Nanobanana Image Generator

A generative AI image creation tool powered by Google Gemini and monetized via Bitcoin Lightning payments using MoneyDevKit.

Features

• AI Image Generation: Create high-quality, artistic images based on a word and a feeling.
• Lightning Payments: Micro-transactions via Bitcoin Lightning Network to unlock generation.
• Serverless Architecture: Built with Next.js/Express logic adapted for Vercel Serverless Functions.
• Secure: API keys are kept server-side and never exposed to the client.

Deployment

This app is designed to be deployed on Vercel.
