HTTP API Reference

HTTP based API providing historical market data feeds, supported exchanges details and more
Base API Endpoint: https://api.tardis.dev/v1
get
/data-feeds/:exchange
https://api.tardis.dev/v1/data-feeds/:exchange

Provides historical cryptocurrency market data feed for requested exchange in minute by minute slices in new line delimited JSON format (NDJSON) with addition of local timestamp at the beginning of each line - in ISO 8601 format. JSON message in each line is a data message in exchange-native format.

Empty lines in response are being used as markers for disconnect events that occurred when recording the data.

Responses are being GZIP compressed and each one contains one minute of historical market data starting from requested date which is from date plus minute offset param.

Parallel request to this endpoint are supported and can speed up overall data fetching process substantially,  but don't use more than ~60 parallel requests as it doesn't bring speed benefits.

As this is relatively low level API you may also want to try official client libraries that are built on top of it and provide more convenient way of consuming historical market data like requesting whole date ranges of data at once instead of minute by minute pagination or providing normalized data format. Feel free to contact us in case of any questions.

Response
Request
Path Parameters
exchange
required
string
requested exchange, use /exchanges API for most up to date exchanges list (use exchange.id as value for this param)
Headers
Authorization
optional

Query Parameters
from
required
string
requested UTC start date of historical market data feed (e.g.: 2019-04-05 or 2019-04-05T01:02:00.000Z)
offset
optional
number
minute offset that together with from date specifies exact minute slice of historical data that will be returned (e.g.: from date: 2019-04-05 with offset: 2  will provide historical data between 2019-04-05T00:02:00.000Z and 2010-04-05T00:03:00.000Z)
filters
optional
string
URL encoded JSON string with{channel:string, symbols?: string[]}[] format   with optional historical market data filters,
e.g.: [{"channel":"trade", "symbols":["XBTUSD"]}] 

In order to get the list of allowed channels and symbols for each exchange usehttps://api.tardis.dev/v1/exchanges/:exchange API (documented below).

Sample logic showing how to construct API calls to /data-feeds/:exchange endpoint in JavaScript (can be easily ported to any language - please get in touch in case of any issues).
// supported exchanges ids can be obtained via https://api.tardis.dev/v1/exchanges
const exchange = 'bitmex'

// requested UTC start date of historical market data
const fromDate = '2019-07-01'
​
// optional minute offset that together with from date
// specifies exact minute slice of historical data that will be returned
// in case of this example we'll fetch data for 2019-07-01T00:03:00 UTC
const offset = 3
​
// optional filters array - available channel names and symbols can be
// obtained via https://api.tardis.dev/v1/exchanges/bitmex
const filtersPayload = [
  { channel: 'trade', symbols: ['XBTUSD'] },
  { channel: 'orderBookL2', symbols: ['XBTUSD'] }
]
​
// filters object needs to be in JSON format and URL encoded
// so it can be provided via query string
const filters = encodeURIComponent(JSON.stringify(filtersPayload))
​
const queryParams = `from=${fromDate}&offset=${offset}&filters=${filters}`
​
const url = `https://api.tardis.dev/v1/data-feeds/${exchange}?${queryParams}`
