Generate product creative images with Google Nano-Banana model via Defapi

Overview

This workflow utilizes the Defapi API with Google's Nano-Banana model to generate AI-powered product creative images from text prompts and product images. Users can interact through a simple form, providing a text prompt describing the desired creative scene, a product image URL, and their API key. The system automatically submits the request to the Defapi API, monitors the generation status in real time, and retrieves the final creative image output. This solution is ideal for marketers, product designers, e-commerce businesses, and content creators who want to quickly generate compelling product advertisements and creative visuals with minimal setup.
