Getting cards hash names

[Nico31]

I am looking for an easier way to get market hash name for any card (not only cards from my inventory, or cards in a trade). I'm currently using node-steamcommunity, doing a market search for each card by name and filtering the results. But this way takes too much time when I have to search too many cards, sometimes gets me rate limited, and sometimes can't even find the card I'm looking for.

Is there any viable way for achieving this, or should I stick to my method?

Searching the market is the only way to get a list of available assets for an app, without using inventories or third-party sites.
