after a while, steam will block you from making more requests and this can cause issues.
i looked at your code and saw:

        if response["success"] == True:
            return response
        return None

please change
if response["success"] == True
to
if response.get("success", None) == True
is Response is None you can't use a key on it. So instead you do .get("success", None) which defaults to None instead of throwing an Error.
This is a 2 second fix and prevents users from having to use a try/except

You could add new features, such as the quantity of items in the market and the lowest request to buy an item in the market, if possible.

when i tried to run the sample code as it is, also i tried to print it, but it always returns none, i might be doing something wrong, but i haven't just figured it out what wrong.

I'm very new to python and it's been very few days since I started coding in python.
I'm actively investing and interested in tracking the price on a day-to-day basis. I tried google sheets with importXML features but it didn't work well. I stumbled across this library and started using this.

Everything works well, only when I try the following line of code, it fails. It's even working with knives having * in the name.

market = Prices('INR')
print(market.get_price("Boston 2018 Returning Challengers (Holo/Foil)",730))

Let me know if I'm doing anything wrong or if I have to do something to get this work.
I've tried using \ to see if escape characters help, but it failed.

Any help here will be a great learning opportunity for me. Thanks.

I ran

from steam_community_market import Market, AppID

market = Market("USD")

item = "AK-47 | Redline (Field Tested)"

market.get_lowest_price(item, AppID.CSGO)


market.get_volume(item, 730)

This threw:
