Find discounted products in a category
Discover discounted in-stock products in a category above a minimum discount threshold (discount = current price below the retailer’s list price). Quality-gated: unbranded listings, sub-$5 items, and discounts above 70% (the inflated-list-price spam signature) are excluded. Ranked by discount depth weighted by log(price), so meaningful discounts on real products outrank deep cuts on trinkets. Each deal carries observed_at (when its price was seen).
Query Parameters
Product category. Accepts a human-readable name (e.g. 'electronics', 'beauty') or a taxonomy slug path (e.g. 'electronics/headphones'); matched against the catalog's category tree (exact node, subtree, or path substring). Also accepts a GS1 GPC code (exactly 8 digits, e.g. '10001159') to filter by PRODUCT TYPE instead of by shelf placement — the same product type is shelved under different categories by different retailers, so a category filter answers from a fraction of the data while a GPC code spans them. Coarser codes (class/family/segment) match every brick beneath them. Resolve a phrase to a code with /v1/reference/classify?q=... ; when a code is used, resolved.match_source is 'gpc'.
