# mechanism-emission-split (/docs/query/mechanism-emission-split)

Returns the raw on-chain per-mechanism share values, in mechanism order; an
empty list means no explicit split is set.

**Category:** Subnets

## Parameters [#parameters]

| Parameter | Type    | Description      |
| --------- | ------- | ---------------- |
| `netuid`  | integer | Subnet to query. |

## CLI [#cli]

```bash
btcli query mechanism-emission-split --netuid <integer> --json
```

## Python [#python]

Namespace method (autocomplete, signature help):

```python
import bittensor as bt

sub = bt.Subtensor()
result = sub.subnets.mechanism_emission_split(netuid=1)
```

Or dispatch by name, as an agent would:

```python
result = sub.read("mechanism_emission_split", netuid=1)
```

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