Please note: The tweaked version of this extension is available from the extension directory: Wayback Machine — PopClip Extensions
The following extension checks if an archived version of a website is available from the Wayback Machine (Wikipedia: Wayback Machine) which is run by the Internet Archive.
It copies the URL of the most recent archived version to the clipboard. The extension calls the Wayback Machine API, which is faster than other methods.
If the output URL is also to be displayed by PopClip, remove // before popclip.showText.
When holding the option key while envoking the extension, the returned URL is also opened in the browser. This makes it easier to check whether the archive version contains the desired content.
Rarely does the API incorrectly state that there is no archive version. In this case, this should be checked via Wayback Machine website.
