Instructions
Search Rakuten's Item Price Navi — cross-seller product catalogue that groups identical products across multiple shops. Returns each product with its min/max/average price across all sellers and the total number of shops carrying it. Use this (instead of ichiba_item_search) when you want to compare prices for a specific product or answer 'is this a fair price?'. Filter by maker_code to restrict to a brand.
[JA] 楽天市場の商品価格ナビを検索します。同一商品を複数店舗にまたがって集約し、最安値/最高値/平均価格と取扱店舗数を返します。特定商品の価格比較や「妥当な価格か?」を判断する用途では、ichiba_item_search ではなくこちらを使用してください。maker_code でブランド絞り込みも可能。
