# Tardis Machine Server [![Version](https://img.shields.io/npm/v/tardis-machine.svg)](https://www.npmjs.org/package/tardis-machine) [Tardis-machine](https://docs.tardis.dev/api/tardis-machine) is a locally runnable server with built-in data caching that uses [Tardis.dev HTTP API](https://docs.tardis.dev/api/http) under the hood. It provides both **tick-level historical** and **consolidated real-time cryptocurrency market data** via HTTP and WebSocket APIs. Available via [npm](https://docs.tardis.dev/api/tardis-machine#npm) and [Docker](https://docs.tardis.dev/api/tardis-machine#docker).

![overview]()
## Features - efficient data replay API endpoints returning historical market data for whole time periods \(in contrast to [Tardis.dev HTTP API](https://docs.tardis.dev/api/http) where single call returns data for single minute time period\) - [exchange-native market data APIs](https://docs.tardis.dev/api/tardis-machine#exchange-native-market-data-apis) - tick-by-tick historical market data replay in [exchange-native format](https://docs.tardis.dev/faq/data#what-is-a-difference-between-exchange-native-and-normalized-data-format) - [HTTP](https://docs.tardis.dev/api/tardis-machine#http-get-replay-options-options) and [WebSocket](https://docs.tardis.dev/api/tardis-machine#websocket-ws-replay-exchange-exchange-and-from-fromdate-and-to-todate) endpoints - [WebSocket API](https://docs.tardis.dev/api/tardis-machine#websocket-ws-replay-exchange-exchange-and-from-fromdate-and-to-todate) providing historical market data replay from any given past point in time with the same data format and 'subscribe' logic as real-time exchanges' APIs - in many cases **existing exchanges' WebSocket clients can be used to connect to this endpoint** - [normalized market data APIs](https://docs.tardis.dev/api/tardis-machine#normalized-market-data-apis)
- consistent format for accessing market data across multiple exchanges - [HTTP](https://docs.tardis.dev/api/tardis-machine#http-get-replay-normalized-options-options) and [WebSocket](https://docs.tardis.dev/api/tardis-machine#websocket-ws-replay-normalized-options-options) endpoints - synchronized [historical market data replay across multiple exchanges](https://docs.tardis.dev/api/tardis-machine#http-get-replay-normalized-options-options) - [consolidated real-time data streaming](https://docs.tardis.dev/api/tardis-machine#websocket-ws-stream-normalized-options-options) connecting directly to exchanges' WebSocket APIs - customizable [order book snapshots](https://docs.tardis.dev/api/tardis-machine#book_snapshot_-number_of_levels-_-snapshot_interval-time_unit) and [trade bars](https://docs.tardis.dev/api/tardis-machine#trade_bar_-aggregation_interval-suffix) data types - seamless [switching between real-time data streaming and historical data replay](https://docs.tardis.dev/api/tardis-machine#normalized-market-data-apis)
- transparent historical local data caching \(cached data is stored on disk in compressed GZIP format and decompressed on demand when reading the data\)
- support for top cryptocurrency exchanges: BitMEX, Deribit, Binance, Binance Futures, FTX, OKEx, Huobi Global, Huobi DM, bitFlyer, Bitstamp, Coinbase Pro, Crypto Facilities, Gemini, Kraken, Bitfinex, Bybit, OKCoin, CoinFLEX and more
