API Access and data format
Historical data format is the same as provided by real-time Gemini WebSocket Market Data Version 2 API with addition of local timestamps. If you'd like to work with normalized data format instead (same format for each exchange) see downloadable CSV files or official client libs that can perform data normalization client-side.
