# Solana Portal API

> Access raw Solana blockchain data — blocks, transactions, instructions, balances, rewards — through the SQD Portal HTTP API for high-throughput streaming.

Portal provides direct access to raw Solana blockchain data. Query slots, transactions, instructions, logs, token balances, and rewards with performance that scales beyond traditional RPC limitations.
