Complete solution

What ScrapingBee users hit in practice, with the verified fix: ScrapingBee mode=auto plus an explicit tier param is a 400

Do not combine mode=auto with explicit tier parameters like premiumproxy or stealthproxy; the API rejects the combination with a 400. Either let the API auto-select the tier or name one tier explicitly, not both. Also know that passing waitfor turns JavaScript rendering on even if you did not ask for it, which changes the cost and behavior of the request. If you need infinite scroll pagination through a scenario, use the standard premium or datacenter proxies: stealthproxy is incompatible with infinite_scroll. Read a failed request's error body for the parameter name; most 400s are one of these conflicts.

Context: Web (proxlane integrations doc): documents parameter conflicts that return 400s: mode=auto cannot be combined with explicit proxy-tier parameters, and waitfor quietly forces renderjs on. Stealth proxies are incompatible with infinite_scroll.
