Api Endpoint

PreReason

What changed since your last read: one page of PreReason's change events after a cursor. A briefing's state label, a tracked release, and, for the companies you name (?companies=, at most 200), newer figures, a situation turning on or filed news (?kinds= narrows it). Each event says what changed, when it happened, when PreReason knew it and where to fetch it, never a value. With no cursor it answers the last 24 hours; each answer's next_cursor is where the next read starts.
