Make sure you install you have installed MegaOptim PHP library via composer.

use MegaOptim\Optimizer;

$megaoptim = new Optimizer('your-api-key');

$images = [ '/path/to/file1.jpg', '/path/to/file2.jpg' ];

$response = $megaoptim->run( $images, ['compression' => Optimizer::INTELLIGENT ] );

if( $response->isSuccessful() ) {
    foreach($response->getOptimizedFiles() as $file) {
        $file->saveAsFile('path/to/optimized-file.jpg');
    }
} else {
    foreach($response->getErrors() as $error) {
        echo $error;
    }
}
                            

First make sure you install you have installed python and pip and then run pip install megaoptim to install
