# Plume API
> Live Plume on-chain data via Blockscout. Plume is a real-world-asset (RWA) focused Ethereum L2; gas and balances are in PLUME. Network stats, gas prices, latest blocks, a block by height or hash, address detail with PLUME balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.
