KCC Chain API

healthy 4,926 Subscribers

Live on-chain data for KuCoin Community Chain (KCC) — an EVM Layer 1 backed by the KuCoin community — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's KCS balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in KCS, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in KCS, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

KuCoin API

Live spot-market data from KuCoin, one of the largest crypto exchanges and the best-known venue for altcoins, via its public API. KuCoin lists over a thousand trading pairs, so its signature is breadth. Get a pair's full 24-hour snapshot: last price, best bid and ask, high, low, the 24-hour change in price and percent, the base and quote volume, the 24-hour average price and the taker and maker fee. Pull the entire board — every KuCoin pair in one call with its last price and 24-hour change. Get the top of the order book with the spread. Read OHLCV candles at any interval. Live, no key, nothing stored. Distinct from Coinbase, Bitstamp, OKX, Gate.io, Bitfinex, Gemini, Kraken and Bybit venue APIs and from aggregated feeds — this is KuCoin's own ticker, full pair board, order book and candles. Perfect for trading, charting and market-data apps.

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.
