API Access and data format

Historical data format is the same as provided by Aster Spot WebSocket 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-dev
import asyncio
from tardis_dev import Channel, replay

async def main():
    async for local_timestamp, message in replay(
        exchange="aster",
        from_date="2026-09-01",
        to_date="2026-09-02",
        filters=[Channel(name="depth", symbols=["asterusdt"])],
        api_key="YOUR_API_KEY",
    ):
        # messages as provided by Aster Spot real-time stream
        print(message)

asyncio.run(main())

See Python client docs.

Node.js

// npm install tardis-dev
import { replay } from 'tardis-dev';

const messages = replay({
  exchange: 'aster',
  from: '2026-09-01',
  to: '2026-09-02',
  filters: [{ channel: 'depth', symbols: ['asterusdt'] }],
  apiKey: 'YOUR_API_KEY'
});

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

See Node.js client docs.
