# existential-deposit (/docs/query/existential-deposit)

**Category:** Accounts & keys

## Parameters [#parameters]

This read takes no parameters.

## CLI [#cli]

```bash
btcli query existential-deposit --json
```

## Python [#python]

Namespace method (autocomplete, signature help):

```python
import bittensor as bt

sub = bt.Subtensor()
result = sub.balances.existential_deposit()
```

Or dispatch by name, as an agent would:

```python
result = sub.read("existential_deposit")
```

Async is the same surface awaited: `async with bt.Subtensor() as client:`.
