How to Check Solana Wallet Balance Using NOWNodes RPC

If you’re building on Solana and need a fast and reliable way to check Solana wallet balance, this guide walks you through the exact method using the getBalance RPC call with NOWNodes.

NOWNodes provides instant access to full Solana nodes through its managed RPC provider, giving you a ready-to-use Solana RPC URL without any setup or maintenance.

Check Solana Wallet Balance with getBalance

To check a Solana wallet balance, you’ll use the getBalance method. It returns the lamport balance of the account tied to the public key you provide.

1 SOL = 1,000,000,000 lamports. The value returned is always in lamports.

Here’s the exact request you can use.

Request

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 actual API key from NOWNodes.io
  • The wallet address inside params with the public key you want to check

Response

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

The value field is the balance in lamports. In this example, the wallet holds 0 lamports.

Why Use NOWNodes?

  • No need to run your own node
