[Auto Activate] Is there a way to verify multiple keys?

[steamhackor]

I have a list of keys and I want to see which keys are still available. Is there a checker or validate key program?

No, there is no checker for that. You can't check any key without activation.

Mainly for trading as well. I want to verify the key i'm selling is legit. :) or a activator that activates keylists.
