RPC

Standard Solana JSON-RPC interface for on-demand queries: balances, transaction history, account state, sending transactions.

// updated 2026-06-04

Standard Solana JSON-RPC interface for on-demand queries against the blockchain.

NOTE

Token auth. Send your token as x-token or Authorization: Bearer on every request - see Authentication. A request without a valid token is rejected with 401.

What it's for

Wallets reading balances, explorers showing transaction history, dashboards rendering account state, batch indexers pulling historical data, sending signed transactions. Anything that asks the chain a question and gets an answer.

For a continuous stream of events instead of one-off queries, see gRPC or WebSocket.
