Solana JSON RPC

Overview

Solana’s JSON-RPC API queries the Solana blockchain — balances, blocks, and transactions. It’s a POST-only RPC (GET returns an info page, verified).

Quick Start

Send JSON-RPC POST (the public mainnet endpoint is operated by Triton One):

curl -X POST "https://api.mainnet-beta.solana.com" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "getBalance", "params": ["11111111111111111111111111111111"]}'

{ "jsonrpc": "2.0", "result": { "context": { "slot": 123456789 }, "value": 0 }, "id": 1 }

Authentication

None for public RPC (rate-limited); paid RPC providers for production.

• Methods: getBalance, getSlot, getBlock, getTransaction, getTokenAccountsByOwner.
