When used in the WordPress Custom REST API endpoint you can do it like this:

function customrestapiplugin_getpost( $slug ) {
    $args = [
        'name' => $slug['slug'],
        'post_type' => 'post'
    ];

    $post = get_posts($args);
    
    $data[$i]['id'] = $post[0]->ID;
        $data['title'] = $post[0]->post_title;
        $data['content'] = $post[0]->post_content;
        $data['excerpt'] = $post[0]->post_excerpt;
        $data['slug'] = $post[0]->post_name;
        $data['date'] = $post[0]->post_date;
        $data['link'] = get_permalink($post[0]->ID);
        $data['author'] = get_the_author_meta('display_name', $post[0]->post_author);
        $data['featured_image']['thumbnail'] = get_the_post_thumbnail_url($post[0]->ID, 'thumbnail');
        $data['featured_image']['medium'] = get_the_post_thumbnail_url($post[0]->ID, 'medium');
        $data['featured_image']['large'] = get_the_post_thumbnail_url($post[0]->ID, 'large');

    return $data;
}

For those who are looking for a seamless solution on how to get an author of a post in WordPress, this is another lightweight method.

global $wpdb;

    $post_id = 12; // your post id
    
    $post_author_id = (int) $wpdb->get_var( $wpdb->prepare( "SELECT post_author FROM {$wpdb->posts} WHERE ID = %d ", $post_id ) );
    
    $author =  new WP_User( $post_author_id );
    
    $display_name = $author->display_name;
    
    $avartar = get_avatar( $post_author_id, 30 ); // get_avatar( userid, size )
    
    $author_url = get_author_posts_url( $post_author_id );
