API Access and data format

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-dev
import asyncio
from tardis_dev import Channel, replay

async def main():
    async for local_timestamp, message in replay(
        exchange="okex-spreads",
        from_date="2024-01-01",
        to_date="2024-01-02",
        filters=[Channel(name="sprd-books5", symbols=[])],
        api_key="YOUR_API_KEY",
    ):
        # messages as provided by OKX real-time stream
        print(message)

asyncio.run(main())

See Python client docs.

  filters: [{ channel: 'sprd-books5', symbols: [] }],
