# zks\_getL1GasPrice - zkSync

Example code for the zks\_getL1GasPrice JSON-RPC method. Сomplete guide on how to use zks\_getL1GasPrice JSON-RPC in GetBlock.io Web3 documentation.

Returns the current L1 gas price used in fee calculations. The L1 gas price contributes to L2 transaction costs because posting pubdata to L1 is part of every transaction's fee.

## Parameters

* None

{% tab title="zksync-ethers (JavaScript)" %}

```javascript
import { Provider } from 'zksync-ethers';

const provider = new Provider('https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/');

// zksync-ethers exposes both standard Ethereum methods and zks_* methods
// through typed accessors. For raw access:
const result = await provider.send('zks_getL1GasPrice', []);
console.log(result);
```

{% endtab %}

{% tab title="zksync2-python (Python)" %}

```python
from zksync2.module.module_builder import ZkSyncBuilder

zk_web3 = ZkSyncBuilder.build('https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/')

# zksync2-python exposes the JSON-RPC layer directly.
result = zk_web3.zksync._zks_endpoints if 'zks_getL1GasPrice'.startswith('zks_') else None
# Or call any method generically:
result = zk_web3.provider.make_request('zks_getL1GasPrice', [])
print(result)
