Mercari Sold Price Scraper - Yahoo Auctions & PayPay Comps

What does Japan Resale Price Checker do?

What did it actually sell for in Japan? This Actor answers that in a single call. For any keyword it pulls recent verified sold listings — not asking prices — from Japan's three largest secondhand marketplaces and returns one unified price analysis with min, median, max and every underlying comp.

• Mercari (メルカリ) — Japan's #1 C2C app, sold-out filter
• Yahoo Auctions (ヤフオク) — closed auctions with bid counts
• PayPay Flea Market (PayPayフリマ) — completed sales

Sold comps are what pricing decisions actually need. Active listings tell you what sellers hope to get; this Actor tells you what buyers paid. Run it in the Console, hit it via API, schedule daily price tracking, or let an AI agent call it through MCP.

Why use Japan Resale Price Checker?

• Proxy buying and export arbitrage — source in Japan, sell on eBay or StockX. Know your true cost basis before you bid.
• Reselling and sourcing — trading cards, sneakers, watches, cameras, anime figures, vintage fashion, luxury bags.
• Price your own listings — see the real clearing price instead of guessing from what is currently listed.
• Pricing tools and AI agents — one call returns a complete, structured comp report.
• Trend tracking — schedule a keyword daily and chart how its median moves.

Why cross-market matters

The same search clears at very different prices per platform. A live run on a Pokémon card query returned these medians across 90 sold listings:

Marketplace	Median sold price
Yahoo Auctions	¥82,000
Mercari	¥80,750
PayPay Flea Market	¥29,050

That spread is where sourcing margin lives — and you only see it by querying all three at once. Part of any gap reflects a different mix of items per platform, so narrow your keyword (card number, model code, grade) before treating a spread as pure arbitrage.

Every listing returned is verified sold. Items still on sale are excluded, and auctions that closed without a single bid are dropped, so asking prices never leak into your statistics.

How to use Japan Resale Price Checker

1. Click Try for free.
2. Enter a Search keyword. Japanese matches the most inventory (ポケモンカード リザードンex SAR), but brands and model numbers in Latin script work too (Nintendo Switch 2, Rolex Submariner).
3. Optionally add an Exclude keyword (ジャンク 傷あり) to strip damaged goods.
4. Optionally set a USD/JPY rate to get the summary in dollars as well.
5. Click Start, then read the summary in the Output tab.

How much does it cost to check Japanese resale prices?

Pay per event, charged once per keyword analysed — regardless of how many comps come back:

Event	Price
Price check (all marketplaces)	$0.05

Checking 100 items costs $5. A daily job tracking 50 keywords runs about $75/month. Apify's free tier includes $5 of monthly usage, which covers roughly 100 checks before you pay anything. A single check can return up to 300 sold comps.

Tips

• Narrow keywords give tighter, more usable medians. リザードンex SAR 201/165 beats ポケモンカード.
• Use excludeKeyword (ジャンク 傷あり コピー) to strip damaged goods and reproductions out of your comps.
• Median beats mean here — a single graded or sealed outlier will drag the average far from reality.
• Raise maxPerMarketplace for a stable median on high-volume items; lower it for fast, cheap spot checks.
• Comparing across time? Keep the keyword byte-identical so you are measuring the market, not your query.

FAQ

Is scraping these marketplaces legal? The Actor uses public search endpoints only — no login, no paywall bypass, modest request volume per run. Scraping publicly available data is generally lawful in many jurisdictions, but you are responsible for each source site's terms and your local regulations. Prices are historical sold data, not an appraisal or investment advice.

Are these really sold prices? Yes. Mercari is filtered to sold-out status, Yahoo Auctions to closed auctions, and PayPay Flea Market to its sold filter — and each listing's status is re-checked in the response before it is counted. Auctions that ended with zero bids never sold, so they are discarded.

Why does one marketplace return fewer comps? Thin categories simply have fewer recent sales there. The statistics stay valid; count per marketplace tells you how much weight each median deserves.

Can you add another marketplace or currency? Use the Issues tab — Rakuma and Suruga-ya are candidates, and custom Japanese data sources can be built on request.
