# Oasis Sapphire API
> Real-time on-chain data for Oasis Sapphire (chain-id 23294) — the confidential EVM-compatible ParaTime on the Oasis Network that brings on-chain privacy to smart contracts, with ROSE as its native token. 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 ROSE balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Sapphire JSON-RPC node — decoded from hex into plain decimals and human-readable ROSE so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on Oasis Sapphire.
