# Zircuit API
> Real-time on-chain data for Zircuit (chain-id 48900) — the zero-knowledge rollup layer-2 on Ethereum with AI-driven Sequencer Level Security. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native ETH balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Zircuit JSON-RPC node — decoded from hex into plain decimals and human-readable ETH so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on the Zircuit ZK rollup.
