Solana (SOL) API Documentation

Solana

Solana (SOL) is a proof-of-stake Layer 1 that uses Proof of History as a cryptographic clock alongside validator voting, with Mainnet Beta launched on March 16, 2020. Programs are commonly written in Rust and compiled to sBPF bytecode, while mutable state lives in separate accounts that full nodes execute against and replicate with blocks and transactions. This account-and-program model makes accounts, instructions, signatures, and slots the core primitives exposed to applications rather than EVM-style contract storage.

Solana API Methods and Endpoints

NOWNodes exposes Solana's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, and WSS (WebSocket) for real-time subscriptions and events.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
