method="post" action="captcha-test">';
    $form .= '<input type="hidden" name="_token" value="' . csrf_token() . '">';
    $form .= '<p>' . captcha_img() . '</p>';
    $form .= '<p><input type="text" name="captcha"></p>';
    $form .= '<p><button type="submit" name="check">Check</button></p>';
    $form .= '</form>';
    return $form;

Detailed Example in Laravel way view files

//register.blade.php
<img src="{{ captcha_src() }}" alt="captcha">
    <div class="mt-2"></div>
    <input
        type="text" name="captcha" class="form-control @error('captcha') is-invalid @enderror" placeholder="Please Insert Captch"
        >

controller files

Validator::make($input, [
    'name' => ['required', 'string', 'max:255'],
    'email' => [
        'required',
        'string',
        'email',
        'max:255',
        Rule::unique(User::class),
    ],
    'password' => $this->passwordRules(),
    'captcha' => 'required|captcha'
])->validate();

Stateless Mode:

You get key and img from this url http://localhost/captcha/api/math and verify the captcha using this method:

//key is the one that you got from json response
// fix validator
// $rules = ['captcha' => 'required|captcha_api:'. request('key')];
$rules = ['captcha' => 'required|captcha_api:'. request('key') . ',math'];
$validator = validator()->make(request()->all(), $rules);
if ($validator->fails()) {
    return response()->json([
        'message' => 'invalid captcha',
    ]);
 
} else {
    //do the job
}
