Yes, once you have your API link, you don't need VPN or proxy the next time you play. You can just go online, click play game at the top-right.

This is also a way to get your API link if you don't have one yet. Login to the DMM game as usual (via VPN) and you'll automatically be redirected to the extension that contains your API link (where, as mentioned, you can also play forever).
