Ethereum On-Chain API
Live Ethereum mainnet on-chain data as an API, built on the open Blockscout explorer — a different layer from market-price feeds. Pull network stats (total blocks and transactions, ETH price, market cap and live gas usage), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its ETH balance, ENS name and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD exchange rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for wallets, block explorers, gas trackers, DeFi dashboards and crypto analytics.
