參數說明

compare_prices

參數 類型 預設值 說明
query str (必填) 搜尋關鍵字
top_n int 20 回傳筆數
min_price int 0 最低價格過濾 (0=不過濾)
max_price int 0 最高價格過濾 (0=不過濾)
require_words list[list[str]] None 關鍵字分組過濾。組與組是 AND 關係,組內是 OR 關係。例:[["SONY", "索尼"], ["電視", "TV"]] = (SONY OR 索尼) AND (電視 OR TV)
include_auction bool False 是否包含 Yahoo 拍賣競標商品 (預設僅含立即購買)
platform str None 指定單一平台搜尋。None = 搜尋所有平台。可選:pchome, momo, coupang, etmall, rakuten, yahoo_shopping, yahoo_auction

回傳值str (TOON 格式) - 壓縮序列化的產品列表,以降低 LLM token 消耗

使用範例

# 搜尋所有平台最低價(預設)
compare_prices(query="SONY 50吋電視")

# 只搜尋 momo 平台
compare_prices(query="SONY 50吋電視", platform="momo")

# 只搜尋 PChome 平台的 Apple 產品
compare_prices(query="Apple AirPods Pro", platform="pchome")

# 搜尋特定品牌(符合其中一個即可)
compare_prices(
    query="無線耳機",
    require_words=[["Apple", "Beats", "Sony"]]  # 品牌過濾
)

# 複雜過濾:品牌 AND 功能
compare_prices(
    query="藍牙喇叭",
    require_words=[["JBL", "BOSE"], ["防水", "IP67"]],  # (JBL OR BOSE) AND (防水 OR IP67)
    min_price=500,
    max_price=5000
)

# 搜尋包含 Yahoo 拍賣競標商品
compare_prices(query="iPhone 15", include_auction=True)

提示:Coupang 等平台的搜尋結果有時會包含不相關的低價商品,使用 require_words 可有效過濾。
