🛠️ How it works

The system follows a modular Next.js App Router architecture designed for security and scalability:

• Server-Side API Routes: All detection calls go through /api/verify/* routes so provider credentials (Sapling, Sightengine) never reach the client.
• Content Provenance: Checks image metadata and C2PA signals to verify content origin.
• Rate Limiting: In-memory per-IP quota protection prevents abuse on detection endpoints.
• Stripe Integration: Webhook-driven subscription management for Pro tier upgrades.
