Getting Data Quickstart

Make your first Solana data query in minutes. Copy-paste examples for getTransactionsForAddress, getTransfersByAddress, the DAS API, and the Wallet API.

Quick setup

Every example below needs only your Helius API key from dashboard.helius.dev. Replace YOUR_API_KEY, then pick the path that matches what you’re fetching:

You want	Use this	Returns
An address’s full transaction history	getTransactionsForAddress	Decoded transactions for one address
An address’s full transfers history	getTransfersByAddress	Token and native SOL transfers for one address
Tokens, NFTs, and assets owned by a wallet	DAS API — getAssetsByOwner	Assets with metadata, ownership, and balances
Wallet balances with USD values over REST	Wallet API — /balances	Token and NFT balances with USD pricing

Option 1: Backfill transaction history (getTransactionsForAddress)

getTransactionsForAddress returns the full, decoded transaction history for an address in a single method — the fastest way to backfill data for indexing. Pass the address first, then an options object with optional filters.

TypeScript

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: 'getTransactionsForAddress',
    params: [
      '86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY',
      {
        transactionDetails: 'full',
        sortOrder: 'desc',
        limit: 100,
      },
    ],
  }),
});

const { result } = await response.json();
console.log(`Fetched ${result.data.length} transactions`);

Option 2: Get transfer history (getTransfersByAddress)

getTransfersByAddress returns parsed token and native SOL transfer history for an address — at the transfer level rather than the transaction level, ready for reconciliation. Pass the address; add an options object for filters.

TypeScript

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: 'getTransfersByAddress',
    params: ['86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY'],
  }),
});

const { result } = await response.json();
console.log(`Fetched ${result.data.length} transfers`);

Option 3: Get a wallet’s assets (DAS API)

The DAS API returns the NFTs, fungible tokens, and compressed assets a wallet owns in a single call — the most common starting point for wallets, portfolio views, and analytics.

TypeScript

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: 'getAssetsByOwner',
    params: {
      ownerAddress: '86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY',
      page: 1,
      limit: 1000,
      options: {
        showFungible: true,
        showNativeBalance: true,
      },
    },
  }),
});

const { result } = await response.json();
console.log(`Found ${result.total} assets`);

Option 4: Get wallet balances over REST (Wallet API)

The Wallet API is a high-level REST API. The balances endpoint returns a wallet’s token and NFT holdings with USD values — no JSON-RPC envelope required.

TypeScript

const address = '86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY';
const response = await fetch(
  `https://api.helius.xyz/v1/wallet/${address}/balances?api-key=YOUR_API_KEY`,
);

const data = await response.json();
console.log(`Current page value: $${data.totalUsdValue}`);
