Der Endpunkt forecast bietet stündliche Informationen zur Luftqualitätsvorhersage für einen bestimmten Standort für bis zu 96 Stunden (4 Tage). Jede Vorhersage enthält stündliche Luftqualitätsindizes sowie zusätzliche Informationen:
Bestimmte Uhrzeit und bestimmtes Datum oder Zeitraum für die Prognose
Sprachcode für übersetzte Felder
Lokaler oder benutzerdefinierter Luftqualitätsindex (LQI)
Gesundheitsempfehlungen
Dominante Schadstoffe
Schadstoffkonzentration
Weitere Informationen zu Schadstoffen

Farbvorlage
Mit dem APIs Explorer können Sie Liveanfragen stellen, um sich mit der API und den API-Optionen vertraut zu machen:
Sie können stündliche Informationen zur Luftqualitätsprognose über den Prognoseendpunkt anfordern, indem Sie eine HTTP-POST-Anfrage an folgende Adresse senden:
Fügen Sie Ihre Parameter in den Anfragetext ein. Der Anfragebody enthält den Ort, für den Sie stündliche Vorhersageinformationen zur Luftqualität abrufen möchten, sowie verschiedene Optionen, mit denen Sie steuern können, welche zusätzlichen Informationen in die Antwort aufgenommen werden sollen.
Prognoseantworten
Der Antworttext enthält das UTC-Datum und die UTC-Uhrzeit, für die Informationen zur Vorhersage der Luftqualität, Luftqualitätsindizes und zusätzliche benutzerdefinierte Informationen angezeigt werden sollen. Der Antworttext enthält auch ein Token zum Abrufen der nächsten Seite, wenn die Informationen nicht in die angeforderte Seitengröße passen.
Beispiel für eine einfache Anfrage
Der folgende Code zeigt, wie eine Prognoseanfrage erstellt wird. In diesem Beispiel geben Sie den Ort, das Datum und die Uhrzeit (beginnend mit der nächsten Stunde bis zu 96 Stunden) an, für die stündliche Informationen zur Luftqualität angezeigt werden sollen.
