1. Configure — add one or more searchTerms (e.g. nintendo, pokemon card), pick a status (on sale / sold out / all), and optionally add price/brand/condition filters.

3. Get your data — open the Output tab and export to JSON, CSV, Excel or HTML, or pull it via the Apify API.

📥 Input

Give the Actor at least one keyword in searchTerms. Everything else is optional.

Example — new listings for gaming keywords (price-filtered)

{
  "searchTerms": ["nintendo", "pokemon card"],
  "status": "on_sale",
  "sort": "SORT_CREATED_TIME",
  "priceMin": 1000,
  "priceMax": 50000,
  "fetchDetails": false,
  "maxItemsPerTerm": 1000
}

Example — sold-price research (completed sales)

{
  "searchTerms": ["supreme box logo"],
  "status": "sold_out",
  "sort": "SORT_CREATED_TIME",
  "fetchDetails": true,
  "maxItemsPerTerm": 500
}

Example — brand monitoring with seller enrichment

{
  "searchTerms": ["rolex", "omega"],
  "status": "all",
  "fetchDetails": true,
  "maxResults": 2000
}

Field	Type	Description	Default
searchTerms	array	Keywords to search (nintendo, pokemon card, supreme). One search per term. Required.	–
status	enum	on_sale, sold_out or all.	on_sale
sort	enum	SORT_SCORE (best match), SORT_CREATED_TIME, SORT_PRICE, SORT_NUM_LIKES.	SORT_SCORE
priceMin / priceMax	integer	Price range filter in JPY. 0 = no bound.	0
categoryId / brandId / itemConditionId	array	Optional Mercari id filters.	–
fetchDetails	boolean	Also fetch full description + seller stats per item (slower, richer).	false
maxItemsPerTerm	integer	Cap per keyword (paginated). 0 = unlimited.	0
maxResults	integer	Global cap across all keywords. 0 = unlimited.	0
proxyConfiguration	object	Residential proxy (recommended, pre-configured). Mercari is served from Japan.	Residential Apify Proxy

Tip: add many keywords and raise maxItemsPerTerm to build an analysis-ready Mercari dataset in one run. Turn on fetchDetails only when you need descriptions/seller stats, and pair it with a sensible cap since it's slower.

📤 Output

Each listing is saved as one structured record. Here is a trimmed sample:

{
  "id": "m12345678901",
  "url": "https://jp.mercari.com/item/m12345678901",
  "name": "Nintendo Switch 本体 有機ELモデル ホワイト",
  "price": 32000,

  "status": "STATUS_ON_SALE",
  "itemConditionId": "2",
  "categoryId": "1234",
  "brandId": "5678",
  "brandName": "Nintendo",
  "sellerId": "987654321",
  "itemType": "ITEM_TYPE_MERCARI",
  "thumbnail": "https://static.mercdn.net/c!/w=240/thumb/photos/m12345678901_1.jpg",
  "photos": ["https://static.mercdn.net/item/detail/orig/photos/m12345678901_1.jpg"],
  "created": 1717400000,
  "updated": 1717500000,
  "searchTerm": "nintendo",
  "scrapedAt": "2026-07-06T10:00:00.000Z"
}

With fetchDetails: true, each record also includes description, sellerName, sellerNumSellItems, sellerNumRatings and sellerScore.

⚙️ How it works

1. You provide one or more search keywords and optional filters.
2. For each term the Actor queries Mercari's public search API, signing every request with a freshly generated DPoP (ES256) token — no account, no cookies.
3. It paginates with the result-page token until the term is exhausted or your cap is hit.
4. Each item is parsed into a clean record; with fetchDetails it also pulls the full description and seller stats, then streams results to the dataset.

No login, no cookies, no API keys — and no Mercari account is ever used or risked.

❓ Frequently Asked Questions

Do I need a login, cookies or API key? No — the Actor signs its own DPoP tokens for the public search API. No account, no cookies, no developer key — only an Apify account.

Is this a Mercari Japan API alternative? Yes. Mercari has no public developer API, so this works as an unofficial Mercari API alternative — it signs its own DPoP tokens against the public search endpoint, with no API key or login required.

Can I scrape Mercari Japan without an API or login? Yes — this is a no-API-key, login-free way to scrape mercari.jp. It reads only public search data over residential proxies, so no Mercari account is ever used or risked.

Can I scrape Mercari Japan without a Japanese account? Yes. The Actor signs its own DPoP tokens against the public search API over residential proxies, so no Mercari account, cookies or login is ever required.

How many listings can I get per keyword? Thousands — it paginates the full public search result set. Control depth with maxItemsPerTerm and maxResults.

Can I get sold-out (sold price) listings? Yes — set status to sold_out to pull completed sales, or all for both. This returns final prices in JPY for resale research.

How do I research Mercari Japan sold prices for a product? Set status to sold_out and search your product keyword; the scraper returns completed sales with final prices in JPY, exported to CSV or JSON.

Can I filter by price, brand or condition? Yes — use priceMin/priceMax, brandId, categoryId and itemConditionId.

How do I get descriptions and seller ratings? Turn on fetchDetails. It fetches each item's detail page for the full description and seller stats (ratings, score, items sold). It's slower, so combine it with a sensible cap.

Why residential proxies? Mercari is served from Japan; residential proxies give the most reliable access. The default proxy config is set for you.

How do I export Mercari Japan data to CSV or JSON? Every run streams to a dataset you can download as CSV, JSON, Excel or HTML, or pull via the Apify API and webhooks.
