The new Steam Community Market (SCM) uses queries to fetch EconItem data. For example, if I access the page for Sealed Dead Hand Terminal in CS2 (appid 730), I can see that the following queryData was used: 
  

[
  {

Does anyone know how I can query this new API endpoint myself? Previously, if I wanted to get the price history of an item, I would use this endpoint which returns only the pricehistory:
https://steamcommunity.com/market/pricehistory?market_hash_name=Sealed%20Dead%20Hand%20Terminal&appid=730

How can I achieve the same result using the new endpoints?
