Lukka's WebSocket streaming surface for institutional digital-asset market data: executed trades, Level-1 order-book quotes, Lukka Prime pricing, Lukka Index valuations, Standard and Median Reference Rates, real-time MVWAP, derivative Greeks, and prediction-market trades and quotes. Every stream is authenticated with a Lukka-issued JWT bearer token supplied as the `access_token` query parameter on the connection URL. Tokens expire; the server emits a token-expiry notice and the client reauthorizes in-band with an `authenticate` action message. Subscriptions are managed in-band with `subscribe` / `unsubscribe` action messages carrying pair codes, source ids and asset codes. Several streams support a ping/pong heartbeat.
