Get coin OHLCV

Growth This endpoint requires the growth plan or higher. Free, Basic and Startup plans can use preview access.

Get OHLCV (Open High Low Close Volume) data for the coin throughout time.

Preview access

Free, Basic and Startup plans can test this endpoint with five successful requests per account per UTC day. Use the documented endpoint URL with your existing API key. Preview access is applied automatically. The allowance resets at 00:00 UTC.

All API keys, resource IDs, query parameters and pagination requests share this endpoint's allowance for your account. Failed requests do not consume the preview allowance. Successful previews also count toward your normal API usage, and your plan's result, historical-window and rate limits still apply. See endpoint previews for limits, response headers and quota errors.

This endpoint has two modes:

Latest candles (default): without a from parameter, the endpoint returns the most recent limit candles for the chosen interval — the classic behaviour.
Historical window: supply a from (and optional to) timestamp to fetch a specific time range instead. Minute-resolution history is available all the way back to December 2018, so you can pull deep historical candlestick data and page through arbitrarily long ranges.

Path parameters

Parameter	Description
uuid `String`	UUID of the coin you want to request the OHLCV data for.

Query parameters

Parameter	Description
interval (optional) `String`	The interval determines the time period over which each OHLC item is determined. Default value: day Allowed values: minute 5minutes hour 8hours day week month Example: `https://api.coinranking.com/v2/coin/Qwsogvtv82FCd/ohlcv?interval=hour`
limit (optional) `Number`	Limit. Limit the amount of time periods for which the OHLCV data is retrieved. For example, when interval=hour and limit is 10, data will be returned for the last 10 hours. Production access requires the Growth plan or higher. Free previews are limited to 100 results per response. All other plans can receive up to 5000 results per response, including previews. Ignored in historical window mode (when `from` is supplied); windows are instead capped at 1440 candles per response and paged with `data.paging.next` — see Fetching historical ranges. Default value: 50 Size range: 0-5000 Example: `https://api.coinranking.com/v2/coin/Qwsogvtv82FCd/ohlcv?limit=10`
from (optional) `Number`	Start of the historical window as a Unix timestamp in seconds. Supplying `from` switches the endpoint into historical window mode: instead of the latest `limit` candles, it returns candles for the requested time range. `from` is snapped down to the start of its interval, so the bucket containing `from` is included. Minute-resolution history is available back to December 2018. When omitted, the endpoint stays in the default latest-candles mode. Size range: 0-4102444800 Example: `https://api.coinranking.com/v2/coin/Qwsogvtv82FCd/ohlcv?interval=hour&from=1614556800&to=1617235200`
to (optional) `Number`	End of the historical window as a Unix timestamp in seconds. The window is half-open: candles are returned for every interval bucket that starts before `to`. Unlike `from`, `to` is not snapped, so if it falls mid-interval the bucket it lands in is still returned (effectively rounding `to` up to the next boundary); only a candle starting exactly at `to` is excluded. Requires `from`, and must be greater than `from`. When omitted, the window runs up to the present moment. Default value: now Size range: 0-4102444800 Example: `https://api.coinranking.com/v2/coin/Qwsogvtv82FCd/ohlcv?interval=hour&from=1614556800&to=1617235200`
referenceCurrencyUuid (optional) `String`	UUID of coin (either fiat or crypto), in which all the prices are calculated. Defaults to US Dollar, but you can use any coin. You can find UUIDs for reference currencies in any coin endpoint, including a convenient dedicated reference currency endpoint Note: When using a reference currency, the OHLC values are converted from USD-based calculations rather than recalculated from raw trading data. Since reference currency exchange rates fluctuate during the time period this means: The Open or Close values might be higher than the High or lower than the Low For true OHLC data in a specific currency pair, use USD as the reference currency or subscribe to the realtime rates for both the coin and the intended reference currency and calculate the OHLC values yourself Default value: yhjMzLPhuIDl Example: `https://api.coinranking.com/v2/coin/Qwsogvtv82FCd/ohlcv?referenceCurrencyUuid=5k-_VTxqtCEI`

Fetching historical ranges

Supplying a from timestamp puts the endpoint in historical window mode. It returns the candles that fall inside the half-open range [from, to) for the chosen interval, ordered newest-first, with minute-resolution data available back to December 2018.

The 1440-candle cap and paging

A single response returns at most 1440 candles. When the response does not cover the whole requested window, it is truncated to the portion nearest from and a continuation cursor is returned on data.paging.next (a Unix timestamp in seconds). To fetch the next page, repeat the request with from set to that value and the same to. When the window has been returned in full, data.paging.next is null.

