Solana (SOL) API - Building Your Web3 Dapps

What is Solana (SOL) API?

Solana API is the set of interfaces developers use to interact with the Solana blockchain.  It provides a way for developers to talk to the blockchain without running their own Solana node. Through it, applications gain access to a vast array of functionalities offered by Solana – query on-chain data, manage wallets, and submit transactions.

The core component is the JSON-RPC interface exposed by RPC nodes – servers maintained by the network’s participants or by third-party providers like GetBlock. Instead of syncing a full Solana node, developers or users send standard HTTP, gRPC, or WebSocket requests to an RPC endpoint and get structured responses back.

API access makes it much easier to build apps and programs on Solana without having to manage the low-level network infrastructure. For developers of crypto wallets, DeFi protocols, AI-powered applications, or analytics dashboards, the API is an entry point into Solana’s on-chain state.

Why use Solana (SOL) API?

In traditional blockchain networks, developers often have to run so called nodes to interact with any decentralized network, which can be resource-intensive. With the RPC interface, developers can bypass this requirement and immediately interact with the network using simple API calls.

These will include all types of interaction with Solana:

  • Read data: Receive information stored on the blockchain programmatically such as transaction history, account balances, block details, and other chain information

  • Broadcast data: Submit new transactions, deploy programs, interact with programs, or propagate other types of on-chain writes

  • Build applications: Combine reads and writes to create wallets, trading bots, explorers, and any other software that interacts with Solana directly

All of this happens through simple API calls, so developers can skip node management entirely and go straight to building. This ease of access encourages broader participation from developers and fosters innovation within the ecosystem.

Key Features of Solana API

Solana’s RPC API supports the main tasks developers need when building blockchain apps. The table below groups them by function:

Feature

Description

Example Use Cases

Real-time blockchain data

Direct retrieval of transactions, account details, block and network stats

Explorers, analytics, trading platforms, audit tools

Wallet management

Address generation, balance checks, fund transfers, and transaction history.

Payment gateways, exchanges, portfolio trackers

Token operations

SPL and Token-2022 transfers, token account lookups, metadata and mint info

Wallets, NFT marketplaces, token trading platforms

Program interaction

Calling on-chain programs, simulating transactions, reading program-derived accounts

DeFi protocols, gaming, DAOs

Transaction processing

Transaction creation, signing, priority fee optimization, and broadcasting.

DeFi platforms, trading bots, wallet apps, bridges

Subscriptions

Real-time notifications for account changes, slot updates, and log events

Trading bots, live dashboards, monitoring, indexing services

Address validation

Verify address format and validity before processing transactions.

Wallets, exchanges, payment systems

By exposing these functions through RPC nodes, Solana makes it easier to build applications that interact directly with the network.

How to Get Started with Solana (SOL) API

GetBlock makes accessing Solana's infrastructure easy and available to developers of all levels. Users can quickly start using the services to build applications by following three simple steps.

Authentication

Sign up on the GetBlock platform using a MetaMask wallet, GitHub account, or email. After signing up, new account gets a free tier with 50,000 daily compute units (CUs), which is enough for personal projects or initial testing.

Acquiring an Endpoint

For the next step, proceed to the widget on the account dashboard to generate an endpoint – a URL that developers use to connect to the Solana infrastructure provided by GetBlock. Users can then copy and use this URL in their code.

Integrating Solana API

To show an example of using the obtained endpoint, let's make a POST request to the GetBlock API, querying the balance of a SOL account ("BSfyn7CncEtBfdjJcXUoPMEcgsRKKZmua9yRr3LUXrvq") on the mainnet.

curl -XPOST "https://go.getblock.io/<ACCESS-TOKEN>/" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"getBalance","params":["BSfyn7CncEtBfdjJcXUoPMEcgsRKKZmua9yRr3LUXrvq"]}'

The response includes a context object with the current slot and the current account balance in lamports (1 SOL = 1,000,000,000 lamports).

Available Solana API Methods

The list below shows the most frequently used methods, in addition to getBalance method, accessible via Solana's JSON-RPC protocol.

  • getAccountInfo: Retrieves detailed information associated with an account, including its balance, owner program, and whether it is executable

  • getLatestBlockhash: Provides the most recent blockhash, which you need to include in every transaction before signing and sending

  • getBlock: Returns full data for one specific block

  • getTransaction: Returns information about any transaction and returns its status

  • sendTransaction: Submits signed transactions to the blockchain network for processing

GetBlock's SOL documentation covers these and other supported methods with detailed explanations and examples of how to use them in code.

Higher-Level Solana Data APIs

JSON-RPC methods return raw blockchain state. Some apps need data already aggregated and ready to use – for example, portfolio views, pricing data, or activity across multiple DeFi protocols.

CoinStats Solana API is one of the services that works at this layer. It serves wallet data, historical prices, and DeFi positions through REST endpoints, and also offers an MCP Server for AI agents and LLM-based tools. The service uses a credit-based pricing but offers a free tier as well.

Both layers tend to coexist in production. Raw RPC handles transaction signing, on-chain queries, and custom indexing. Aggregated data APIs handle the parts that would otherwise require building indexers from scratch.

Pricing and Plans for Solana (SOL) API

GetBlock ensures that there is a suitable plan available for every use case, whether it's for hobbyist developers, startups, enterprises, or large-scale projects.

Solana API pricing examples

One popular plan is “shared” infrastructure where the resources of a single node are used by multiple clients. Pricing options include:

  • Free tariff with limited CUs (50k/day)

  • CU packages with higher rate limits

  • Custom plans at a fixed monthly fee for higher volume usage

This option is beneficial for both individuals or small-scale projects looking to explore the platform's capabilities or start with limited resources and enterprise teams that need a higher level of control over their subscription.

Dedicated SOL API

As applications grow in popularity and usage, developers may need to consider scaling options to accommodate increased demand for API calls. For this case, GetBlock deploys private nodes that feature:

  • No limitations on rates and requests

  • Flexibility in choosing interfaces and specific node specs

  • Access to deeper data and transactions tools

  • Tailored node setup

This plan ensures that applications can scale seamlessly as they require more resources.

Enterprise SOL solutions

For large-scale businesses or applications that require extra resources and features beyond what standard packages provide, ​​GetBlock offers specialized solutions.

With this plan, clients benefit from advanced analytical and performance optimization tools, priority support, and flexibility in deploying nodes outside the scope of listed protocols.

In summary, Enterprise API guarantees the best service for growing businesses.
