# subnet-registration-cost (/docs/query/subnet-registration-cost)

Denominated in TAO. The cost is dynamic: it rises when subnets register
and decays back down over time.

**Category:** Subnets

## Parameters [#parameters]

This read takes no parameters.

## CLI [#cli]

```bash
btcli query subnet-registration-cost --json
```

## Python [#python]

Typed namespace method (autocomplete, signature help):

```python
import bittensor as sub

async with sub.Client("finney") as client:
    result = await client.subnets.subnet_registration_cost()
```

Or dispatch by name, as an agent would:

```python
result = await client.read("subnet_registration_cost")
```
