Checking Solana Wallet Balance Using NOWNodes RPC

For developers building on Solana, retrieving a wallet balance is a common and essential task. In this post, we'll walk through how to check a Solana wallet's balance using the getBalance RPC method through the NOWNodes managed RPC service.

Why Use NOWNodes RPC?

Running and maintaining your own Solana full node can be complex and resource-intensive. NOWNodes provides ready-to-use RPC endpoints with high availability and scalability, allowing developers to focus on application logic rather than node infrastructure.

Key features:

• Full access to Solana RPC endpoints over HTTP and WebSocket

• Zero setup required

• Scalable for production workloads

RPC Method: getBalance

The getBalance method queries the current balance of a Solana account in lamports.

• 1 SOL = 1,000,000,000 lamports

• The method returns an integer value representing lamports

Example Request

Using curl, here's how to make a getBalance request to NOWNodes:

curl --location 'https://sol.nownodes.io' \
--header 'Content-Type: application/json' \
--header 'api-key: YOUR_API_KEY' \
--data '
 {
    "jsonrpc": "2.0", "id": 1,
    "method": "getBalance",
    "params": [
      "83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri"
    ]
  }
'

Replace:

• YOUR_API_KEY with your NOWNodes API key

• The address inside params with the Solana wallet public key to check

Example Response

{
  "jsonrpc": "2.0",
  "result": {
    "context": {
      "slot": 1
    },
    "value": 0
  },
  "id": 1
}

The value field indicates the balance in lamports. To convert to SOL, divide the result by 1_000_000_000.

Use Case

This RPC call is suitable for:

• Wallet applications

• Blockchain explorers

• Backend services that track account balances

• Automated monitoring scripts

Since NOWNodes is a fully managed provider, it's a practical option for production environments where performance and uptime are critical.

Conclusion

To retrieve the balance of a Solana wallet:

1. Obtain a public wallet address

2. Acquire an API key from NOWNodes

3. Use the getBalance RPC call with your credentials

This approach gives you quick, programmatic access to Solana account balances with no infrastructure overhead.
