[Userscript]: WaniKani Ultimate Timeline

The error in your post above is because you included the <> around your API key. It should just be in quotes.

But that’s not necessary now anyway. Open Framework can fetch your key on its own now.

Do this first (in the Javascript console, while on the Wanikani Dashboard):

delete localStorage.apiv2_key

Then refresh.

(Of course, as always, Open Framework needs to be the first script to run. See [here] if you’re not sure what I mean.)
