The spell, Identify, requires a material component to cast that costs 100gp. The point of having that spell would be so that you do not need to find an NPC to cast that spell for you. If it goes by actual D&D rules, you should be able to use Read Magic or even a good Spellcraft check to identify scrolls, and Spellcraft can be used to identify potions.
