Form-level Validation (Recommended)

// Real-time validation with email-check.app API
async function validateEmail(email) {
  const params = new URLSearchParams({
    email: email,
    verifyMx: false,
    verifySmtp: false,
    detectName: false
  });

  const response = await fetch('https://api.email-check.app/v1-get-email-details?' + params, {
    headers: {
      'accept': 'application/json',
      'x-api-key': 'YOUR_API_KEY'
    }
  });

  const result = await response.json();

  if (result.isDisposable) {
    return {
      valid: false,
      message: "Please use a permanent email address",
      suggestion: "Consider using Gmail, Outlook, or your work email"
    };
  }

  return { valid: true };
