#spot-price

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.

Built for trading, jewellery, treasury and dashboard apps. The commodities and precious-metals layer, live and key-free — distinct from generic ticker-quote APIs.
