Within Tradeskill, the Item Enchantment subtype gets its own tracked table here. Each row below carries its own price-history page rather than sharing a single blended entry.
Each Item Enchantment row links to a detail page showing the current minimum buyout, the average and median sale price, and total quantity listed. The realm selector compares the same item across servers, and the edition selector appears wherever an item exists in more than one game version.
If you want the full Tradeskill category rather than only Item Enchantment, the breadcrumb above steps back up one level; otherwise the table below covers every tracked item in this subclass.
