</form>

<script>
document.getElementById('inquiry-form').addEventListener('submit', async (e) => {
  e.preventDefault();
  const form = e.target;
  const data = new FormData(form);

  const payload = {
    fields: {
      name: data.get('name'),
      email: data.get('email'),
      message: data.get('message')
    },
    honeypot: data.get('_gotcha') || ''
  };

  const res = await fetch('https://www.lugatu.com/api/v1/public/forms/YOUR_PUBLIC_FORM_ID/submissions', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json', 'Accept': 'application/json' },
    body: JSON.stringify(payload)
  });

  if (res.ok) {
    alert('Inquiry sent successfully!');
    form.reset();
  }
});
