Yahoo Auctions Japan – Sold Price Scraper (落札相場)

Extract sold prices, bid counts, seller ratings, item condition, and end times from Yahoo! Auctions Japan — Japan's largest consumer auction marketplace. Built for international resellers, collectors, and market researchers who need the real 落札価格 (closing price) an item actually sold for, not the asking price. No coding required: enter a keyword, run, and get clean JSON.

Why scrape Yahoo Auctions sold prices?

• Reseller pricing — know the true resale value of an item before you buy, based on what it actually sold for, not what someone is asking.
• Arbitrage — compare Japan sold prices against eBay, Mercari, or your local market to find profitable sourcing opportunities.
• Collector & grading research — track how sold prices for a specific model, edition, or condition grade move over time.
• Cross-marketplace comps — Yahoo Auctions is the natural first leg alongside Mercari and Rakuma / Yahoo! Flea Market; combine all three for a complete Japanese resale price picture.
• AI agents / RAG — feed structured Japanese sold-price data into an LLM workflow. This Actor is discoverable and callable through the Apify MCP server, so a Claude / Cursor / ChatGPT agent can request price research on demand.

How to use it (no coding)

1. Click Try for free / Start.
2. Enter a Search keyword (Japanese or English, e.g. Nintendo Switch or ポケモンカード), and/or a Category ID.
3. Optionally set a Minimum/maximum sold price, choose a Sort by order, and adjust Max items.
4. Click Start and download the results as JSON, CSV, or Excel — or pull them via the API (below).

Input example

{
  "searchKeyword": "Nintendo Switch",
  "sortBy": "endTime",
  "maxItems": 100
}

All fields are optional except that either searchKeyword or categoryId must be provided. Running with just a keyword uses sensible defaults (sort by end time, 100 items, standard proxy).

Output example

Each result is one sold listing:

{
  "auctionId": "x1234567890",
  "title": "Nintendo Switch 本体 グレー 動作確認済み",
  "soldPrice": 18500,
  "currency": "JPY",
  "buyNowPrice": null,
  "isFixedPrice": false,
  "bidCount": 24,
  "watchCount": 31,
  "itemCondition": "目立った傷や汚れなし",
  "endTime": "7/9 01:34終了",
  "categoryId": "2084005926",
  "categoryName": "家庭用ゲーム本体",
  "sellerId": "abc12345",
  "sellerRating": 1523,
  "sellerIsStore": false,
  "imageUrl": "https://auctions.c.yimg.jp/....jpg",
  "url": "https://auctions.yahoo.co.jp/jp/auction/x1234567890",
  "keyword": "Nintendo Switch",
  "scrapedAt": "2026-07-09T01:34:00.000Z"
}

Field notes:

• soldPrice — the actual closing/winning price, not the starting price or asking price.
• isFixedPrice — true means the item sold instantly via 即決/定額 (Buy It Now) rather than competitive bidding, so bidCount may be low or zero even for a legitimate sale.
• sellerIsStore — true indicates a Yahoo Store (business) seller rather than an individual.

How much does it cost?

This Actor uses pay-per-event pricing: a small charge when a run starts, plus a per-result charge for each sold listing returned. You only pay for the data you actually receive, so a 100-item run costs about the price of 100 results. Use maxItems to cap your spend.

Integrations: API, MCP, and AI agents

This Actor is read-only: it only reads publicly available closed-listing pages and performs no login, bidding, or write actions — safe for autonomous agents to call.

API (curl)

curl -X POST "https://api.apify.com/v2/acts/datalab-jp~yahoo-auctions-sold-scraper/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"searchKeyword": "Nintendo Switch", "sortBy": "endTime", "maxItems": 50}'

Synchronous runs time out after 300 seconds. For large scrapes, use the standard run endpoint and fetch the dataset afterwards.

Python (apify-client)

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("datalab-jp/yahoo-auctions-sold-scraper").call(run_input={
    "searchKeyword": "Nintendo Switch",
    "sortBy": "endTime",
    "maxItems": 50,
})
items = client.dataset(run["defaultDatasetId"]).list_items().items
print(items)

JavaScript (apify-client)

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_APIFY_TOKEN' });
const run = await client.actor('datalab-jp/yahoo-auctions-sold-scraper').call({
    searchKeyword: 'Nintendo Switch',
    sortBy: 'endTime',
    maxItems: 50,
});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

MCP / AI agents

This Actor is available through the Apify MCP server. AI agents (Claude, and any MCP-compatible client) can discover it with search-actors, inspect its inputs with fetch-actor-details, and run it with call-actor — no manual setup on your side.

FAQ

Is scraping Yahoo Auctions sold prices legal? This Actor collects only publicly available closed-listing data from Yahoo Auctions' own search results pages. It does not log in, bid, bypass paywalls, or collect private personal data. You are responsible for using the data in accordance with applicable laws and Yahoo Auctions' terms of service.

Can I call this Actor from my own app or API? Yes. Use the Apify API or the apify-client libraries shown above. Every run returns a dataset you can fetch as JSON, CSV, or Excel.

Can AI agents use this Actor? Yes. It is exposed through the Apify MCP server, so agents can find and run it automatically. It is read-only and safe to call.

What's the difference between soldPrice and buyNowPrice? soldPrice is the actual final price the item closed at (via bidding or instant purchase). buyNowPrice is only present if the listing offered an instant-purchase (即決) option, and reflects that price whether or not it was used.

Why does this Actor use a datacenter proxy instead of residential? Yahoo Auctions' closed-search pages have not required residential IPs to load reliably, unlike some other Japanese marketplaces. You can switch to a residential or country-specific proxy in the input if you experience blocking.
