Use the Apify Actor "parsebird/mercari-japan-scraper" to scrape Mercari Japan (jp.mercari.com). Call it with the Apify API or the apify-client SDK, e.g. in Python: `from apify_client import ApifyClient; client = ApifyClient("<APIFY_TOKEN>"); run = client.actor("parsebird/mercari-japan-scraper").call(run_input={"startUrls": ["https://jp.mercari.com/en/search?keyword=apple%20watch"], "keyword": "apple watch", "sort": "created_time", "order": "desc", "status": ["on_sale", "sold_out"], "priceMin": 1000, "priceMax": 50000, "limit": 1000}); items = client.dataset(run["defaultDatasetId"]).list_items().items`. Inputs: startUrls (string[], required, search/category/item URLs), keyword (string, optional override), sort (score|created_time|price), order (desc|asc), status (on_sale|sold_out|trading), priceMin/priceMax (integer, JPY), limit (integer, default 50000, max listings per start URL). Output: one JSON record per listing with listing_id, title, price, currency, brand, listing_status, condition_id, seller, shipping, catalog, media, auction, timestamps, and engagement fields.

What does Mercari Japan Scraper do?

Mercari Japan Scraper (also usable as a Mercari API alternative or Mercari JP data extraction tool) turns any jp.mercari.com URL into structured JSON:

• 🔍 Search & category pages — pass a search URL (?keyword=...) or a category URL (?category_id=...) and paginate through results automatically
• 🏷️ Individual item pages — pass a direct jp.mercari.com/item/mXXXXXXXXXX URL to get full listing detail, including description-level fields not present in search results
• 🔀 Mix URL types freely — combine search, category, and item URLs in a single run
• ⚙️ Global filters — override keyword, sort by relevance/newest/price, filter by listing status (on sale, sold out, trading), and set a min/max price in JPY across every search seed
• 🎯 Auction data included — Mercari's auction-style listings return bid count, highest bid, and initial price alongside standard fields
• 🧹 Automatic deduplication — the same listing found via multiple start URLs is only saved and charged once
• 🚫 No login, no cookies, no browser — the Actor talks directly to Mercari's own public search API, so runs are fast and don't need residential proxies for typical volumes

On top of the extraction logic, every run gets Apify platform features: scheduling for recurring price monitoring, full API access and webhooks, ready-made integrations with Zapier, Make, n8n, and Google Sheets, and one-click export to JSON, CSV, Excel, XML, HTML, or RSS.

This is real, unmodified output captured while testing this Actor. Fields are best-effort: some are only populated for auction listings, shop listings, or one of the two source page types, so always null-check optional fields downstream. Use type + ":" + id as an idempotency key when deduplicating or upserting across runs.

Python

from apify_client import ApifyClient

client = ApifyClient("<APIFY_TOKEN>")
run = client.actor("parsebird/mercari-japan-scraper").call(run_input={
    "startUrls": ["https://jp.mercari.com/en/search?keyword=apple%20watch"],
    "sort": "created_time",

    "priceMin": 1000,
    "priceMax": 50000,
    "limit": 1000,
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["title"], item["price"])

JavaScript

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<APIFY_TOKEN>' });
const run = await client.actor('parsebird/mercari-japan-scraper').call({
    startUrls: ['https://jp.mercari.com/en/search?keyword=apple%20watch'],
    sort: 'created_time',
    order: 'desc',
    status: ['on_sale', 'sold_out'],
    priceMin: 1000,
    priceMax: 50000,
    limit: 1000,
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Use cases

• Resale & arbitrage research — compare Mercari Japan prices for electronics, sneakers, collectibles, and fashion against other marketplaces
• Sold-price / comps tracking — filter by sold_out and trading status to build historical sold-price datasets, including auction final prices
• Category and brand monitoring — watch a category or brand for new listings, price drops, or counterfeit activity
• Sourcing for dropshipping — pull structured product and seller data for sourcing pipelines
• Market research and ML pricing models — feed normalized JSON directly into pricing or demand-forecasting models
• Seller and inventory tracking — monitor a specific seller's listings over time via scheduled runs

How it works

1. Each start URL is classified as either an item page (/item/mXXXXXXXXXX) or a search/category page (/search?...).
2. For search/category URLs, the Actor builds a search request from the URL's own query parameters (keyword, category, brand, size, condition, shipping payer, color) plus your global overrides, signs it with a fresh DPoP proof (RFC 9449, ES256), and calls Mercari's own public search API.
3. Results are paginated using Mercari's page tokens until Max listings per URL is reached or results run out.
4. For item URLs, the Actor signs and calls Mercari's item-detail API directly, which returns richer per-listing detail (auction history, full photo set, shipping details).
5. Both response shapes are normalized into one consistent output schema, deduplicated by listing ID, and pushed to the dataset.
6. Each unique listing saved triggers one billing event.

How much does it cost to scrape Mercari Japan?

Mercari Japan Scraper uses Apify's Pay-Per-Event pricing — you're billed per listing saved, not per compute unit, and your Apify plan tier automatically gets a lower rate:

Apify plan	Price per listing	Price per 1,000 listings
Free	$0.00299	$2.99
Bronze	$0.00249	$2.49
Silver	$0.00199	$1.99
Gold	$0.00149	$1.49

One billing event fires each time a new, unique listing is saved to the dataset — duplicate listings found across multiple start URLs are never double-charged. Scraping 1,000 unique listings on a Free Apify account costs about $2.99; the same run on a Gold plan costs about $1.49. Apify also gives every account a free monthly usage allowance that covers this Actor's platform (non-event) costs for light usage — see Apify pricing for current plan details.

FAQ

Do I need a Mercari account to use this Actor? No. It calls Mercari Japan's own public, unauthenticated search and item APIs the same way the jp.mercari.com website does — no login, cookies, or session required.

Can I scrape sold or expired listings? Yes. Set Listing status to sold_out and/or trading to pull historical sold-price data, including final auction prices.

Does the Actor return results in exactly "newest first" order when I sort by created time? Mostly, but not guaranteed — Mercari's own search index does not promise perfectly exact ordering for the "Newest" sort, a known quirk of the underlying API rather than this Actor.

Can I filter by category or brand? Yes — include a category_id, brand_id, size_id, item_condition_id, shipping_payer_id, or color_id query parameter directly in a start URL (the same parameters jp.mercari.com/search uses), and the Actor will apply them automatically.

Can I schedule recurring runs? Yes. Use Apify's Scheduler to run this Actor daily, hourly, or on any custom interval, and pair it with webhooks or integrations to push new listings to Slack, Sheets, or your own API automatically.

Something looks wrong or missing — where do I report it? Open an issue on the Actor's Issues tab in Apify Console. Mercari occasionally changes response fields on their end, and we monitor and patch quickly.

Can I call this from my own code instead of the Console? Yes — see the Python and JavaScript examples above, or the full API reference.

Is it legal to scrape Mercari Japan?

Scraping publicly available data, such as listings visible to any visitor on jp.mercari.com without logging in, is generally considered legal, but you're responsible for how you use the collected data and for complying with Mercari's own Terms of Service and applicable data protection laws (such as Japan's APPI or the EU's GDPR) in your jurisdiction. Avoid collecting personal data beyond what's needed, and don't use this Actor to overload Mercari's servers. Read more in Apify's blog post on the legality of web scraping.
