I would like to introduce the service that was my hobby.
Youtube video thumbnails have multiple images of different sizes. Copy and use an image URL of an appropriate size, such as when posting it on a blog.
Get and check various information attached to the image.
Get and check the Meta tag information of the page of the specified URL.
oEmbed is a standard specification that allows you to embed a web page in another site. If you enter the URL of the corresponding web page, you can access it based on the specifications of oEmbed and embed it to check the response data.
