Mercari Scraper API
Resale prices on Mercari move by the hour, and there's no public Mercari API to follow them. Our scraper API returns listings, sold prices, seller ratings, and search results from both the US and Japanese marketplaces – the raw material for pricing models and sourcing bots.

What is Mercari scraper API?
Mercari scraper API extracts listings data from one of the busiest resale marketplaces in the US and Japan. Public listing and search pages yield:
- Item titles, categories, and condition grades
- Asking prices and sold-price signals
- Seller names, ratings, and listing counts
- Shipping options and locations
- Keyword and category search results
Resellers run it as their de facto Mercari API for spotting underpriced inventory, while brands track secondary-market pricing on their own products. When a pricing model needs cross-marketplace comps, the eBay Scraper API adds the other half of the resale picture.

Collect Mercari data
The two Mercari marketplaces are effectively different sites – mercari.com for the US and mercari.jp for Japan, each with local formats and defenses. Requests through Residential Proxies in the matching country return each marketplace as local buyers see it. The engine underneath brings JavaScript rendering for infinite-scroll search results, automatic CAPTCHA handling, and a 125M+ pool mixing residential, datacenter, mobile, and ISP IPs. JSON output keeps item fields consistent across both regions.

AI Firms Are Destroying Rare Books for Training Data: Scraping Is the Alternative
Book scraping is the process of collecting public book data, such as titles, ratings, reviews, metadata, and available text, from online sources. It has taken on new relevance as AI companies buy and destructively scan physical books for training data. For material that already exists online, scraping offers a lower-friction, non-destructive way to collect some of the same kind of human-written data.

Frequently asked questions
Is it legal to scrape Mercari?
Nobody consented to your use of their information. People who posted on Mercari agreed to that platform's terms, not to your pipeline. That gap matters under privacy law. Plan around it rather than through it. Our legal explainer on scraping sets out why.
How does the Mercari scraper API bypass blocks and CAPTCHAs?
Mercari applies rate limiting, IP scoring, and JavaScript checks, tuned differently on the US and JP sites. The scraper matches each with locally plausible IPs from the 125M+ pool, rotating fingerprints, and CAPTCHA solving when challenged. Retry logic is built in, so a flaky response never surfaces as a gap in your data.
What output formats does the Mercari scraper API support?
Listings arrive as HTML or as normalized JSON item records, and CSV export is a click away in the dashboard. XHR capture is available when the useful data rides in background requests rather than the page itself. Everything can also stream into your own database via the API.
Can I geo-target Mercari requests to a specific country or city?
Yes, and Mercari makes it essential – the US and Japanese marketplaces are separate worlds. Choose the exit country per request to keep each dataset native. Within the US, finer regional targeting helps when local pickup listings are part of your sourcing radar.
How fast is the Mercari scraper API and can it handle large-scale jobs?
Sourcing runs live or die on freshness, so the API favors low latency – most requests return within seconds. Parallel search sweeps across hundreds of keywords are standard practice, and our note on paging through search results without gaps helps keep long result sets complete.
Can I try the Mercari scraper API for free?
Yes. Activation is free and needs no credit card, and the starter plan includes up to 2K requests – comfortable room to test both marketplaces and confirm the field coverage your pricing model needs.
