The Solana API allows applications to connect to a Solana node that is part of the Solana blockchain. Developers can interact with on-chain data and send different types of transactions to the network by utilizing the endpoints provided by the API.
The Solana API follows a JSON-RPC 2.0 standard. We extended a field named chainId to specify which Solana network we use.
So the entire JSON RPC request body will look as follows：
// Solana get-balance request body
"chainId": 103, // Devnet
The Solana API supports all methods of Solana.
The Solana API offers several enhanced API methods on top of existing official calls.
The Enhanced API is easy and powerful, which makes app-building faster and saves your time.
