When to support explorer interface (non-validator node)?

We want the non-validator node can support the explorer interface , such as: 
```
curl --location 'https://rpc.hyperliquid.xyz/explorer' \
--header 'Content-Type: application/json' \
--data '{
    "hash": "0x4dd80203c98cdb2a15ef041ee256200201250062c5c1c1d328579916f89a6b72",

}'
```
