# Rollux API
> Live EVM on-chain data for Rollux (chain id 570) — the Syscoin Layer-2 secured by Bitcoin merge-mining, whose gas token is SYS — served directly from public Layer-2 JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the SYS balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole SYS with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Syscoin and Rollux ecosystem. Live keyless upstream. 5 endpoints.
