JavaScript Example

const axios = require('axios');

const API_KEY = 'YOUR_ACCUWEATHER_API_KEY';
const BASE_URL = 'http://dataservice.accuweather.com';

// Get location key for a city
async function getLocationKey(city) {
  const response = await axios.get(
    `${BASE_URL}/locations/v1/cities/search`,
    { params: { apikey: API_KEY, q: city } }
  );
  return response.data[0]?.Key;
}

// Get current weather conditions
async function getCurrentConditions(locationKey) {
  const response = await axios.get(
    `${BASE_URL}/currentconditions/v1/${locationKey}`,
    { params: { apikey: API_KEY, details: true } }
  );
  return response.data[0];
}

// Get 5-day forecast
async function getFiveDayForecast(locationKey) {
  const response = await axios.get(
    `${BASE_URL}/forecasts/v1/daily/5day/${locationKey}`,
    { params: { apikey: API_KEY, metric: true } }
  );
  return response.data;
}

// Usage example
async function getWeather(city) {
  const locationKey = await getLocationKey(city);
  const current = await getCurrentConditions(locationKey);
  const forecast = await getFiveDayForecast(locationKey);
  
  console.log(`Current temperature in ${city}: ${current.Temperature.Metric.Value}°C`);
  console.log(`Conditions: ${current.WeatherText}`);
  console.log('5-Day Forecast:', forecast.DailyForecasts.map(d => 
    `${d.Date.split('T')[0]}: ${d.Temperature.Minimum.Value}°-${d.Temperature.Maximum.Value}°C`
  ));
}

getWeather('New York');

Python Example

import requests

API_KEY = 'YOUR_ACCUWEATHER_API_KEY'
BASE_URL = 'http://dataservice.accuweather.com'

def get_location_key(city):
    url = f'{BASE_URL}/locations/v1/cities/search'
    params = {'apikey': API_KEY, 'q': city}
    response = requests.get(url, params=params)
    data = response.json()
    return data[0]['Key'] if data else None

def get_current_conditions(location_key):
    url = f'{BASE_URL}/currentconditions/v1/{location_key}'
    params = {'apikey': API_KEY, 'details': 'true'}
    response = requests.get(url, params=params)
    return response.json()[0]

def get_five_day_forecast(location_key):
    url = f'{BASE_URL}/forecasts/v1/daily/5day/{location_key}'
    params = {'apikey': API_KEY, 'metric': 'true'}
    response = requests.get(url, params=params)
    return response.json()

# Usage
location_key = get_location_key('London')
current = get_current_conditions(location_key)
print(f"Temperature: {current['Temperature']['Metric']['Value']}°C")
print(f"Conditions: {current['WeatherText']}")
