O endpoint forecast
fornece até 96 horas (4 dias) de informações de previsão
da qualidade do ar por hora para um determinado local. Cada previsão inclui índices de qualidade do ar por hora e outras informações:
Período ou data e hora específicos para a previsão
Código do idioma para campos traduzidos
Índice de qualidade do ar (IQA) local ou personalizado
Recomendações de saúde
Poluentes dominantes
Concentração de poluentes
Mais informações sobre poluentes
Tamanho da página de resposta
Paleta de cores
Com o APIs Explorer, você pode fazer solicitações em tempo real para se familiarizar com
a API e as opções dela:
Inclua seus parâmetros no corpo da solicitação. O corpo da solicitação contém o local para o qual você quer receber informações de previsão horária da qualidade do ar e várias opções para controlar quais informações adicionais incluir na resposta.
Sobre as respostas de previsão
O corpo da resposta fornece a data e a hora em UTC para mostrar informações de previsão da qualidade do ar, índices de qualidade do ar e outras informações personalizadas. O corpo da resposta também inclui um token para recuperar a próxima página
se as informações não couberem no tamanho da página solicitada.
Exemplo de solicitação básica
O código a seguir mostra como criar uma solicitação de previsão. Neste exemplo, você especifica o local, a data e a hora (a partir da próxima hora até 96 horas) para mostrar as informações de previsão horária da qualidade do ar.
{"hourlyForecasts":[{"dateTime":"2024-02-09T08:00:00Z","indexes":[{"code":"uaqi","displayName":"Universal AQI","aqi":80,"aqiDisplay":"80","color":{"red":0.34509805,"green":0.74509805,"blue":0.20784314},"category":"Excellent air quality","dominantPollutant":"pm25"}]}],"regionCode":"us"}
Exemplo de solicitação com vários parâmetros
O código a seguir mostra como construir um corpo de solicitação com vários parâmetros. Neste exemplo, especifique o seguinte:
Local
Período em que as informações de previsão da qualidade do ar serão mostradas
Código do idioma
Cálculos extras (como recomendações de saúde, concentração do poluente dominante e informações adicionais sobre poluentes)
Isso retorna a próxima página de informações de previsão:

The response body also includes a token to retrieve the next page\nif the information does not fit within the requested page size.\n\nExample of basic request\n\nThe following code shows how to construct a forecast request. In this example,\nyou specify the location, date and time (beginning from the next hour up to 96\nhours) for which to show hourly air quality forecast information. \n\n```bash\ncurl -X POST -d '{\n \"location\": {\n \"latitude\": 37.4125333,\n \"longitude\": -122.0840937\n },\n \"dateTime\": \"2024-02-09T08:00:00Z\"\n}' \\\n-H \"Content-Type: application/json\" \\\n-H \"Accept-Language: *\" \\\n\"https://airquality.googleapis.com/v1/forecast:lookup?key=YOUR_API_KEY\"\n```\n\nThe call generates the following JSON response. \n\n```json\n{\n \"hourlyForecasts\": [\n {\n \"dateTime\": \"2024-02-09T08:00:00Z\",\n \"indexes\": [\n {\n \"code\": \"uaqi\",\n \"displayName\": \"Universal AQI\",\n \"aqi\": 80,\n \"aqiDisplay\": \"80\",\n \"color\": {\n \"red\": 0.34509805,\n \"green\": 0.74509805,\n \"blue\": 0.20784314\n },\n \"category\": \"Excellent air quality\",\n \"dominantPollutant\": \"pm25\"\n }\n ]\n }\n ],\n \"regionCode\": \"us\"\n}\n```\n| **Note:** If a `color` field value is `0`, that field is omitted from the response.\n\nExample of request with multiple parameters\n\nThe following code shows how to construct a request body with multiple\nparameters.
