The API offers high-precision forecasts based on weather data processed by the Yandex.Weather service. This API is capable of delivering real-time weather updates, detailed forecasts for a specified period, and historical weather data. It uses current weather measurements from multiple sources, satellite images, radar data, and the measurements taken at weather observation stations. For more detailed information about the API’s methods and response format, it refers to the official documentation at "https://yandex.com/dev/weather/".

Leveraging weather forecasts at hyper-local level give businesses opportunity to tailor their goods and services according to the potential requirements in specific locations.

Here is a simple JavaScript-based code example demonstrating how to call the Yandex Weather API:

const axios = require('axios');

let APIKey = '<YOUR_API_KEY>'; 
let location = '<YOUR_LOCATION>'; 

axios.get(`https://api.weather.yandex.com/v1/forecast?lat=${location}&lon=${location}`, {
  headers: {
    'X-Yandex-API-Key': APIKey
  }
}).then((response) => {
  console.log(response.data);
}).catch((error) => {
  console.error(`Could not retrieve weather data: ${error}`);
});

In this example, replace <YOUR_API_KEY> and <YOUR_LOCATION> with your Yandex Weather API key and required location respectively.
