Tech Stack

• Next.js 15 (App Router) + TypeScript
• Tailwind CSS v4
• API key stored in localStorage
• Server-side proxy routes (no CORS issues)

Architecture

Browser → /api/generate (POST) → deAPI /txt2music
Browser → /api/status/:id (GET) → deAPI /request-status/:id

API key is sent via x-api-key header to the proxy routes, which forward it as Authorization: Bearer to deAPI.
