When purchasing from several bots.
Apparently most bots don't like CSGO keys?
Is there a way around this?

CS:GO Item API is down. So it is basically not something we could control.

I recommend this page for checking "CS:GO Backpack API status" and "Steam Trading API status"
http://csgolounge.com/status

If one of these or both is down, our bots won't be able to recognize CS:GO items.
