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
get
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 collecting the data.
Responses are gzip compressed (
content-encoding: gzip) 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 using more than ~60 parallel requests doesn't bring speed benefits.
In order to achieve best performance HTTP 1.1 protocol is recommended, in our testing HTTP 2 was noticeable slower.
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.

Path Parameters
exchange
required
string
one of https://api.tardis.dev/v1/exchanges (field
id)Headers
Authorization
optional
string
For authenticated requests provide Authorization header with value: '
Bearer YOUR_API_KEY'.
Without API key historical data feeds for the first day of each month are available.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).Response
200: OK
Each line contains local timestamp (ISO 8601) and JSON message in exchange native data format

Not sure what is the channel field?​
See downloadable CSV files documentation and related datasets API if you'd like to access historical tick-by-tick trades, order book snapshots, incremental order book L2 updates, options chains, quotes and derivative tickers datasets in daily intervals split by exchange, data type and symbol. It may be faster and more native to your toolkit to access the historical data this way.
