# 1. Send OTP Verification Code
curl -X POST https://noreply.intent.ngo/api/v1/emails/otp \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "user@example.com",
    "code": "849201",
    "app_name": "My App",
    "purpose": "Login Verification",
    "expires_in_minutes": 10
  }'

# 2. Send Custom HTML Transactional Email
curl -X POST https://noreply.intent.ngo/api/v1/emails \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "My App ",
    "to": "user@example.com",
    "subject": "Welcome to our platform!",
    "html": "Welcome aboard!
Your workspace is active."
  }'

// Send OTP using standard fetch in Node.js 18+
const res = await fetch('https://noreply.intent.ngo/api/v1/emails/otp', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    to: 'user@example.com',
    code: '849201',
    app_name: 'My Service',
    purpose: 'Password Reset',
    expires_in_minutes: 10
  })
});
const data = await res.json();
console.log(data);

import requests
