Common Use Cases

Create dependent dropdowns where states populate based on country selection.
const populateStatesDropdown = async (countryCode) => {
  const states = await getStatesByCountry(countryCode);
  const select = document.getElementById('state-select');
  
  // Clear existing options
  select.innerHTML = '<option value="">Select State...</option>';
  
  states.forEach(state => {
    const option = document.createElement('option');
    option.value = state.iso2;
    option.textContent = state.name;
    select.appendChild(option);
  });
};

// Listen for country changes
document.getElementById('country-select').addEventListener('change', (e) => {
  populateStatesDropdown(e.target.value);
});
Validate state codes against specific countries.
const validateStateForCountry = async (countryCode, stateCode) => {
  const states = await getStatesByCountry(countryCode);
  return states.some(state => state.iso2 === stateCode);
};
Cache states by country as they rarely change. Use this endpoint instead of filtering all states for better performance.
