A WayBackMachine API I made.
I made this because I wanted an API for the "save page now" function and one didn't already exist.
I probably need to add some usage docs...
You could use it to make a client side web crawler-bot that saves temporary posts (web pages that you know will expire or change).
You could also use it to use the WayBackMachine as a weird sort of cdn system but that's not recommended because WayBackMachine is often slow, it's best used for long term non-delete-able storage as it's meant to be.
You could also use it to make a search engine that indexes all the webpages on the WayBackMachine, which would be awesome.
