Use Cases

Use this endpoint to populate a country/region selector in your UI:
async function loadRegions() {
  const regions = await fetch('/api/esim/regions?type=1', {
    headers: { 'X-API-Key': ' YOUR_API_KEY' }
  }).then(r => r.json());
  
  const selector = document.getElementById('country-select');
  regions.forEach(region => {
    const option = document.createElement('option');
    option.value = region.regionCode;
    option.text = region.regionName;
    selector.appendChild(option);
  });
}
Display which regions have available packages:
const regions = await getRegions();
const availableRegions = regions.filter(r => r.packageCount > 0);

console.log(`${availableRegions.length} regions have available packages`);
Create different sections for single-country and multi-country packages:
const countries = await fetch('/api/esim/regions?type=1', {
  headers: { 'X-API-Key': ' YOUR_API_KEY' }
}).then(r => r.json());

const multiCountry = await fetch('/api/esim/regions?type=2', {
  headers: { 'X-API-Key': ' YOUR_API_KEY' }
}).then(r => r.json());

displayCountries(countries);
displayRegionalPackages(multiCountry);
