Integrate with Wayback machine

[simonsan]

I think it could be useful to check back with Wayback machine (web.archive.org) before deleting a broken bookmark completely. It might be even worth to rewrite the bookmark then, if the page is existing there.

yes, please. I do this manually with any links that I think are "retired". I also add "(Archive)" at the end of the bookmark text to signify it is not a current link. It would be great if this feature could also optionally append a text string to bookmarks re-written to web.archive.org links.

URLs can be tested for a 200 by replacing the initial URL with https://web.archive.org/web/<URL>. The date is not needed, the aforementioned URL directs to the latest snapshot stored. I agree that an addition of (Archive) would be nice.

There is also an API:
https://archive.org/help/wayback_api.php

with an endpoint http://archive.org/wayback/available?url=<URL>

with the following responses:

No archived snapshot:

{"archived_snapshots":{}}

At least one archived snapshot:

{
    "archived_snapshots": {
        "closest": {
            "available": true,
            "url": "http://web.archive.org/web/20130919044612/http://example.com/",
            "timestamp": "20130919044612",
            "status": "200"
        }
    }
}
