ebay.at withdrawn from the offered marketplaces: it answers eBay's anti-bot challenge on every proxy pool and from a home IP (0 of 47 attempts on 2026-10-11), the posture eBay UK/Ireland/Canada/Switzerland/Hong Kong have had since August. The card and the domain input now say 10 marketplaces.
Reliability: a pasted startUrls link on a marketplace other than the run's domain (the default is com) failed every try with eBay's Akamai 403 ("Error Page | eBay", reference-id). The client warms each proxy session with a GET of the marketplace homepage to collect the bm_s/bm_so cookies the next request is scored against, and it warmed on the run's domain — but those cookies are scoped Domain=.ebay.<tld>, so a session warmed on ebay.com reached ebay.de with no cookie at all and was scored as cold. Measured 2026-10-11 on residential proxies, ebay.de search page: 0 of 9 after an ebay.com warm-up, 0 of 8 cold, 8 of 10 after an ebay.de warm-up; two cloud runs of the ladder's ebay.de URL case failed 8 of 8 tries each. The warm-up now follows the host of each request, once per session and host, so one run can mix marketplaces in startUrls as the input form promises. Keyword runs on a single domain are unaffected (they always warmed on the right host).
Test: today's ebay.de 403 body is a fixture (it is Akamai's error page, not a consent or captcha page) and an offline test pins the warm-up order: ebay.de/ before the first ebay.de request, ebay.com/ before the first ebay.com one, never twice per host.
