### API Access and data format

Historical data format is the same as provided by real-time KuCoin Spot WebSocket **Market Data API v1** (<https://docs.kucoin.com/#websocket-feed>) 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](https://docs.tardis.dev/downloadable-csv-files/overview) or official [client libs](https://docs.tardis.dev/api/quickstart) that can perform data normalization client-side.
