Examples

Example 1

Retrieving weather forecast for a given location for the next 9 days.

const response = await fetch(
	"https://api.openepi.io/weather/locationforecast?lat=52.520008&lon=13.404954"
)
const json = await response.json()

// Get the instant air temperature
const airTemperature =
	json.properties.timeseries[0].data.instant.details.air_temperature

console.log(`Air temperature: ${airTemperature}`)

from httpx import Client

with Client() as client:
    response = client.get(
        url="https://api.openepi.io/weather/locationforecast",
        params={"lat": 52.520008, "lon": 13.404954},
    )

    # Get the instant air temperature
    json = response.json()
    air_temperature = json["properties"]["timeseries"][0]["data"]["instant"]["details"][
        "air_temperature"
    ]

    print(f"Air temperature: {air_temperature}")
