Magento2 : How to send a request for a page and get the page status?

Question

I want to check if the status of the page is not 200, then add it to the array along with the status and send it to the mail at the end of the script

I can't finish the code, tell me how to implement it. My code stops working on the line $this->curl->get($url);

<?php

namespace Modules\Test\Cron;

class Test
{
    protected $curl;

    private $logger;

    public function __construct(
        \Psr\Log\LoggerInterface $logger,
        \Magento\Framework\HTTP\Client\Curl $curl
    ) {
        $this->logger = $logger;
        $this->curl = $curl;
    }

    public function execute(): void
    {
        $urls = [
            'http://example.com/one',
            'http://example.com/two',
            'http://example.com/three'
        ];

        $problemUrls = [];

        $this->curl->setCredentials('basicLogin', 'basicPass');

        foreach ($urls as $url) {
            try {
                $this->curl->get($url);
                $response = $this->curl->getHeaders();
                if ($response === 404) {
                    array_push($problemUrls, $url);
                }

                if (!empty($problemUrls)) {
                    mail('test@gmail.com', 'test@gmail.com', var_export($problemUrls, true));
                }
            }
            catch (\Exception $e) {
                $this->logger->critical('Error Curl', ['exception' => $e]);
            }
        }
    }
}
