# Solana Overview

> Understand Solana Node API networks, method groups, and generated endpoint references.

The **Solana** API Reference documents selected JSON-RPC methods available through Node API endpoints. Use it when your application needs direct Solana node access for cluster health, slots, epochs, account data, SOL supply, blockhashes, and recent performance data.

The generated endpoint reference is built from the OpenRPC specification for **Standard API**. That spec is the source of truth for method names, parameters, response schemas, examples, and generated method pages.

## Chain Description

**Solana** is a public, decentralized blockchain network designed for high-throughput applications, low-latency transactions, and programs that run on a shared global state. Developers use Solana to build applications for payments, DeFi, NFTs, games, and other onchain workflows.

## Solana JSON-RPC API: Standard API

The **Solana JSON-RPC API** provides access to Solana node data and functionality through the JSON-RPC 2.0 interface.

For easier navigation and product differentiation, the available methods are grouped under **Standard API**. Solana Node API does not use the Ethereum-specific **Trace API** or **Debug API** groups.

**Standard API** methods read cluster status, slots, epochs, accounts, supply, blockhashes, and recent performance data. Requests specify a method such as `getHealth`, `getBlockHeight`, or `getAccountInfo`, together with the corresponding parameters in a JSON request body.

Successful responses include a `result` value. Failed responses include an `error` object with error details, so clients should inspect the response body before treating a request as successful.

Together, these methods provide direct access to Solana node data across supported Solana networks, enabling developers to build applications, monitor chain state, and query account or cluster information.

## API Endpoints Supported
