# Kraken Exchange API
> Live market data from the Kraken cryptocurrency exchange, served straight from Kraken's public API — no key, no account, nothing cached. Kraken is one of the oldest and largest crypto exchanges; this reads its order book and trades directly. The ticker endpoint returns the live quote for one or many pairs — the last traded price, the best bid and ask and the spread, the 24-hour volume and VWAP, the 24-hour high, low and open and the change since open, and the 24-hour trade count: XBT/USD trades around its live price with thousands of trades a day. The orderbook endpoint returns the live order book to any depth — the bid and ask price levels with their sizes, the best bid/ask and the spread — the real liquidity behind the price. The ohlc endpoint returns candlestick history at intervals from one minute to two weeks. Pairs can be given the friendly way (BTCUSD, ETHEUR) and it resolves them to Kraken's canonical names. This is the exchange-market-data layer for any trading, charting, arbitrage or bot application. Live from Kraken, nothing stored. Distinct from aggregate-price and other single-exchange APIs — this is Kraken's own ticker, order book and candles. 4 endpoints.
