Use this when a seller asks what changed recently in US selling rules: Amazon, Walmart, TikTok Shop or Etsy policy updates, or new federal rules ("did Amazon change anything for toys this week?", "any new seller rules?"). It returns this week's changes, each with its source, the page's own date and the day it was checked, and names the pages that could not be checked. Do not use for tariff or duty changes, or for rules outside the US.
