Buy and Sell orders of an item in Steam API/JSON

I'm trying to get buy and sell orders in JSON format like with the price history, but couldn't find any info. Is there a method to do so?

I tried:

https://steamcommunity.com/market/pricehistory/?country=ru&currency=3&appid=730&market_hash_name=Operation%20Riptide%20Case

And:

https://steamcommunity.com/market/listings/730/AWP%20%7C%20Asiimov%20%28Field-Tested%29/render?start=0&count=1&currency=3&language=english&format=json

But they don't display buy and sell orders. Thanks

Try this endpoint: https://steamcommunity.com/market/itemordershistogram

It's the orderbook chart at the bottom of the market pages of popular items, but you can fetch it for any item. Parameters are: country, currency, language, item_nameid, and two_factor.

Just for example parameters, my country, currency, and language are US, 1(USD), and english. two_factor can always be set to 0, and item_nameid is what defines which item you're looking up. There's not an easy way to find it, but you can scrape it from here https://steamcommunity.com/market/listings/<appid>/<market_hash_name> for each item you need. You can find it passed as an argument to the Market_LoadOrderSpread function in the page source. Scraping the ids from this page though is rate limited to ~5 requests per minute.

Best of luck!

Edit: As Illia mentions in more detail below, setting the Referer header seems to significantly increase the rate at which you can send requests to this endpoint without hitting a rate limit.
