### Downloadable **CSV** files

Not available.

### API Access and data format

Historical data format is the same as provided by real-time HitBTC WebSocket **v2** 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](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.
