Crypto OHLCV API

Coinranking API OHLCV endpoint returns candles at seven intervals: minute, 5minutes, hour, 8hours, day, week and month. Each candle carries startingAt, endingAt, open, high, low, close, average, the rolling 24-hour volume and, where recorded, the volume traded inside the interval. See the OHLCV documentation.

Minute-resolution OHLCV history from Coinranking is available back to December 2018, and all seven intervals accept a from/to window. Pass from and optionally to as epoch seconds to fetch a window; each response returns up to 1,440 candles and a data.paging.next cursor to continue, so a multi-year minute series is a loop, not a limit.

OHLCV candles are a Professional endpoint on Coinranking API, at $199 a month with a 30-day free trial. Because the endpoint is Professional-only, the Free and Startup result limits do not apply: latest-candles requests return up to 5,000 candles, and historical windows page in blocks of 1,440. Deep-history requests are subject to a daily fair-use quota.

Yes, with a caveat the docs state plainly. Passing referenceCurrencyUuid converts each candle's USD open, high, low and close at the reference currency's rate, so in a volatile reference currency the open or close can sit outside the high–low range. For true OHLC in another pair, keep USD, or build candles yourself from the WebSocket rates of both assets.

No, and the docs say which fields differ. In deep history avg is null, intervalVolume is null where the source did not record it, and for periods where only the close was preserved the open, high and low equal the close. Candles with no data at all have null prices. Recent candles carry every field.

Yes. Coinranking futures coin OHLCV endpoint returns candles for a coin's perpetual futures markets, alongside open interest and funding rate endpoints, on the Professional plan. Details are on the Crypto Futures API page.
