API Access and data format
Historical data format is the same as provided by real-time Poloniex WebSocket v2 API with addition of local timestamps and also with addition of symbol at the end of each message which allows us providing filtering for the data server-side. 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 perform data normalization client-side.
