oh and of course as this is merged, we have to add the price api url to the environment

Now that I think of it, I actually don't think it needs to be there because this is tailored to a specific API and it was already in the open before: https://github.com/AlphaKretin/ygoprodeck-tag-bot/blob/master/config.json#L13

It doesn't need to be secret, but it's consistent with how we handle our other APIs/URLs. I would also object to hardcoding it in the command file, as it may be used later to add price data to card embeds.

Wouldn't we move the entire getPrice function out then, which contains the URL?

...True. In that case, if that's how you want to do it I don't necessarily object, but I do lightly prefer the current state.

[kevinlul]

Let's inline it. It's consistent with /yugipedia and /ygoprodeck.
