Pass the returned `cursor` as `after` on the next call so nothing arriving between calls is missed. Answers 200 with `message: null` and `timed_out: true` when nothing came.

All frames are JSON text.\n\n**Authenticate** with the `Authorization` header on the upgrade, or — from a browser, which cannot set one — send `{\"type\":\"auth\",\"api_key\":\"pgn_live_…\"}` as the first message within ten seconds. Never put the key in the URL.\n\n**The server sends** `{\"type\":\"ready\",\"cursor\"}`, then `{\"type\":\"event\",\"event\":Event}` per event, oldest first. Before about 280 seconds it sends `{\"type\":\"reconnect\",\"cursor\"}` and closes with 4000: reconnect with `after` set to that cursor and nothing is missed. 4401 means no key or a bad one; 4500 means the read failed — reconnect with the last cursor you saw.\n\nLike the stream, it polls the log on our side of the wire every two seconds.",
