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.

KCC Chain API

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).

AscendEX Exchange API

Live spot market data from AscendEX (formerly BitMax), a global crypto exchange, served straight from its public API with no key and nothing cached. The ticker endpoint returns a market's last price, open, 24-hour high and low, 24-hour change, best bid and ask and volume. The tickers endpoint returns every spot market for a quote currency ranked by 24-hour volume, so one call surfaces the most-traded pairs on the venue. The markets endpoint lists the tradable pairs with their tick and lot size and minimum and maximum notional. The book endpoint returns live order-book depth — every bid and ask level with price and amount, plus the best bid/ask and the spread. Everything is read live from AscendEX on each request, nothing stored. A distinct global venue, separate from the other exchange feeds on the marketplace. Markets are written BASE/QUOTE; BTC_USDT is also accepted. Ideal for trading bots, price tickers, arbitrage scanners, portfolio trackers and market dashboards. Live, no key. 4 spot endpoints. For candles or perpetuals use an OHLC or derivatives API.

A distinct global venue, separate from the other exchange feeds on the marketplace. Ideal for trading bots, price tickers, arbitrage scanners, portfolio trackers and market dashboards.
