Quick Start#

from dlubal.api.geo_zone_tool import GeoZoneTool, Language, LoadZoneType

gzt = GeoZoneTool(token="YOUR_TOKEN")

result = gzt.get_load_zone_characteristics(
    address="Munich, Germany",
    load_zone_type=LoadZoneType.SNOW,
    standard="EN 1991-1-3",
    annex="Germany",
    layer_id=1,
    language=Language.EN,
)
print(result.code)

using Dlubal.API.GeoZoneTool;

var gzt = new GeoZoneToolClient("YOUR_TOKEN");

var result = await gzt.GetLoadZoneCharacteristicsAsync(
    address: "Munich, Germany",
    loadZoneType: LoadZoneType.Snow,
    standard: "EN 1991-1-3",
    annex: "Germany",
    layerId: 1,
    language: Language.En
);
Console.WriteLine(result.Code);

Authentication#

Most queries require a Bearer token passed in the Authorization header:

Authorization: Bearer YOUR_TOKEN

Queries marked Public do not require authentication. All others consume one API credit per request.
