Mercari Japan Sold Prices — What Items Really Sell For

What it does: Looks up sold (completed) listings on Mercari Japan for your keyword and returns a one-line price summary.

You enter: keywords, e.g. ポケモンカード リザードン psa10 (Japanese works best; brand names like Leica M6 also work)

You get: median sold price, middle 50% range, lowest–highest, average, median days to sell, number of listings found — in yen and US dollars. Optionally every sold listing (title, price, condition, URL).

Price: $0.02 per keyword. +$0.002 per listing if you also want the list. No results = no charge.

Example: enter ポケモンカード リザードン psa10 → median ¥22,750 · range ¥2,030–450,000 · sells in about 3 days · 7,767 listings found

Why sold comps?

Asking prices lie. Sold prices don't. Mercari Japan is the world's largest source of Japanese collectibles — trading cards (Pokémon, One Piece, Yu-Gi-Oh!), anime figures, film cameras, watches, fashion, retro games — but its sold-item data is only browsable in Japanese, one page at a time. This Actor turns it into structured market intelligence:

• Price a collection before you buy or sell — median and quartiles from real completed sales
• Spot arbitrage — compare Japan sold prices against eBay/StockX/your local market
• Track liquidity — medianDaysToSell tells you how fast an item actually moves
• Feed your AI agent or spreadsheet — clean JSON, USD conversion included

Pricing — know your cost before you run

No subscription, no monthly rental — you pay per call:

Event	Price
Price summary (one per keyword)	$0.02
Individual listing record (optional, off by default)	$0.002 each

• A default run costs a flat $0.02 per keyword — the summary is the product. 10 keywords = $0.20.
• Want the raw comps too? Turn on Include individual listings: e.g. 120 listings add $0.24.
• Keywords with zero results are never charged.
• Most scrapers rent by the month; here an occasional price check costs cents.

Input example

{
    "keywords": ["ポケモンカード リザードン psa10", "Leica M6"],
    "itemStatus": "sold_out",
    "maxItemsPerKeyword": 120,
    "convertToUsd": true
}

Japanese keywords give the best coverage. English brand names (Leica, Rolex, Supreme) also work well.

One price_summary record per keyword:

Use with AI agents

This Actor works out of the box with the Apify MCP server, so Claude, ChatGPT, and other MCP-enabled agents can check Japanese market prices autonomously — for example inside an automated sourcing or repricing workflow.
