Code Outline

Pseudocode / JavaScript 
// 1. Get air quality data
const aqiRes = await fetch(
  'https://api.airvisual.com/v2/nearest_city?key=YOUR_API_KEY'
);
const { data: aqiData } = await aqiRes.json();
const aqi = aqiData.current.pollution.aqius;

// 2. Get pollen data
const pollenRes = await fetch(
  'https://api.breezometer.com/pollen/v2/forecast/daily?lat=40.7&lon=-74.0&days=1&key=YOUR_API_KEY'
);
const pollenData = await pollenRes.json();
const pollenRisk = pollenData.data[0].types.grass.index.value;

// 3. Check thresholds
const isUnhealthy = aqi > 100 || pollenRisk > 3;

// 4. Send alert if needed
if (isUnhealthy) {
  await fetch('https://onesignal.com/api/v1/notifications', {
    method: 'POST',
    headers: { 'Authorization': 'Basic YOUR_KEY', 'Content-Type': 'application/json' },
    body: JSON.stringify({
      contents: { en: `Air Quality Alert: AQI ${aqi}, Pollen Risk: ${pollenRisk}/5` }
    })
  });
}
console.log(`AQI: ${aqi} | Pollen: ${pollenRisk}/5 | Alert: ${isUnhealthy}`);
