# Ink API
> Live Ink on-chain data via Blockscout. Ink is Kraken's Ethereum L2 built on the OP Stack; gas and balances are in ETH. Network stats, gas prices, latest blocks, a block by height or hash, address detail with ETH balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.
