Именно в этом смысл протокола oEmbed.
oEmbed - это формат, позволяющий встроенное представление URL-адреса на сторонних сайтах. Простой API позволяет веб-сайту отображать встроенный контент (например, фотографии или видео), когда пользователь публикует ссылку на этот ресурс, без необходимости непосредственного анализа ресурса.
