Is there a way to return only current highest order quantity instead of all orders like
https://api.guildwars2.com/v2/commerce/listings?ids=19684 would give?
also not https://api.guildwars2.com/v2/commerce/prices/19684 as this gives total supply

No. The ?top parameter comes kind of close, but it sorts by price, not quantity.
