# gRPC(Mainnet & Testnet Full node, Mainnet Archive)

{% hint style="info" %}
Please download the latest .proto file from the official GitHub and save it locally. <https://github.com/MystenLabs/sui-apis/tree/main/proto>
{% endhint %}

{% hint style="info" %}
Please note that JSON-RPC APIs are only for pruned data. Users requiring archival data should create a SUI Mainnet Archive endpoint and use gRPC.

SUI has announced plans to deprecate the JSON-RPC API. Please refer to the official SUI announcement for the specific timeline. As an official partner, BlockPI will align with SUI’s plan to phase out JSON-RPC support.
