What You Will Build

A caption generator where users authenticate via AI Pass — no custom auth needed.

Step 1: Create an OAuth2 Client

Go to Developer Dashboard → OAuth2 Clients → Create → Copy Client ID.

Step 2: Add the SDK

<script src="https://aipass.one/aipass-sdk.js"></script>
<script>
  AiPass.initialize({ clientId: 'YOUR_CLIENT_ID', requireLogin: true });
</script>

Step 3: Generate Captions

const r = await AiPass.generateCompletion({
  model: 'gpt-5-mini',
  messages: [
    { role: 'system', content: 'You are a viral caption writer.' },
    { role: 'user', content: 'Generate 3 witty Instagram captions for: beach sunset' }
  ]
});
const captions = r.choices[0].message.content;
