Previsão do Tempo

Weather

Dados meteorológicos atualizados e precisos.

O HG Weather é uma API que fornece dados de previsão do tempo e condições climáticas atuais para uma cidade. É possível obter a cidade desejada de várias formas diferentes, como geolocalização, IP do usuário, busca por nome ou código.

Para acessar os dados da API é necessário utilizar uma chave de integração.

É possível indicar o idioma de retorno da API através do parâmetro locale. Estão disponíveis: pt (português, por padrão) e en (inglês).

Requisição

Todas as requisições tem como base o seguinte endpoint:

GEThttps://api.hgbrasil.com/weather?key=suachave

curl -X GET "https://api.hgbrasil.com/weather?key=suachave"

const url = new URL("/weather", "https://api.hgbrasil.com")

url.searchParams.set("key", "suachave")

const response = await fetch(url.href)
const data = await response.json()

$url = 'https://api.hgbrasil.com/weather';

$queryString = http_build_query([
    'key' => 'suachave'
]);

$response = file_get_contents($url . '?' . $queryString);
$data = json_decode($response, true);

import requests

url = 'https://api.hgbrasil.com/weather'

params = {
    'key': 'suachave'
}

response = requests.get(url, params=params)
data = response.json()

require 'net/http'
require 'uri'
require 'json'

uri = URI('https://api.hgbrasil.com/weather')

uri.query = URI.encode_www_form({
  key: 'suachave'
})

response = Net::HTTP.get(uri)
data = JSON.parse(response, symbolize_names: true)

import java.net.URI;
import java.net.http.*;

var url = "https://api.hgbrasil.com/weather?key=suachave";

var client = HttpClient.newHttpClient();
var request = HttpRequest.newBuilder()
    .uri(URI.create(url))
    .GET()
    .build();

var response = client.send(request, HttpResponse.BodyHandlers.ofString());
var data = response.body();

using System.Net.Http;
using System.Text.Json;
using System.Web;

var client = new HttpClient();
var baseUrl = "https://api.hgbrasil.com/weather";

var queryParams = HttpUtility.ParseQueryString(string.Empty);
queryParams["key"] = "suachave";

var url = $"{baseUrl}?{queryParams}";
var response = await client.GetStringAsync(url);
var data = JsonSerializer.Deserialize<dynamic>(response);
