All data is available in >=1 minute resolution. The endpoints [/futures](https://api.velo.xyz/api/v1/futures), [/options](https://api.velo.xyz/api/v1/options), and [/spot](https://api.velo.xyz/api/v1/spot) can be used without authentication to view available products and their histories. See the Columns page for available data types.

```python
from velodata import lib as velo

client = velo.client('api_key')

ten_minutes_ms = 1000 * 60 * 10

params = {
      'type': 'futures',
      'columns': ['close_price', 'funding_rate'],
      'exchanges': ['binance-futures', 'bybit'],
      'products': ['BTCUSDT'],
      'begin': client.timestamp() - ten_minutes_ms,
      'end': client.timestamp(),
      'resolution': '1m'
    }
    
print(client.get_rows(params))
```

The API can be accessed via HTTP/Curl, our Python library, or our NodeJS library. Access also includes the ability to download CSV data from applicable charts via the webapp.
