Can I build my own Stripe with AI?

**Do not use this prompt to replace Stripe.** Use it only if you want a demo checkout flow that redirects to a real payment provider.

Build a simple product checkout demo that integrates with Stripe Checkout (hosted), not a custom payment processor.

**Objective:** Let a user click "Buy" and complete payment through Stripe's hosted checkout page.

**Target user:** A founder learning how payment integration works, using Stripe's test mode.

**Core functionality:**
- Product page with name, price, and description
- "Buy now" button that creates a Stripe Checkout Session
- Redirect to Stripe-hosted checkout
- Success and cancel return pages
- Webhook endpoint (or polling) to confirm payment in test mode

**Pages/screens:**
- Product / pricing page
- Success page
- Cancel page

**User flows:**
1. User clicks Buy
2. Backend creates Checkout Session via Stripe API
3. User pays on Stripe's hosted page
4. User returns to success URL; app shows confirmation

**UI direction:** Clean, trustworthy, minimal, no fake "card form" that touches PAN data.

**Data model:**
- Product: { name, price, stripePriceId }
- Order: { stripeSessionId, status, email, amount }

**Authentication:** None for public checkout; protect webhook secret server-side.

**APIs/integrations:** Stripe Checkout and webhooks only. No custom card storage.

**Explicit exclusions:** No custom payment gateway, no stored card numbers, no subscription engine, no marketplace payouts, no fraud scoring.
