Nano Banana API Complete Guide
Learn how to integrate the Nano Banana API, explore its capabilities, and start generating professional images for your applications.
What is the Nano Banana API?
The Nano Banana API is built on Google's Gemini 2.5 Flash Image Preview model. It provides developers with a simple REST endpoint for generating and editing images using natural language prompts — no ML expertise required.
The Nano Banana API supports two modes: text-to-image for creating visuals from scratch, and image-to-image for editing existing photos. In image-to-image mode, you can supply up to 5 reference images to combine styles, swap objects, or transform scenes.
With average generation times of 10–15 seconds, 11 aspect ratio options, and pricing at $0.03 per image, the Nano Banana API delivers production-ready results at a fraction of the cost of competing services.
