If you’re a developer, marketer, or content creator looking to leverage the power of AI-driven image generation, the Nano Banana Pro API is a cutting-edge solution that enables text-to-image creation, image editing, and multimodal inputs.
In this guide, we’ll walk you through everything from setting up your development environment to advanced use cases, helping you integrate Nano Banana 2/Pro API into your applications efficiently.
The Google official Nano Banana Pro service is currently very congested — especially for free users, who are limited to only three generations at lower resolution. The good news is that GlobalGPT has fully integrated Nano Banana Pro, allowing you to use it here freely and without restrictions.

What Is Nano Banana Pro / Nano Banana 2 API? Overview for Developers
The Nano Banana ProAPI (also called Nano Banana 2 API or Gemini 3 Pro Image API) is Google’s developer-facing interface for programmatically accessing the advanced capabilities of Nano Banana Pro. It allows developers to generate high-quality images, edit visuals, and handle complex multi-image workflows directly from their applications. Through the API, you can send text prompts, upload reference images, and receive AI-generated outputs with precise control over style, composition, and text rendering.

Built on Gemini 3 Pro, the API brings multimodal AI, real-world knowledge grounding, and multilingual text support to developers, enabling automated creation of infographics, marketing assets, educational diagrams, and more. With SDKs, REST endpoints, and integration into platforms like Google AI Studio and Vertex AI, the Nano Banana Pro API makes it easy for developers and enterprises to embed state-of-the-art image generation and editing into apps, websites, or internal workflows.
