Solana’s SPL token ecosystem is vast, and Helius provides multiple APIs to efficiently query token data.
Get balance for a specific token account using RPC:
const response = await fetch ( "https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY" , {
method: 'POST' ,
headers: { 'Content-Type' : 'application/json' },
body: JSON . stringify ({
jsonrpc: '2.0' ,
id: '1' ,
method: 'getTokenAccountBalance' ,
params: [
'3emsAVdmGKERbHjmGfQ6oZ1e35dkf5iYcS6U4CPKFVaa'
]
})
});
const data = await response . json ();
console . log ( data );
