If you'd like to work with **normalized data format** instead (same format for each exchange) see [downloadable CSV files](/downloadable-csv-files/overview.md) or official [client libs](/api/quickstart.md) that can perform data normalization client-side. {% tabs %} {% tab title="Python" %} ```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", from_date="2024-01-01", to_date="2024-01-02", filters=[Channel(name="books", symbols=["BTC-USDT"])], api_key="YOUR_API_KEY", ): # messages as provided by OKX real-time stream print(message) asyncio.run(main()) ``` See [Python client docs](/python-client/quickstart.md). {% endtab %} {% tab title="Node.js" %} ```javascript // npm install tardis-dev import { replay } from 'tardis-dev'; const messages = replay({ exchange: 'okex', from: '2024-01-01', to: '2024-01-02', filters: [{ channel: 'books', symbols: ['BTC-USDT'] }], apiKey: 'YOUR_API_KEY' }); // messages as provided by OKX real-time stream for await (const { localTimestamp, message } of messages) { console.log(localTimestamp, message); } ``` See [Node.js client docs](/node-client/quickstart.md). {% endtab %} {% tab title="cURL & HTTP API" %} ```bash curl --compressed -g 'https://api.tardis.dev/v1/data-feeds/okex?from=2024-01-01&filters=[{"channel":"books","symbols":["BTC-USDT"]}]&offset=0' ``` {% embed url="" %} Example API response for OKX Spot historical market data request {% endembed %} See [HTTP API docs](/api/http-api-reference.md). {% endtab %} {% tab title="cURL & tardis-machine" %} ```bash curl -g 'localhost:8000/replay?options={"exchange":"okex","filters":[{"channel":"books","symbols":["BTC-USDT"]}],"from":"2024-01-01","to":"2024-01-02"}' ``` [Tardis-machine](/tardis-machine/quickstart.md) is a locally runnable server that exposes API allowing efficiently requesting historical market data for whole time periods in contrast to [HTTP API](/api/http-api-reference.md) that provides data only in minute by minute slices.
