Overview

AI-generated overview

Scrapes used-goods listings and prices from OffMall, Hard Off's official Japanese online store, so an assistant can search items by keyword or category.

What you can do
  • Search OffMall used-goods listings by keyword, or scan one of 13 categories when no keyword is given.
  • Collect product records with title, brand, model code, price in JPY, condition rank (S/A/B/C), image and product page links, shop, category and scrape timestamp.
  • Cap the collection with a maximum item count and a maximum number of pages per source.
When to use it
Useful when you want an assistant to look up current second-hand prices and availability for cameras, watches, instruments, luxury brands, phones or game consoles sold through Hard Off stores in Japan, or to compare OffMall prices against other Japanese marketplaces.
Requirements
Runs as a local process (stdio) on the desktop; the README shows a Python 3 launch command and a Smithery install option. The scraper is backed by an Apify actor and a Gumroad listing, so an Apify account or token and a paid plan are implied by the pricing model. Network access to the OffMall site is required.
Before you install
Pricing is pay-per-event (a per-run fee plus a per-item fee), so large scans cost money. It sends requests to a third-party site and depends on external Apify and Gumroad services. Collected data is limited to factual product information, but listings and prices can change at any time.

Why this is useful

  • 800+ stores in one place — OffMall aggregates listings from Hard Off stores across Japan (毎日更新)
  • One-item-only used goods — every listing is a unique physical item with a condition rank (S/A/B/C)
  • Total market scan — search by keyword or scan entire categories (13 categories)
  • Cross-shop arbitrage — compare OffMall prices against Kitamura/Fujiya/Jackroad via the Japan Market family of actors
