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-swap",
    from_date="2024-01-01",
    to_date="2024-01-02",
    filters=[Channel(name="books-l2-tbt", symbols=["BTC-USD-SWAP"])]
  )

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


asyncio.run(replay())
