Documentation

Overview

Sum / mean / min / max for a chosen metric over a date range, or the number of days crossing a threshold per a comparator (op=count).

Authentication

Every request requires the x-api-key header. Credits used and remaining quota are returned in response headers (x-api-credits-used, x-api-remaining-credits, x-rate-limit-*).

Request

GET https://api.apikodu.com/api/v1/weather/aggregate?latitude=39.92&longitude=32.87&fromDate=2026-06-01&toDate=2026-06-30&metric=precip&op=sum

GET query.

Parameters

Name	Type	Required	Default	Options	Description
`latitude`	number	* Required	—	—	Point latitude -90..90.
`longitude`	number	* Required	—	—	Point longitude -180..180.
`fromDate`	string	* Required	`2026-06-01`	—	Start YYYY-MM-DD. Range ≤ 366 days.
`toDate`	string	* Required	`2026-06-30`	—	End YYYY-MM-DD. At most yesterday (UTC): aggregates use observed days only.
`metric`	string	* Required	`precip`	`temp` `tmin` `tmax` `precip` `snow` `wind` `humidity` `et0`	temp, tmin, tmax, precip, snow, wind, humidity, et0.
`op`	string	* Required	`sum`	`sum` `mean` `min` `max` `count`	sum, mean, min, max, count. count requires threshold.
`threshold`	number	Optional	—	—	Threshold. Only for op=count.
`comparator`	string	Optional	`gt`	`gt` `gte` `lt` `lte`	gt, gte, lt, lte. Default gt. Only for op=count.

Response

Name	Type	Description
`metric`	string	Metric used.
`op`	string	Operation used.
`threshold`	number	Threshold when op=count, else null.
`comparator`	string	Comparator when op=count, else null.
`fromDate`	string	Window start.
`toDate`	string	Window end.
`daysTotal`	integer	Calendar days in the window.
`daysWithData`	integer	Days the metric could be computed.
`missingCount`	integer	Days without data.
`value`	number	sum/mean/min/max result. null when op=count.
`count`	integer	Days crossing the threshold when op=count. null otherwise.
`unit`	string	Result unit (°C, mm, km/h, %). days when op=count.
`gridLatitude`	number	Latitude of the 0.1° grid corner around the request (interpolation reference).
`gridLongitude`	number	Longitude of the 0.1° grid corner.
`gridInterpolated`	boolean	true: values bilinearly blended from the 4 surrounding cells. false: single cell.
`sources`	array	Data sources that contributed: copernicus-era5-land, open-meteo, openweather, met-norway. For past days (older than about a week) Copernicus ERA5 / ERA5-Land takes precedence; UV, precipitation probability and the weather code of wet hours / days are derived from ERA5-Land variables, wind gust comes from ERA5 (0.25°); cloud cover and the weather code of dry hours / days are filled from other sources when available. At coastal / sea points ERA5-Land values come from the nearest land grid point.
`disclaimer`	string	Decision-support disclaimer and source attribution.

Errors

HTTP	code	Description
`400`	`-257`	latitude/longitude missing or out of range (lat -90..90, lon -180..180).
`400`	`-258`	fromDate/toDate not YYYY-MM-DD, range exceeds 366 days, or outside the last 2 years / after yesterday.
`400`	`-259`	granularity/days/hours/metric/op/comparator is invalid.
`429`	`-316`	Daily new location (cell) limit (50) reached. Previously requested locations keep working; new locations next day (UTC). Retry-After header gives seconds until end of day.
`503`	`-261`	No stored weather for this location yet. Cells were created; the collector is filling them. Retry shortly.
`401`	`-100`	x-api-key is missing, empty, malformed, inactive, banned, expired, IP-restricted, or not allowed for this API.
`429`	`-221`	Per-minute request limit exceeded. Response headers: x-rate-limit-limit, x-rate-limit-remaining, x-rate-limit-reset.
`429`	—	Package credit quota cannot cover this request. Body may be { error, limit, currentUsage, requestCost } (no code field).
`500`	`-1`	Unexpected server error. message is a generic error text without technical details.

Notes

Success body is { data: { ... } }. Error body is { code, message }. code is an ApiResponseCode enum value (negative integer).
