CryptoDataAPI: Delayed event preview (no key). A free, keyless preview of the stream: the events from a 3-minute window that ended 30 minutes ago (`window_start`/`window_end`, event time, ms), oldest first, at most 900. `server_now` lets a client replay them at their original pace (`ts + delay_ms`). `events_per_min` is the window's rate. Cached for 60s. For real-time events use `GET /stream` (Pro).
