TBC Classic AH Item Response Fields

In the API response I am seeing some fields that I am assuming contain the modifiers to an item but I can not figure out how to relate them back to something useable. Here is an example record.

{
   "id":1174907201,
   "item":{
       "id":24762,
       "rand":-40,
       "seed":1250361393
   },
   "bid":208997,
   "buyout":219997,
   "quantity":1,
   "time_left":"SHORT"
}

Any help identifying how I can translate item.rand and item.seed would be greatly appreciated.

There are some information about it on the API discord.

I would suggest joining and scrolling up the general channel around 2021-06-08.
