Japan Second-hand Search: Yahoo Auctions & PayPay

Search Japan's biggest second-hand marketplaces in one run and get clean, typed data in English field names:

• Yahoo! Auctions (ヤフオク!) live listings: current price, buy-it-now price, starting price, bids, watchers, end time, condition, category, shipping fee, where it ships from, seller rating
• Yahoo! Auctions sold items: what items actually sold for recently, with the final price and sale date
• PayPay Flea Market (PayPayフリマ): fixed-price listings with price, likes, condition, brand, category, hashtags and seller rating
• Sold-price summary per keyword (free): count, min, quartiles, median, max and average of recent final prices
• Prices in yen and your currency (USD, EUR, GBP, CNY and more, at the European Central Bank rate)

No login, no Japanese phone number, no browser.

Use cases

• Resellers and importers: check what Pokémon cards, sneakers, watches, cameras or game consoles really sell for in Japan before buying or listing.
• Proxy-buying services: feed live listings with prices in your customers' currency.
• Price research: compare live asking prices with recent sold prices for any model.
• Collectors: monitor new listings for a keyword on a schedule.

Example input

{
  "keywords": ["ポケモンカード", "Nintendo Switch 2"],
  "sources": ["yahooAuctions", "yahooAuctionsSold", "paypayFleamarket"],
  "maxItemsPerSource": 100,
  "maxPriceJpy": 60000,
  "currency": "USD"
}

Use Japanese keywords when you can: ニンテンドースイッチ finds far more than "Nintendo Switch". Brand and model names in English (Rolex, iPhone 15, PS5) work well.

The summary covers every sold result for the keyword, accessories and bundles included, so use a precise keyword (model, edition, card name) for a meaningful price range.

type is listing (for sale now), sold or soldSummary. Conditions are translated to new, like new, very good, good, fair and poor.

100 live listings, 100 sold items and 100 PayPay listings for one keyword cost $0.60.

Notes

• Results come in each site's default order. Sorting and condition filters aren't offered because the sites ask crawlers not to use them.
• The price range applies to live listings; sold items cover the most recent sales Yahoo shows for the keyword.
• Seller names are masked by the sites and not collected; only their rating is.
• Titles and categories stay in Japanese, as on the sites.
