Binance Market Data API

healthy 3,495 Subscribers

Live Binance crypto exchange market data as an API — clean JSON, no key. Get the current price of any trading pair, full 24-hour ticker statistics (open, high, low, last, price change, weighted average, best bid/ask and volume), candlesticks (klines) for any interval from one minute to one month, the live order book (bids and asks with quantities), recent trades, the current average price, and the full list of trading pairs filtered by quote asset. Live data straight from Binance's public market endpoints. Distinct from aggregate coin-market data: this is exchange-native trading data — order book, candles and live ticks — ideal for trading bots, price feeds, charts, backtesting and crypto dashboards. 7 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

Crypto Volume API

Live most-traded crypto pairs by 24-hour spot volume as an API, powered by Binance. It ranks the trading pairs by their 24-hour quote volume — where the real liquidity and activity is right now — with each pair's last price, daily change, 24-hour high and low, base and quote volume, and the number of trades. Rank by any quote currency (USDT, BTC, ETH, USDC), or look a single pair up for its full 24-hour stats. The spot-volume and market-activity leaderboard for trading, screening and dashboard apps. Live, no key, no cache. Distinct from price-change movers and from DEX-volume APIs — this is centralised-exchange spot trading volume.

Crypto Volatility API

Live crypto realized (historical) volatility as an API, computed from Binance daily candles. For any coin it returns the annualized realized volatility over the 7-, 30- and 90-day windows — the standard deviation of daily log returns, annualized over 365 days — the average true range as a percent of price, the current price, and a plain-language regime label (low, normal, high or extreme). It can also rank a basket of major coins by their 30-day volatility, so you can see at a glance which assets are calm and which are wild. The volatility layer that options pricing, position sizing and risk dashboards need. Live, no key, no cache. Distinct from price, OHLC and drawdown APIs — this is the realized-volatility analytic.

Crypto Arbitrage API

Live crypto cross-exchange price comparison and arbitrage spread — the spot price of a coin on the major centralised exchanges at once, served straight from each exchange's public ticker. For any base coin it fetches the spot price from Binance, OKX, Bybit, KuCoin and Coinbase in parallel, returns the per-exchange price table, identifies the cheapest venue to buy and the most expensive to sell, and computes the spread between them — absolute and percentage — the headline cross-exchange arbitrage gap. Get the full price table, the best buy/sell opportunity, or the list of exchanges. Live, no key, no cache. Quotes are USDT (Binance/OKX/Bybit/KuCoin) or USD (Coinbase), within a few basis points. A price-discovery and arbitrage layer for trading, analytics and dashboard apps. Distinct from single-exchange price and OHLC APIs — this is the cross-exchange arbitrage view.

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.
