# delegateInfo\_getDelegates - Bittensor

Returns all delegates available for TAO staking — hotkey, owner coldkey, take percentage, total stake delegated, validator permits per subnet, and more. Delegates are validators who accept stake from other TAO holders in exchange for a take of the rewards.

{% hint style="info" %}
**Bittensor-specific custom RPC method.** This method is implemented by the Subtensor runtime and is not part of the standard Substrate JSON-RPC surface. Call against a GetBlock endpoint configured for the Substrate interface. The [Bittensor Python SDK](https://github.com/opentensor/bittensor) provides typed wrappers; standard Polkadot.js and substrateinterface require the raw RPC interface (see SDK Integration tabs below).

## Parameters

| Parameter | Type   | Required | Description            |
| --------- | ------ | -------- | ---------------------- |
| blockHash | string | No       | Block hash to query at |

## SDK Integration

{% tabs %}
{% tab title="Bittensor SDK (Python)" %}

```python
import bittensor as bt

# Bittensor SDK provides typed wrappers for chain-specific data.
# The subtensor client routes to the appropriate custom RPC under the hood:
subtensor = bt.subtensor(network="finney")  # or pass GetBlock URL

# Example for subnetInfo_getSubnetInfo:
# subnet_info = subtensor.get_subnet_info(netuid=1)
# print(subnet_info)

# Or use the raw RPC interface for any custom method:
result = subtensor.substrate.rpc_request("delegateInfo_getDelegates", [])
print(result)
```
