#coinbase

Live market data straight from Coinbase's public Exchange API — one of the largest and most trusted regulated crypto venues, exposed as clean JSON with no key and nothing cached. The products endpoint lists Coinbase's roughly 800 trading pairs with their base and quote currency, price and size increments, minimum order size and trading status, filterable by quote currency. The ticker endpoint returns a pair's live snapshot: the last trade price, the best bid and ask, the bid-ask spread in absolute and percentage terms, and the 24-hour base volume — BTC-USD trading around $63,300 with a one-cent spread. The stats endpoint returns the rolling 24-hour open, high, low and last with the 24-hour and 30-day volume and the computed 24-hour percentage change. The orderbook endpoint returns the top of book — the best bid and ask at level 1, or the aggregated top of the book at level 2 with configurable depth — together with the spread. The candles endpoint returns recent OHLC candles at a granularity you choose, from one minute to one day, for charting and backtesting. Everything is Coinbase's live venue data, nothing stored. This is the Coinbase price-and-liquidity layer for any trading, charting, arbitrage, portfolio or market-data app. Live from Coinbase Exchange. Distinct from Binance and Kraken venue APIs and from aggregated price feeds — this is Coinbase's own order book and tape. 6 endpoints, no key on our side, real-time.

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.
