# RPC Endpoints

{% hint style="info" %}
Since FNCY is a public chain, anyone can download FNCY blockchain's pre-built node binary and manage it directly. However, this feature will be provided through a document update in the future. If you need to directly operate through the node binary, please contact [github-g@nm-metalabs.com](mailto:github-g@nm-metaworld.com) and we will provide a guide upon internal review.
{% endhint %}

If you do not install nodes directly, you can use FNCY's public network endpoint, the RPC server, to interact with on-chain data and run transactions on the network. The provided API follows the JSON-RPC standard, and JSON-RPC is a Remote Procedure Call (RPC) protocol commonly used in blockchain.
