## Best Practices

Keep the recorded block height and address together when reproducing a historical example. Preserve RPC errors instead of replacing them with empty results.

## Code Examples

```bash
curl -X POST "https://api-etherlink-mainnet.n.dwellir.com/YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  --data-raw '{"jsonrpc":"2.0","id":22,"method":"eth_getBlockByNumber","params":["0x3f84b1",true]}'
```
