API Access and data format

Historical data format is the same as provided by real-time OKX WebSocket v3 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 can perform data normalization client-side.

Python

# pip install tardis-client
import asyncio
from tardis_client import TardisClient, Channel
tardis_client = TardisClient(api_key="YOUR_API_KEY")

async def replay():
  # replay method returns Async Generator
  messages = tardis_client.replay(
    exchange="okex",
    from_date="2020-01-01",
    to_date="2020-01-02",
    filters=[Channel(name="spot/trade", symbols=[])]
  )

  # messages as provided by OKEx real-time stream
  async for local_timestamp, message in messages:
    print(message)


asyncio.run(replay())

See Python client docs.

Node.js

// npm install tardis-dev
const { replay } = require('tardis-dev');

async function run() {
  try {
    const messages = replay({
      exchange: 'okex',
      from: '2020-01-01',
      to: '2020-01-02',
      filters: [{ channel: 'spot/trade', symbols: [] }],
      apiKey: 'YOUR_API_KEY'
    });

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

run();

See Node.js client docs.

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.
