# gemini-ws

Gemini market data v2 (`wss://api.gemini.com/v2/marketdata`), `l2` subscription.

- **Type**: WEBSOCKET · **Rights**: PUBLIC_ATTRIBUTED · **Real-time**: REALTIME (exchange `timestamp` ms)
- **Output**: LAST_PRICE from `trade` events (the initial `l2_updates` snapshot carries recent trades → the newest is emitted). Order-book deltas are not aggregated (no BID/ASK from this connector).
- **Cadence**: trade-driven — quiet pairs update rarely; the stale threshold is therefore 3 minutes.
