Aucfan Japan Auction Sold Price Database Scraper

Scrape historical sold prices and price trend data from Aucfan.com — Japan's largest closed-auction price database. Search across Yahoo Auctions, Mercari, Mbok, Rakuma, and other JP marketplaces to retrieve realized closing prices, bid counts, and price trends for any keyword.

What Is Aucfan?

Aucfan (aucfan.com) aggregates historical closed-auction data from Japan's major secondary markets — Yahoo Auctions, Mercari, Rakuma, and more — into a single search interface. Where other tools show live asking prices, aucfan shows realized sold prices: what items actually sold for, how many bids they received, and when they closed. This makes it the authoritative comp-data layer for JP-market resellers, arbitrageurs, and market researchers.

What This Actor Returns

Each record is a closed auction result, with:

Field Description

Input

Parameter Type Required Default Notes
keyword string Yes pokemon Keyword to search (supports kanji, kana, romaji)
maxItems integer Yes 10 Maximum records to return

Example input:

{
  "keyword": "ポケモンカード リザードン",
  "maxItems": 100
}

Usage Notes

  • Results span all active marketplace sources — Yahoo Auctions, Mercari, and others are searched together
  • bid_count is populated for Yahoo Auctions; other marketplaces may return null
  • Price fields are normalized to integer JPY across all sources
  • The actor throttles requests (~1 req / 2-3 sec) to avoid rate limiting; large maxItems values will take proportionally longer
  • Japanese keywords (kanji/kana) work correctly and often return more targeted results than romaji equivalents

Use Cases

  • Reseller comp research: Get realistic sold prices before listing items to buy or sell
  • Price trend analysis: Track how realized prices vary across time and marketplaces for a category
  • Arbitrage identification: Compare sold prices across JP markets to spot mispriced inventory
  • Market research: Build pricing datasets for JP secondary-market categories

Rate Limits

Aucfan rate-limits by IP. The actor uses a conservative 2.5-second inter-request delay with datacenter proxy rotation. For high-volume workloads, increase maxItems per run rather than running many small parallel runs.
