EZTV - this will let you search for and download torrents using the EZTV api. Currently you can only download magnet links.

TPB (The Pirate Bay) - thepiratebay.org this will let you search for and download torrents using the pirate bay api. Currently you can only download magnet links. It also shows the top and recent torrents in each category: audio, video, apps etc.

LibGen - This lets you find and download books from libgen.li. The downloading isn't great - with PDF it seems like it hangs because it wont show you progress in the browser, you just need to wait and it will finish. With other formats like EPUB and MOBI at least you should see how much data has been downloaded so far.

How to use

For these scripts to work you will need to place them on a server in a country which does not restrict access to the site you want (e.g. EZTV). For example, using a free account with infinityfree.com works since it provides a PHP server in the USA.
