// Send OTP - Just 2 required fields
const { session_id } = await otpx.otp.send({
  channel: 'whatsapp',
  to: '+225xxxxxxxxx'
});

// Verify & get JWT
const { user, access_token } = await otpx.otp.verify({
  session_id,
  code: '123456',
  token_expiry: '7d'
});

// Social auth (no OAuth app setup needed)
const { url } = await otpx.social.authorize({
  provider: 'google',
  redirect_uri: 'https://myapp.com/callback'
});

The Problem

  • - Auth0 charges $35-$30,000+ monthly platform fees
  • - Clerk and Firebase have MAU limits that kill growth

  • - WhatsApp OTP is not available on competing platforms
