Live on-chain data from the Nervos Common Knowledge Base (CKB) via the official Nervos explorer — clean JSON, no cache. Nervos CKB is a proof-of-work Layer-1 built on the Cell model — a generalised UTXO where every cell can hold state and code — secured by the Eaglesong hash and governed in epochs, with a native state-rent / deposit system (NervosDAO) that pays interest for locking CKB. Read the chain state (tip block, current epoch, block time, difficulty and hashrate); browse the most recent blocks with miner and reward; fetch a single block by number or hash; look up an address's CKB balance, its NervosDAO deposit and compensation, live-cell count and UDT token accounts; or resolve a transaction's block, fee and type. Read live from Nervos, nothing stored. This is Nervos CKB's own Cell-model, NervosDAO and PoW layer — distinct from the Bitcoin, Decred, Ergo and other on-chain APIs and from price feeds.

Live on-chain data from the Ergo (ERG) blockchain via the public Ergo Platform explorer — clean JSON, no cache. Ergo is a proof-of-work cryptocurrency built on the extended-UTXO (eUTXO) model with first-class native tokens, Sigma-protocol smart contracts and storage rent — a distinctly different design from account-based chains. Read the network head (best block height, mining difficulty, miner reward); browse the most recent blocks with their miner, size, difficulty and reward; fetch a single block by header id; look up any address's confirmed ERG balance and every native token it holds; or resolve a native token's id, name, decimals, emission amount and description. Read live from Ergo, nothing stored. This is Ergo's own extended-UTXO chain, native-token and Autolykos-PoW layer — distinct from the Bitcoin, Decred, EOS, Internet Computer and other on-chain APIs and from price feeds.

Live Ethereum Classic on-chain data via Blockscout. Ethereum Classic (ETC) is the original proof-of-work Ethereum chain; gas and balances are in ETC. Network stats, gas prices, latest blocks, a block by height or hash, address detail with ETC balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.
