Metis Chain API

healthy 4,213 Subscribers

Live on-chain data for Metis (Andromeda) mainnet via Blockscout — no key. Read network stats (block height, total transactions, METIS price, market cap), a gas oracle in gwei, the most recent blocks and full block detail by height or hash, any address balance and contract info, full transaction detail, ERC-20 token detail by contract, and a universal search across addresses, tokens, blocks and transactions. Real Layer-2 chain data with the rotating proxy as automatic fallback — 9 endpoints. Ideal for wallets, explorers, portfolio trackers, analytics dashboards and on-chain monitoring on Metis.

Chain Stats API

Live blockchain network statistics across 18 chains, from the public Blockchair feed. Get one network's full stats — price, market cap and dominance, block height, 24h transactions, circulating supply, difficulty, hashrate, mempool size and average fee; compare the major chains side by side, ranked by market cap; and read a chain's mempool congestion (pending transactions, size and fees). A multi-chain network-stats layer — distinct from single-coin price feeds and Bitcoin-only on-chain APIs: it answers how each blockchain is performing right now and how they compare. Live, with a 10-minute upstream cache.

Dash On-Chain API

Live on-chain data from the Dash (DASH) blockchain — a payments-focused cryptocurrency — via the public Dash Insight explorer, clean JSON and no cache. Dash uses X11 proof-of-work plus a second tier of collateralised masternodes that power InstantSend (near-instant locked payments) and ChainLocks, and an on-chain treasury that funds proposals. Read the chain state (block height, difficulty, peer connections, protocol version and relay fee); fetch a block by height or hash; look up an address's DASH balance, total received and sent and transaction count; or resolve a transaction's block, value, fee, input/output counts and its InstantSend lock status. Read live from Dash, nothing stored. This is Dash's own X11, masternode-tier and InstantSend ledger — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.

Conflux On-Chain API

Live on-chain data from the Conflux (CFX) network — a high-throughput Layer-1 that orders blocks with the Tree-Graph DAG consensus (not a single chain) and runs two spaces: the native Core space (cfx: addresses) and an EVM-compatible eSpace. Served live from a public Conflux Core-space JSON-RPC node as clean JSON. Conflux is distinctive for its storage-collateral model and a built-in proof-of-stake interest rate. Read the chain state (chain id, current epoch, block number, latest-finalized epoch, pending-tx count and the PoS interest rate); the supply (circulating, issued, staked and storage-collateral CFX); a block (the pivot block of an epoch) by epoch number or hash; or a Core-space address's CFX balance and staked balance. Read live from Conflux, nothing cached. This is Conflux's own Tree-Graph, storage-collateral and PoS layer — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.

Nervos CKB On-Chain API

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.
