Mercari residential proxies
Mercari leans on commercial bot-management with reCAPTCHA-style interactive challenges and strict per-account and per-IP rate limits rather than a single always-on fingerprinting vendor. Its two marketplaces behave like different sites: Mercari US and Mercari Japan (メルカリ) have separate catalogs and currencies, and the JP side is effectively geo-fenced to Japanese IPs. Public listing data - price, condition, sold status, seller ratings - is readable, but only when your exits sit in the right country and stay under the velocity caps.
Mercari's gating is driven mainly by rate limits and occasional CAPTCHA rather than continuous behavioral scoring, so clean residential IPs with correct geo and gentle pacing clear it reliably - making Premium the right cost/reliability fit. The one place Elite earns its keep is sustaining consistent Japan-in-country exits at higher volume.
Why Mercari is hard
- The Japan marketplace is geo-fenced, so a non-JP exit sees a blocked or emptied catalog
- Aggressive per-IP and per-account velocity limits throttle sequential category crawls quickly
- Interactive CAPTCHA challenges surface as soon as request cadence looks non-human
- Most listings are single-quantity, so an item vanishes the moment it sells - capturing real sale prices means frequent snapshots, not one retrospective crawl
How to approach Mercari with Aethyn
Targeting & session tips
- -country-jp is mandatory for reliable Mercari Japan access; -country-us for the US catalog
- Elite Japan exits help when you need sustained JP volume with fewer regional gaps
- Keep concurrency per IP low - breadth should come from more IPs, not faster hits per IP
