Can I buy a WoW Token without a subscription?

I'm curious to know, is it possible to purchase a WoW Token without having an active subscription to the game? As someone who's interested in exploring the cryptocurrency aspect of World of Warcraft, I'm wondering if there's a way to acquire the Token without needing to maintain a paid subscription status. Could you please elaborate on the possibilities and any potential limitations or requirements that might be involved in such a transaction?
