WebSocket URL Notice

This endpoint currently uses the following WebSocket URL: 
wss://analytics-ws.amberdata.com/prices
This temporary URL applies only to the Prices WebSocket endpoint while we complete internal infrastructure updates for the new Prices WebSocket service. All other WebSocket endpoints will continue to use the existing standard WebSocket URL. Once this work is complete, the Prices WebSocket endpoint will be migrated to align with our standard WebSocket URL structure. We will provide notice before making any changes that require client-side updates.
