}GetInventoryItem
Returns the inventory item identified by inventory_item_id. Inventory items track an owned asset from receipt through listing and sale, including the current Steam asset_id.
ListAssetIDLinks
Returns the ordered chain of Steam asset IDs for a single inventory item, tracing each rotation across the three trade steps: the original listing, the purchase trade, and the sale trade. The chain is append-only and supports P&L attribution across Steam's asset_id rotation on every trade.
