Solana APIs are applications and services that enable interaction with the Solana blockchain by acting as messengers between software systems. These tools allow developers to retrieve wallet information, check SOL balances, access token holdings, fetch transaction history, and retrieve NFT data and ownership information.
Infrastructure and Node Providers
QuickNode offers low-latency infrastructure designed to scale decentralized applications on Solana. The service combines traditional node infrastructure with advanced data products and transaction tools, serving developers building multi-chain applications, NFT platforms, DeFi systems, and enterprise blockchain solutions.
Helius provides high-performance tools with a user-friendly interface that simplifies blockchain interactions. The platform includes enhanced Solana RPC APIs, the Digital Asset Standard API for NFT and token data, real-time transaction and account monitoring, and webhooks for blockchain event notifications.
Alchemy delivers real-time data and Solana infrastructure through JSON-RPC and WebSocket connections, alongside Yellowstone gRPC for streaming live blockchain data and FAS and Photon APIs for tokens and NFTs. The service supports Solana Mainnet and Devnet with 99.99% reliability, multi-region infrastructure, and automatic failover.
Chainstack is a node provider offering both shared and dedicated nodes across more than 70 blockchains with geo-distributed infrastructure for reduced latency. The platform provides a free tier for development and testing, with paid plans scaling based on throughput and node type rather than per-call credits.
Specialized Data and Swap Services
ChangeNOW focuses on crypto swaps rather than direct blockchain data access. The service allows wallets, decentralized applications, exchanges, and payment platforms to integrate in-app swaps without building their own exchange logic. ChangeNOW supports 1,500 assets across 110+ blockchains with over 2.25 million exchange pairs sourced from centralized and decentralized exchanges, reporting 99.99% availability and a 350-millisecond response time.
CoinAPI aggregates data from 300 exchanges through a single interface, providing developers access to real-time and historical SOL trades, quotes, order books, and OHLCV data. The service offers pay-as-you-go access with $25 in monthly free credits, with fixed plans starting at $79 per month.
Multi-Chain and Cross-Protocol Platforms
Moralis supports both EVM chains and Solana, focusing on making blockchain data accessible through simple REST endpoints. The platform provides token data, pricing, NFT metadata, and normalized DeFi positions across major protocols via single API calls.
CoinStats delivers actionable information for developers across more than 120 blockchains and 10,000+ DeFi protocols. The service serves wallets, tax tools, portfolio trackers, and dashboards with a credit-based pricing model. The free plan includes 50,000 monthly credits and up to 5 requests per second, with paid plans beginning at $49 per month.
The growing Solana developer ecosystem continues to create demand for reliable APIs that simplify blockchain connectivity and data access, enabling developers to read data from and interact with the Solana blockchain.
