Punkt końcowy forecast udostępnia prognozę jakości powietrza w określonej lokalizacji na maksymalnie 96 godzin (4 dni). Każda prognoza zawiera godzinowe indeksy jakości powietrza oraz dodatkowe informacje:
Konkretna data i godzina lub okres prognozy
Kod języka przetłumaczonych pól
Lokalny lub niestandardowy indeks jakości powietrza (AQI)
Rekomendacje dotyczące zdrowia
Główne zanieczyszczenia
Stężenie zanieczyszczeń
Dodatkowe informacje o zanieczyszczeniach
Rozmiar strony odpowiedzi
Paleta kolorów
Narzędzie API Explorer umożliwia wysyłanie żądań w czasie rzeczywistym, dzięki czemu możesz zapoznać się z interfejsem API i jego opcjami:
W treści żądania umieść parametry. Treść żądania zawiera lokalizację, dla której chcesz uzyskać godzinową prognozę jakości powietrza, oraz różne opcje, które pozwalają określić, jakie dodatkowe informacje mają być uwzględnione w odpowiedzi.
Informacje o odpowiedziach prognozy
W treści odpowiedzi podawana jest data i godzina w UTC, dla których mają być wyświetlane informacje o prognozie jakości powietrza, indeksy jakości powietrza i dodatkowe informacje dostosowane do potrzeb użytkownika. Treść odpowiedzi zawiera też token umożliwiający pobranie następnej strony, jeśli informacje nie mieszczą się na stronie o rozmiarze określonym w żądaniu.
Przykład podstawowego żądania
Poniższy kod pokazuje, jak utworzyć żądanie prognozy. W tym przykładzie określasz lokalizację, datę i godzinę (od następnej godziny do 96 godzin), dla których mają być wyświetlane godzinowe prognozy jakości powietrza.

Przykład żądania z wieloma parametrami
Poniższy kod pokazuje, jak utworzyć treść żądania z wieloma parametrami. W tym przykładzie podajesz te informacje:
Lokalizacja
Przedział czasu, dla którego mają być wyświetlane informacje o prognozie jakości powietrza
Kod języka
Dodatkowe obliczenia (np. rekomendacje dotyczące zdrowia, stężenie dominującego zanieczyszczenia i dodatkowe informacje o zanieczyszczeniach)
Spowoduje to wyświetlenie następnej strony informacji o prognozie:
