What changed (free watch)
what_changedCall this when you have a handle from watch_free and you want what changed on that free watch. Free. Pass handle from watch_free (token is the same value). Reads measured changes for the host on that alerts-free watch only: price, payTo, valid 402, listing or status, and tools-hash or tool changes already stored, plus a receipt link when a receipt was stored. If since is omitted, the window starts when the watch was created (window.basis is since_watch_created). If that time is missing, the window is the last 7 days. Confirm the email before the first read. Not charged. A paid plan token is rejected. changes_since stays the plan-bearer tool.
