Every app, bot, and dashboard in the Solana ecosystem talks to the blockchain through APIs. When you check your wallet balance in Phantom, it calls an API. When a trading bot executes a swap on Jupiter, it calls an API. When a portfolio tracker shows your DeFi positions across 15 protocols, it calls a lot of APIs.
But "Solana API" is a loose term that covers very different things. The API you need for building a simple wallet viewer is completely different from what you need for a sub-second trading bot or an on-chain analytics dashboard. Picking the wrong one means you either overpay for features you do not need, or you build on a foundation that breaks the moment you need something it cannot do.
This guide breaks down the types of Solana APIs, what each one is built for, and how to pick the right one for what you are building.
The Core Layer: Solana JSON-RPC
Solana RPC nodes expose a JSON-RPC API; a validator does not have to offer a public RPC service. This is the base layer that everything else is built on top of. When you hear "Solana RPC" or "RPC endpoint," this is what people mean.
The JSON-RPC API lets you:
- Read account data — token balances, program state, stake accounts
- Submit transactions — send SOL, swap tokens, interact with any program
- Subscribe to changes — WebSocket subscriptions for account updates, slot notifications
- Query transaction history — look up individual transactions by signature
A standard RPC call to get a wallet's SOL balance looks like this:
curl "$SOLANA_RPC_URL" -X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"getBalance","params":["YOUR_WALLET_ADDRESS"]}'
Set SOLANA_RPC_URL to your configured provider endpoint and replace the wallet placeholder with a valid public key. getBalance returns lamports (1 SOL = 1,000,000,000 lamports). Check HTTP status and JSON-RPC error before reading the result.
When Raw RPC Is Enough
If you are building something that only needs to read a few accounts or submit transactions occasionally, the raw RPC is all you need. A staking dashboard that checks validator performance, a payment integration that verifies SOL transfers, or a simple wallet balance checker can all run on standard RPC calls.
When Raw RPC Falls Short
The RPC API has real limitations that hit you the moment you try to build anything non-trivial:
- No complete market-data object — With
encoding: "jsonParsed", getTokenAccountsByOwner includes the token amount and decimals. Names, symbols, logos, prices, and protocol positions require additional resolution. Query the appropriate token program, including Token-2022 where relevant.
- History needs pagination and interpretation —
getSignaturesForAddress returns signatures; getTransaction can return parsed instructions where supported. Retrieving a wallet history still requires pagination and transaction fetches, which may be batched or run with bounded concurrency. It is not necessarily 10,000 sequential requests, and node retention limits still apply.
- No DeFi position parsing — Seeing that a wallet holds a Raydium LP token tells you nothing without decoding the pool state to calculate the underlying token values.
- No price data — RPC has zero concept of what a token is worth.
- Provider limits — Request rate, history retention, and method availability vary. Handle 429, timeouts, and JSON-RPC errors explicitly instead of assuming a successful HTTP response contains usable data.
This is where enhanced and data APIs come in.
Enhanced RPC Providers
Enhanced RPC providers operate RPC infrastructure and add extra features on top of the standard JSON-RPC. They solve the reliability and rate limit problems while adding some data enrichment.
What they typically offer:
- Dedicated endpoints with plan-specific rate limits and any SLA defined in the contract
- Webhook notifications for account changes and transactions
- Transaction parsing that decodes instructions into human-readable events
- Historical data access beyond what standard validators retain
- gRPC streaming for sub-second data feeds
Helius and QuickNode provide examples of this category; Triton is another infrastructure option. Compare their documented methods, streaming products, retention, and regions. Availability of one product does not imply that all enhanced APIs are included in every plan.
Best for: Trading bots, real-time monitoring, dApps that need reliable transaction submission, and anything that needs WebSocket or gRPC streaming.
Limitations: You still need to handle the business logic of combining data from multiple sources. An enhanced RPC provider will tell you a wallet holds 500,000 units of token mint So11111..., but turning that into "5.2 SOL worth $450" requires price data from somewhere else.
Data APIs: Pre-Built Intelligence
Data APIs sit above the RPC layer and do the heavy lifting of indexing, parsing, and enriching blockchain data into something directly usable. Instead of making 50 RPC calls and doing math to figure out a wallet's portfolio value, you make one API call and get back a complete breakdown with USD values, DeFi positions, and historical performance.
Portfolio and Wallet Data
If your app needs to display what a wallet owns, what it is worth, and what it has been doing, a wallet data API is what you want.
CoinStats documents Solana wallet balance and transaction APIs. Check the specific endpoint for pagination, token coverage, pricing, and refresh behavior. A wallet endpoint should not be assumed to include every historical transaction, illiquid token, or DeFi position in one response.
This type of API eliminates the most tedious part of building a portfolio tracker or wallet viewer. Without it, you would need to: query the RPC for all token accounts, look up metadata for each mint, fetch prices from a DEX aggregator, decode LP tokens to find underlying values, check staking protocols for delegated positions, and combine all of it into a single response. A wallet data API can combine parts of that work, with coverage defined by its contract. If you want to see what that data layer looks like as a finished consumer product, our CoinStats review discusses the portfolio product and its coverage.
Best for: Portfolio trackers, tax tools, wallet analytics, user dashboards in dApps.
Trading and Market Data
For trading applications, you need a different slice of data: real-time prices, liquidity depth, volume, and trade execution.
Jupiter provides the standard swap API that most Solana trading bots use. It searches supported routing sources for an available route. Some mints and token extensions are unsupported, and a quoted route is not a guarantee of execution. Birdeye offers market data APIs with OHLCV candles, pair-level volume, and holder analytics.
Best for: Trading bots, DEX aggregators, price feeds, charting applications.
On-Chain Intelligence
Beyond raw market data, some APIs provide derived intelligence — signals, scores, and analytics computed from on-chain patterns.
At MadeOnSol, our API focuses on indexed token and wallet intelligence: tracked KOL trades, multi-wallet coordination, deployer launch history and reputation, and configurable price alerts. Coverage, latency, and available fields depend on the endpoint and plan. Selected feeds are delayed five minutes on BASIC; a paid feed is not an end-to-end execution latency guarantee. This is the type of data that does not exist in any RPC response — it requires continuous indexing, pattern matching, and historical context to produce. If you are building a product on top of this layer rather than just consuming it, our guide to embedding a Solana memecoin data API covers the access patterns and the white-label path.
Best for: Alpha discovery tools, copy-trade systems, research dashboards, signal bots.
