# getBlockHeight

Returns the current block height at the requested commitment (processed, confirmed or finalized), with optional minContextSlot.

## Request

{% tabs %}
{% tab title="cURL" %}

```bash
curl "https://<your-endpoint>.mainnet.rpcpool.com/<your-token>" -s -X POST \
  -H "Content-Type: application/json" \
  -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getBlockHeight",
  "params": [
    {
      "commitment": "finalized"
    }
  ]
}'
```

{% endtab %}

{% tab title="Kit" %}

```typescript
import { createSolanaRpc } from "@solana/kit";

const rpc_url = "https://<your-endpoint>.mainnet.rpcpool.com/<your-token>";
const rpc = createSolanaRpc(rpc_url);

let blockHeight = await rpc.getBlockHeight().send();

console.log("block height:", blockHeight);
```

{% endtab %}

{% tab title="web3.js" %}

```typescript
import { Connection } from "@solana/web3.js";

const connection = new Connection("https://<your-endpoint>.mainnet.rpcpool.com/<your-token>", "confirmed");

let blockHeight = await connection.getBlockHeight();

console.log("block height:", blockHeight);
```

{% endtab %}

{% tab title="Rust" %}

```rust
// Cargo.toml: anyhow = "1", solana-client = "~4.4", solana-commitment-config = "3",
// tokio = { version = "1", features = ["full"] }.
// Requires Rust 1.98.1 or newer (solana-client 4.4).
use anyhow::Result;
use solana_client::nonblocking::rpc_client::RpcClient;
use solana_commitment_config::CommitmentConfig;

#[tokio::main]
async fn main() -> Result<()> {
    let client = RpcClient::new_with_commitment(
        String::from("https://<your-endpoint>.mainnet.rpcpool.com/<your-token>"),
        CommitmentConfig::confirmed(),
    );

    let block_height = client.get_block_height().await?;

    println!("Block height: {:#?}", block_height);

    Ok(())
}
```

{% endtab %}
{% endtabs %}

## Parameters

**`config`** · object · optional

Configuration object containing the following fields:

**`commitment`** · string · default `finalized`

Values: `processed`, `confirmed`, `finalized`

Solana RPC uses the following commitment levels:

| Value       | Description                                                                                                                                                                        |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `processed` | Return data from the highest slot this node has processed on the fork it currently considers best. This is the newest view, but it can still change if the cluster switches forks. |
| `confirmed` | Return data from the highest slot the cluster has finalized. On Alpenglow, `confirmed` and `finalized` are the same level.                                                         |
| `finalized` | Return data from the highest slot that the cluster has finalized. On Alpenglow there are no vote towers or lockouts: a slot is finalized by certificates of aggregated votes.      |

**`minContextSlot`** · number

The minimum slot that the request can be evaluated at.

## Response

```json
{
  "jsonrpc": "2.0",
  "result": 1233,
  "id": 1
}
```

## Result

Block height the node used to answer this request.
