Remote Procedure Call (RPC) is a protocol that allows a program to execute procedures (functions) on a remote server as if they were local calls. This eliminates the need for developers to handle low-level network communication.

## How Rootstock RPC API Works

Rootstock RPC API uses the JSON-RPC protocol, a lightweight, text-based standard for defining procedures and their parameters. This makes it easy to communicate with the API using JSON-formatted requests and receive structured responses.

## Use Cases

- Building integrations for your product or service.
- Automating workflows with server-side commands.
- Extending your application’s capabilities with remote functions.

## **JSON-RPC Overview**

### What is JSON-RPC?

JSON-RPC is a remote procedure call protocol encoded in JSON. It’s simple, stateless, and transport-agnostic, making it perfect for APIs.

### Supported Features

- **Version:** JSON-RPC 2.0
- **Methods:** Flexible method definitions for various tasks.
