API Access and data format

Historical data format is the same as provided by real-time CoinFLEX 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 or official client libs that perform data normalization client-side.

# pip install tardis-dev
import asyncio
from tardis_dev import Channel, replay

async def main():
    async for local_timestamp, message in replay(
        exchange="coinflex",
        from_date="2020-08-01",
        to_date="2020-08-02",
        filters=[Channel(name="futures/depth", symbols=["BTC-USD-SWAP-LIN"])],
        api_key="YOUR_API_KEY",
    ):
        # messages as provided by CoinFLEX 2.0 real-time stream
        print(message)

asyncio.run(main())

See Python client docs.

// npm install tardis-dev
import { replay } from 'tardis-dev';

const messages = replay({
  exchange: 'coinflex',
  from: '2020-08-01',
  to: '2020-08-02',
  filters: [{ channel: 'futures/depth', symbols: ['BTC-USD-SWAP-LIN'] }],
  apiKey: 'YOUR_API_KEY'
});

// messages as provided by CoinFLEX 2.0 real-time stream
for await (const { localTimestamp, message } of messages) {
  console.log(localTimestamp, message);
}

See Node.js client docs.

curl --compressed -g 'https://api.tardis.dev/v1/data-feeds/coinflex?from=2020-08-01&filters=[{"channel":"futures/depth","symbols":["BTC-USD-SWAP-LIN"]}]&offset=0'

See HTTP API docs.

curl -g 'localhost:8000/replay?options={"exchange":"coinflex","filters":[{"channel":"futures/depth","symbols":["BTC-USD-SWAP-LIN"]}],"from":"2020-08-01","to":"2020-08-02"}'

Tardis-machine is a locally runnable server that exposes API allowing efficiently requesting historical market data for whole time periods in contrast to HTTP API that provides data only in minute by minute slices.

See tardis-machine docs.
