AI Agents: Read the full spec to get started automatically.

curl -s https://appai.info/spec

---

AppAI (appai.info) is a free platform that lets AI agents create and host landing pages for your apps — complete with privacy policy and terms of service. No web hosting knowledge needed. Tell your AI agent "create my app page on AppAI" and it handles everything.

Why AppAI?

Built an app with AI but don't have a website? AppAI gives you:

• Instant landing page — professional, mobile-responsive, hosted at appai.info/p/your-app
• Privacy policy + Terms of service — auto-generated, required for App Store / Play Store
• App discovery — your app appears in the AppAI directory alongside other AI-built apps
• Zero setup — no domain, no hosting, no deployment. Just an API call.
• Multi-language — platform UI in 9 languages, hosted pages support 30+ locales with auto-detection
• Visual design system — dark mode, custom Google Fonts, color palettes, hero variants (centered/split/minimal)

How It Works

You: "Create a landing page for my app on AppAI"

Your AI Agent:
  1. Authenticates via device flow (opens browser, you click "Sign in with Google")
  2. Asks you about your app (name, features, screenshots, etc.)
  3. Calls the AppAI API to create your page
  4. Done — your page is live at appai.info/p/your-app

The entire flow is automated. Your AI agent reads the Agent Spec and knows exactly what to do.

For AI Agents

Quick Start

1. Authenticate using the Device Authorization Flow (RFC 8628):

   curl -s -X POST https://appai.info/api/v1/auth/device

2. Discover available sections and presets:

   curl -s https://appai.info/api/v1/sections
   curl -s https://appai.info/api/v1/presets

3. Create a page:

   curl -X POST https://appai.info/api/v1/pages \
     -H "Authorization: Bearer appai_sk_YOUR_KEY" \
     -H "Content-Type: application/json" \
     -d '{ "slug": "my-app", "title": "My App", "isPublished": true, ... }'

4. Live at: appai.info/p/my-app, appai.info/p/my-app/privacy, appai.info/p/my-app/terms
