If you'd like to work with **normalized data format** instead (same format for each exchange) see [downloadable CSV files](https://docs.tardis.dev/downloadable-csv-files/overview) or official [client libs](https://docs.tardis.dev/api/quickstart) 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="huobi-dm-options", from_date="2021-03-01", to_date="2021-03-02", filters=[Channel(name="depth", symbols=["BTC-USDT-210326-C-32000"])], api_key="YOUR_API_KEY", ): # messages as provided by HTX Options real-time stream print(message) asyncio.run(main()) ``` See [Python client docs](https://docs.tardis.dev/python-client/quickstart). {% endtab %} {% tab title="Node.js" %} ```javascript // npm install tardis-dev import { replay } from 'tardis-dev'; const messages = replay({ exchange: 'huobi-dm-options', from: '2021-03-01', to: '2021-03-02', filters: [{ channel: 'depth', symbols: ['BTC-USDT-210326-C-32000'] }], apiKey: 'YOUR_API_KEY' }); // messages as provided by HTX Options real-time stream for await (const { localTimestamp, message } of messages) { console.log(localTimestamp, message); } ``` See [Node.js client docs](https://docs.tardis.dev/node-client/quickstart). {% endtab %} {% tab title="cURL & HTTP API" %} ```bash curl --compressed -g 'https://api.tardis.dev/v1/data-feeds/huobi-dm-options?from=2021-03-01&filters=[{"channel":"depth","symbols":["BTC-USDT-210326-C-32000"]}]&offset=0' ``` {% embed url="" %} Example API response for HTX Options historical market data request {% endembed %} See [HTTP API docs](https://docs.tardis.dev/api/http-api-reference). {% endtab %} {% tab title="cURL & tardis-machine" %} ```bash curl -g 'localhost:8000/replay?options={"exchange":"huobi-dm-options","filters":[{"channel":"depth","symbols":["BTC-USDT-210326-C-32000"]}],"from":"2021-03-01","to":"2021-03-02"}' ``` [Tardis-machine](https://docs.tardis.dev/tardis-machine/quickstart) is a locally runnable server that exposes API allowing efficiently requesting historical market data for whole time periods in contrast to [HTTP API](https://docs.tardis.dev/api/http-api-reference) that provides data only in minute by minute slices.
