Mercari proxies for production scraping.
Recommended setup: residential proxies, rotating sessions, based on what we see working in production against Mercari. Copy the recipe and ship.
Mercari's anti-bot reality.
A Mercari proxy routes your scraper through a residential IP, so Mercari sees an ordinary visitor instead of a server. SimplyNode's recommended setup for Mercari is residential proxies with rotating sessions, country-matched to your data. It is the same pay-as-you-go pricing as everywhere — no Mercari surcharge. Sites like Mercari flag datacenter IP ranges, repeated fingerprints, and aggressive request rates. Residential IPs from real homes clear the IP-reputation checks; the rest is pacing and good session hygiene.
Captcha challenges
"Are you a robot?" pages trigger on suspicious IPs plus network-layer fingerprinting. Residential IPs avoid most of it.
Geo-priced content
Prices and content differ by country; the wrong IP returns the wrong market's data. Country targeting matters.
Aggressive rate limits
Too many requests from one IP is ban-bait; even residential IPs need rotation and cooldowns at scale.
Session-required pages
Carts, checkout, and some pages need session continuity. Rotating IPs break the flow; sticky sessions fix it.
What teams scrape from Mercari.
Teams use Mercari proxies to scrape product and price data at scale — for price and availability monitoring, catalog research, and competitive tracking. Pair residential proxies with country-matched geo and rotating sessions, and keep request rates human.
Product & listing data
Pull titles, specs, images, and variants across a catalog. Rotating residential IPs, country-matched, no session needed.
Pricing & availability
Track prices and stock over time and by market; the same product differs by country, so pin the geo.
Ratings & reviews
Paginate reviews for sentiment and review-fraud signals; use sticky sessions since pagination tracks state.
Search & rankings
Monitor search rankings and sponsored placements; per-city for geo-priced results.

Mistakes that get you blocked on Mercari.
We see these constantly in customer pipelines. Each fix is a one-line change.
Using datacenter proxies
Datacenter IPs get flagged instantly. Use residential — we don't sell datacenter for this reason.
Wrong country = wrong data
Pin the country (e.g. country-us) so you get the right localized prices/results, not a default.
Rotating mid-pagination
Use a sticky session for a single multi-page walk; switch sessions only between separate items.
Default / blank User-Agent
python-requests and curl UAs are blocked on sight. Send a realistic browser User-Agent.
