How Yahoo Auctions Japan Marketplace Scraper Works

1. Give it a keyword — "pokemon", "seiko watch", or the Japanese term itself.
2. Pick a mode: live listings, sold/closed comps, or both in one run.
3. The scraper walks the result pages for that keyword, extracting every listing card until it hits your maxItems cap.
4. Records land in your dataset as clean, flat JSON — ready to export or pipe into whatever you're building.

Input

{
  "keyword": "pokemon",
  "mode": "live",
  "maxItems": 50
}

Field	Type	Default	Description
keyword	string	"pokemon"	Search term — Japanese or romanized English (e.g. "seiko watch", "腕時計")
mode	string	"live"	"live" = active listings only. "sold" = closed/realized-price records only. "both" = run both lanes in one call
maxItems	integer	10	Maximum records to return (applies per lane when mode is "both")
resumeCursor	string	—	Cursor from a previous run's Output, used to continue a crawl that stopped early

Sold-comps example:

{
  "keyword": "seiko watch",
  "mode": "sold",
  "maxItems": 100
}

Resuming a large crawl

Every run emits a resumeCursor in its Output. If a large crawl stops before it finishes — because it hit maxItems, your spend cap (maxTotalChargeUsd), or was aborted — start a new run with the same input plus that resumeCursor to continue from where it left off. The crawl resumes from the queued work the previous run didn't reach.

• You are not re-charged for records the earlier run already delivered.
• Resume within your account's run-retention window — on the free tier, roughly your 10 most recent runs. Once the source run is pruned, its resumeCursor is no longer valid.
• resumeCursor is opaque — supply it unmodified.

FAQ

How do I scrape Yahoo Auctions Japan?

Yahoo Auctions Japan Marketplace Scraper takes a keyword and a mode, then returns matching listings as structured JSON.

How much does Yahoo Auctions Japan Marketplace Scraper cost to run?

It's pay-per-event pricing — you pay per record returned, not a flat monthly fee. Check the Pricing tab on this actor's page for current rates.

What data can I get from Yahoo Auctions Japan?

Active listing prices, bid counts, seller IDs, item condition, and shipping cost — plus, separately, realized sold prices (落札価格) from closed auctions, which is the harder dataset to get and the one most competitors don't offer.

Can I get both live listings and sold prices in one run?

Yes. Set mode to "both" and the actor runs both lanes for the same keyword in a single call.
