How to Build an AI Product Listing Writer with AI Pass SDK

E-commerce sellers need listing copy constantly. In this tutorial, you'll build an AI tool that generates product titles, descriptions, and bullet points optimized for specific marketplaces. You earn 50% commission on every API call.

What You'll Build

A web app where users:

  1. Enter product details (name, features, audience)
  2. Select a marketplace (Amazon, Etsy, eBay)
  3. Get a complete listing with title, description, and bullet points

Step 1: Create Your AI Pass Account

  1. Go to aipass.one and sign up
  2. Verify your email (required for payouts)
  3. Open the Developer Dashboard

Step 2: Create an OAuth2 Client

  1. In the Developer Dashboard, go to OAuth2 Clients
  2. Click Create Client
  3. Copy your Client ID (looks like client_XXXX...)

Step 3: Build the App

  <script>
    AiPass.initialize({
      clientId: 'YOUR_CLIENT_ID',
      requireLogin: true,
      darkMode: true
    });

    async function generate() {
      const name = document.getElementById('name').value;
      const features = document.getElementById('features').value;
      const audience = document.getElementById('audience').value;
      const platform = document.getElementById('platform').value;
      const output = document.getElementById('output');
      output.style.display = 'block';
      output.textContent = 'Generating listing...';

      try {
        const r = await AiPass.generateCompletion({
          model: 'gpt-5-mini',
          temperature: 1,
          max_tokens: 16000,
          messages: [
            { role: 'system', content: `You are an expert e-commerce copywriter. Write a ${platform}-optimized product listing. Include: 1) SEO title 2) Product description (2-3 paragraphs) 3) 5 bullet points 4) Suggested search keywords. Format with clear headers.` },
            { role: 'user', content: `Product: ${name}\nFeatures: ${features}\nTarget audience: ${audience}\nPlatform: ${platform}` }
          ]
        });
        output.textContent = r.choices[0].message.content;
      } catch (e) {
        output.textContent = 'Error: ' + e.message;
      }
    }
  </script>
</body>
</html>

Step 4: Deploy

Option A: Self-host anywhere — GitHub Pages, Netlify, Vercel, your server. SDK handles auth and billing.

Option B: Publish on AI Pass — dedicated page with </> embed button.
