Get Steam Market (API) results in euro

Question

I use this URL to get 100 results at a time of CS:GO containers. I substitute {currency} for 3 and {start} for a multiple of 100, my problem is that currency=3 doesn't seem to be euro, it is about 17% off (I have to multiply received value by 0.83 to get a pretty good result):

market_url = ("https://steamcommunity.com/market/search/render/?"
    "category_730_Type%5B%5D=tag_CSGO_Type_WeaponCase"
    "&norender=1"
    "&count=100"
    "&sort_column=name"
    "&sort_dir=asc"
    "&currency={currency}"
    "&start={start}")

From what I understand:

• category_730_Type%5B%5D=tag_CSGO_Type_WeaponCase is to choose CS:GO crates
• norender=1 is to not get html
• count=100 - results per page
• sort_column=name&sort_dir=asc for ordering
• currency=3 choose euro as currency <-- doesn't work
• start=100 start at result 100

But however, I change the currency it doesn't change sell_price nor sell_price_text in response. It still prints:

(...) "sell_listings":68,"sell_price":963,"sell_price_text":"9,63€" (...) Note the €.

Do I have a typo there? Is currency even parsed on the steam part?

To be crystal clear. I would like to get the same price (in euros) as is presented on the steam market (if you have the site in euros).

EDIT: Seems impossible at the moment. If it becomes possible, please post a new answer!

Get Steam Market (API) results in euro

Unfortunately, it isn't possible. The parameter you're referring to, i.e. currency only allows for specific sub-pages to be called, e.g.:

https://steamcommunity.com/market/priceoverview/?appid=730&currency=3&market_hash_name=Fracture%20Case

(looking for the price of the Fracture Case) - returns:

{"success":true,"lowest_price":"0,39€","volume":"84,984","median_price":"0,39€"}

If you change currency to be equal to 1 (being dollar):

{"success":true,"lowest_price":"$0.49","volume":"84,847","median_price":"$0.48"}

As you can clearly see, currency works perfectly fine with https://steamcommunity.com/market/priceoverview/.

Though as far as I'm aware, https://steamcommunity.com/market/search/render/? doesn't take the currency parameter as an input, i.e. the currency will ultimately be rendered as dollar (or currency=1).

What you could do is to scrape via https://steamcommunity.com/market/search/render/? and looking up the price via https://steamcommunity.com/market/priceoverview/?, though this option will yield pretty inaccurate results (priceoverview only displays a limited amount of details).

On a slight off-topic note: You can convert the price locally (with other APIs or for static currency pairs with a certain factor). Though as you specifically mentioned that you want to do it via the official price (calculating it "manually" ends up with differences, steam-related) that isn't a valid option.

Answer 2

I had the exact same problem and my only solution was including my cookies to the request so steam knows my login and automatically sends prices in my default currency.

"Cookie":  
    "steamMachineAuthXXXXXXXXXXXXXXXXX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX; "
    "Steam_Language=english; "
    "steamLoginSecure=XXXXXXXXXXXXXXXXX||XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX; "

Note: I changed the actual values to "X" for security reasons.
