# 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.
