How to put cookie in json request?

Question

JSON

Good day!
I execute the request steamcommunity.com/market/pricehistory/?country=RU...
- works fine if I'm logged into steam.
When trying to execute in an incognito tab, the query returns []. The same request is made when loading the page https://steamcommunity.com/market/listings/730/Gam... (everything works correctly even in the incognito tab).
Perhaps the point is that when visiting the page, it gives out a sessionid, which is somehow used in the request.

How can I put these parameters in the request ( steamcommunity.com/market/pricehistory/?country=RU... ) so that I don't have to get them when visiting the page?

Answer 1

Do you need to get prices in rubles?
If yes, then they are tied to the account, you cannot change them for guests, authorization is required.
