# Songbird API
> Live EVM on-chain data for Songbird (chain id 19) — the canary network of the Flare blockchain, whose native token is SGB — served directly from public C-chain 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 SGB balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole SGB 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 Flare and Songbird ecosystem. Live keyless upstream. 5 endpoints.
