Great idea, but this link doesn't really work -- it always has the same secret word, because the Wayback Machine injects some JavaScript to make the Date function return a constant date (try running `console.log(new Date())`).
The link posted by @rossy (with "id_") works fine though.
("id_" stands for "identity" and means to return the original resource without rewriting the content, see https://pywb.readthedocs.io/en/latest/manual/rewriter.html#i...)
