Computed Column (or other) to check if URL is not 404 error

Is there any column (I cannot find one) that would check if a url is valid? Meaning checks if a URL has content on it or if it results in a 404 error? My exact use case is, having a collection of links to things for sale (on other websites), and when the item is no longer available (i.e. 404), I automatically stop displaying that rows content. Thank you!

I havent tried, but maybe new Get Web Page Source

column can help
