Coincheck Exchange API

healthy 4,612 Subscribers

Live market data from Coincheck, one of Japan's largest retail crypto exchanges (Monex Group), straight from its public REST API. This is the single-venue Japanese-Yen (JPY) view. The ticker endpoint returns the live BTC/JPY summary — last price, bid, ask, 24h high/low and 24h volume. The orderbook endpoint returns the live BTC/JPY bid/ask depth with per-level price and size, plus the best bid/ask and the resulting spread. The trades endpoint returns the most recent executed trades for any listed pair, with price, amount, side and time. The rate endpoint returns the current Japanese-Yen price of any listed coin (BTC, ETH, XRP, ETC …). Together they answer "what does crypto cost in Japanese Yen on Coincheck right now, how deep is the BTC book, and what just traded" — a single-venue JPY-denominated exchange view, distinct from the aggregated cross-exchange market, whole-market overview and other regional exchange APIs in the catalogue. Live, no key on the upstream, nothing stored.

Deribit API

Live market data from Deribit — the leading crypto options and futures exchange. A keyless, no-account JSON wrapper over Deribit's public v2 API. Read the spot index price for any settlement currency (BTC, ETH, USDC, USDT), pull a full ticker for any instrument — last / mark / index price, best bid-ask, open interest and 8-hour funding for perpetuals, plus mark implied volatility and the greeks (delta, gamma, vega, theta, rho) for options — list the entire active instruments catalog by currency and kind (future, option, spot, combos) with strikes, expiries and contract sizes, and fetch per-currency order-book summaries across all live instruments. The raw exchange feed for derivatives desks, options dashboards, volatility models and trading bots — distinct from analytics products: this is Deribit's own ticker, instrument and book data, decoded into clean JSON.

Coinstore Market Data API

Real-time spot market data from the Coinstore crypto exchange across 480+ trading pairs. Pull 24-hour tickers for all symbols at once or one at a time (last price, 24h open, high and low, best bid and ask with their sizes, percentage change, base and quote volume); read a lightweight latest-price feed for every actively traded pair; inspect full order-book depth with best bid, best ask, computed spread and the last traded price; and stream the most recent trades with price, size and taker side. Symbols are plain pairs such as BTCUSDT or ETHUSDT. A short protective cache keeps responses fast while staying within a few seconds of the exchange. Distinct from our perpetual-futures exchange feeds (BitMEX, BloFin, Bitunix, Phemex, WEEX): this surfaces the Coinstore spot order book and ticker tape specifically.

WEEX Market Data API

Real-time perpetual-futures market data from the WEEX crypto exchange. List every live perpetual contract with its underlying index, quote and settle currency, contract value, tick size and size increment; pull 24-hour tickers for all 700+ contracts at once or one at a time (last price, best bid and ask, 24h high and low, traded and base volume, percentage change, mark price and index price); read full order-book depth with best bid, best ask and computed spread; and stream the most recent trades with price, size, notional value and side. Symbols use the WEEX cmt_ prefix (cmt_btcusdt) and accept either form (BTCUSDT or cmt_btcusdt). A short protective cache keeps responses fast while staying within a few seconds of the exchange. Distinct from our BitMEX, BloFin, Bitunix and Phemex exchange feeds: this surfaces the WEEX order book, ticker tape and contract registry specifically.

Phemex Market Data API

Real-time perpetual-futures market data from the Phemex crypto exchange. List every live perpetual product with its base, quote and settle currency, tick size and maximum leverage; pull 24-hour tickers for all 800+ symbols at once or one at a time (last, mark and index price, 24h open/high/low, percentage change, traded volume, turnover, open interest and the current and predicted funding rate); read full order-book depth with best bid, best ask and computed spread; and stream the most recent trades with price, size, side and nanosecond timestamp. All prices and quantities are returned already de-scaled into real human-readable units, so there is no exponent arithmetic to do on your side. A short protective cache keeps responses fast while staying within a few seconds of the exchange. Distinct from our BitMEX, BloFin and Bitunix exchange feeds: this surfaces the Phemex order book, ticker tape and product registry specifically.
