### Ethereum JSON-RPC API

Use the Web3.js `eth` package to fetch data from the ZKsync [Ethereum JSON-RPC API](https://docs.zksync.io/build/api-reference/ethereum-rpc).
ZKsync Era implements the [Ethereum JSON-RPC API](https://docs.zksync.io/build/api-reference/ethereum-rpc),
so you can use the Web3.js `eth` package to fetch data from the Layer 1 _and_ Layer 2 networks.

#### Fetch the Latest Block Number

```javascript
const blockNumber = await web3.eth.getBlockNumber();
console.log(`Current block number: ${blockNumber}`);
const l1BlockNumber = await web3.eth.getBlockNumber();
console.log(`Current L1 block number: ${l1BlockNumber}`);
const l2BlockNumber = await web3.ZKsync.L2.eth.getBlockNumber();
console.log(`Current L2 block number: ${l2BlockNumber}`);
```
