Each entry in our item database carries the same metadata Blizzard publishes through the official game-data API. That includes the item's display name, item level, required level, quality tier, primary inventory slot, and class + subclass taxonomy. We surface the metadata so you can scan a category at a glance, sort by what matters to you, and click through to a detailed price-history view.
Pricing is collected on a regular schedule. For Retail we pull a fresh snapshot from the Blizzard auction-house API every hour. For Mists of Pandaria Classic, Burning Crusade Classic, and Season of Discovery we pull from the TradeSkillMaster (TSM) data feed, which aggregates auction-house listings on a weekly cadence for MoP Classic, an hourly cadence for TBC Classic, and an about-twice-daily cadence for Season of Discovery. Every snapshot is timestamped and retained, so the chart on each detail page shows real movement over weeks and months rather than a single instantaneous quote.
The category landing pages exist to make the catalog crawlable and shareable. If you bookmark a category page you can return to the same view on any realm without navigating through filters. If you link a category page to a friend, search engine, or guild forum, the link resolves to a static URL that any visitor can read without an account or saved state. Every page on the site is family-friendly and free to use; we publish category-level pages so search engines can index them the same way.
If a category contains too many items to display on one page, the table is paginated and the pagination controls appear below the list. Use the search box on the main `/database` page to narrow by item name, or pick a subcategory from the sidebar on the left to drill into a specific subclass. Every item in the category links to its full price-history page, where you can see Retail, MoP Classic, TBC Classic, and Season of Discovery pricing side-by-side when applicable. Prices update as soon as a fresh snapshot lands.
