Solana RPC API reference and guides

Read Solana accounts, send transactions, and subscribe to on-chain updates with Solana Tracker HTTP and WebSocket RPC.

Use Solana RPC to query on-chain state, simulate and submit signed transactions, or subscribe to account and network updates. Solana Tracker exposes standard JSON-RPC methods alongside custom queries for token accounts, lookup tables, domains, and priority fees.

Start with a request

Send HTTP requests to https://rpc-data.solanatracker.io/?api_key=YOUR_API_KEY. For subscriptions, use wss://rpc-data.solanatracker.io/?api_key=YOUR_API_KEY. Get an RPC API key from the dashboard.

HTTP quickstart

Read an account balance with curl or Node.js.

WebSocket subscriptions

Subscribe, read notifications, and unsubscribe.

Credits and limits

Check method costs and plan limits.

Find the method you need

• Accounts and SOL balances: start with getAccountInfo, getBalance, or getMultipleAccounts.
• Token holdings: find a wallet’s token accounts with getTokenAccountsByOwnerV2. Read supply with getTokenSupply.
• Transaction history: list signatures with getSignaturesForAddress, then fetch details with getTransaction.
• Transaction submission: simulate, send, and check status. A returned signature does not mean the transaction is confirmed.
• Program accounts: use getProgramAccountsV2 for cursor-based queries. Its response differs from the standard method.
• Lookup tables and domains: follow the lookup table guide or SNS guide.

Choose the right data interface

RPC returns chain data and execution results. For indexed token prices, market data, and wallet analytics, use the Data API guides. For filtered account and transaction streams over gRPC, use Yellowstone gRPC.

Method names and parameters follow the Solana JSON-RPC reference, except where a page describes a Solana Tracker custom method.
