Gathering upgrade items from the item API

I wish to gather a list of upgrade components (item.type=UpgradeComponent) from /v2/items. Is there an efficient way to gather these items without sending an inquiry for each of the roughly 57k items in the game? I'm unable to search this forum for answers as I get "Something has gone wrong." - so I apologize if this has been answered before,

Thanks.
