bitFlyer API
Live spot market data from bitFlyer, one of Japan's largest and longest-running crypto exchanges — served straight from its public API, no key, nothing cached. Get a product's last traded price, best bid/ask, 24h volume and order-book depth (in Japanese yen); read the live order book with the mid price and top bids and asks; and list bitFlyer's spot and FX products. A distinct Japanese venue with yen pricing, separate from other exchange feeds. Products are BASE_QUOTE (e.g. BTC_JPY).
