# zks\_getBlockDetails - zkSync

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

Returns zkSync-specific details for an L2 block: status (verified/proven/committed/executed), corresponding L1 batch, operator address, protocol version, and gas prices.

## Parameters

| Parameter   | Type    | Required | Description                  |
| ----------- | ------- | -------- | ---------------------------- |
| blockNumber | integer | Yes      | The L2 block number to query |