Always drive paging from data.paging.next, not from the candle count. A page can contain fewer than 1440 candles and still have more to follow — a non-null next always means there is another page. Keep requesting until next is null.

Walking a range this way is gapless and overlap-free, and identical requests always return identical candles. Historical windows are immutable and returned with a long cache lifetime (Cache-Control: max-age=3600; recent windows use max-age=60), so responses can be cached aggressively.

# 1) Request a wide range
GET /v2/coin/Qwsogvtv82FCd/ohlcv?interval=minute&from=1609459200&to=1612137600

# 2) Response was truncated, e.g. data.paging.next = 1609545600
#    Fetch the next page by advancing `from` to that value:
GET /v2/coin/Qwsogvtv82FCd/ohlcv?interval=minute&from=1609545600&to=1612137600

# 3) Keep going until data.paging.next is null

Data availability in historical candles

Older candles carry less detail than recent ones, because the historical archive did not always store every field:

avg is null throughout deep history — it is not reconstructable from the archived data.
For older periods where only the closing price was preserved, open, high and low are derived from the close, so those candles are flat (all four equal). They are null only for buckets that have no data at all (where close is null too).
intervalVolume is null for periods where the source did not record interval volume.
24hVolume in a historical candle is the rolling 24-hour volume recorded at the end of that bucket — a point-in-time snapshot, never a sum of the interval.

Intervals and access

All intervals (minute through month) can be queried with from/to. Production access requires the Growth plan or higher. Free, Basic and Startup plans can use preview access within their plan’s historical window. Historical requests are subject to a daily fair-use quota, and exceeding it returns a 429 response (see Error response).

Response fields

Property	Description
status `String`	Status of the request Allowed values: success
data `Object`
data.ohlc `Object[]`	List of OHLC items
data.ohlc.startingAt `Number`	An Epoch timestamp in seconds marking the start of the time period on which the OHLC values are based.
data.ohlc.endingAt `Number`	An Epoch timestamp in seconds marking the end of the time period (exclusive).
data.ohlc.open `String/null`	Opening price of the coin for the time period in the reference currency
data.ohlc.high `String/null`	Highest USD price of the coin during the time period in the reference currency. When using non-USD reference currencies, the highest USD price is directly converted to the reference currency. Since the reference currency itself can fluctuate against the US Dollar, the High is not necessarily the highest price in the chosen reference currency.
data.ohlc.low `String/null`	Lowest USD price of the coin during the time period in the reference currency. When using non-USD reference currencies, the lowest USD price is directly converted to the reference currency. Since the reference currency itself can fluctuate against the US Dollar, the Low is not necessarily the lowest price in the chosen reference currency.
data.ohlc.close `String/null`	Closing price of the coin for the time period in the reference currency
data.ohlc.avg `String/null`	Average price of the coin over the time period. Always `null` for deep historical candles, where it is not reconstructable.
data.ohlc.24hVolume `String/null`	Total 24h volume of the coin in the reference currency. In historical candles this is a rolling 24-hour snapshot taken at the end of the bucket, not a sum of the interval.
data.ohlc.intervalVolume `String/null`	Total volume of the coin for the specified time interval in the reference currency. In the default latest-candles mode this is populated for the week and month intervals only. In historical window mode it is also populated for finer intervals where the data source recorded interval volume; otherwise it is `null`.
data.paging `Object`	Only present in historical window mode (when `from` is supplied).
data.paging.next `Number/null`	Epoch timestamp in seconds to use as the next `from` value to continue the range, or `null` when the window has been returned in full. See Fetching historical ranges.

Error responses

Error	Description
FORBIDDEN `Object`	Returned by the gateway in the `code` field when endpoint access is denied. Production access requires the Growth plan or higher. Free, Basic and Startup plans can use preview access. Read the identifier defensively as `body.type \|\| body.code`. Upgrade your plan.

Error	Description
COIN_NOT_FOUND `Object`	The coin could not be found. Try another UUID

Error	Description
VALIDATION_ERROR `Object`	The request could not be validated. The response should provide more details. For window mode, common causes are `to` without `from`, or `to` not greater than `from`.
REFERENCE_UNAVAILABLE `Object`	The reference currency used in the request is not available. Choose another UUID.

Error	Description
TOO_MANY_REQUESTS `Object`	The daily fair-use quota for deep-history requests has been reached, or too many history requests are in flight at once. Slow down and retry, or contact support.
