Nano Banana Pro API: Empowering Developers with Cutting-Edge Image Generation with Gemini 3 Pro

4K High-Fidelity Rendering

One of the standout features of the Nano Banana Pro API is its ability to generate 4K high-fidelity images. This high-resolution capability ensures that every detail in the image is crisp and sharp, making it perfect for professional-grade visual assets or game assets. The ability to render images in 4K gives developers access to top-tier image quality without compromising on performance or speed.

Structured Typography

Typography plays a critical role in image generation, especially for projects involving text overlays or brand assets. Nano Banana Pro API provides structured typography support, ensuring that text is rendered with precise alignment, legibility, and style consistency. Developers can easily incorporate multi-language text into their images while maintaining clean and professional typography, making it ideal for international projects.

Multi-Object Scene Consistency

Creating consistent scenes with multiple objects can be a challenge, especially when working with dynamic content. Nano Banana Pro API ensures multi-object scene consistency, keeping the visual coherence of each element within the generated scene. This feature is essential for developers creating complex images with characters, environments, and objects that must maintain alignment, style, and accuracy throughout different frames or iterations.

Flexible Aspect Ratio Generation

Nano Banana Pro API supports flexible aspect ratio generation, making it easy to produce images that fit specific formats or media requirements. Whether you’re creating assets for websites, or apps, this feature lets developers define custom aspect ratios, ensuring that every image is perfectly sized for its intended use. This flexibility is key for delivering consistent visuals across various platforms.

How to Integrate the Nano Banana Pro API

Step 1: Obtain Your Nano Banana Pro API Key

Start by registering on Kie.ai and obtaining your Nano Banana Pro API key. This key is essential for making authenticated requests to the API. Simply visit the API Key Management Page, generate your key, and use it in the request headers: Authorization: Bearer YOUR_API_KEY. This step ensures secure access to Nano Banana Pro API.

Step 2: Create a Generation Task

To generate images, use the Nano Banana Pro API to create a task. Send a POST request to createTask with the appropriate parameters, including your API Key, model (nano-banana-pro), and input details such as prompt, aspect_ratio, and resolution. The API will return a taskId that you can use to track the progress of the task.

Step 3: Query the Task Status

Once the task is created, you can query its status by sending a GET request. The Nano Banana Pro API will return the task status, such as waiting, success, or failure. If you specify a callBackUrl, you’ll receive real-time notifications about the task's completion.

Step 4: Retrieve the Generated Results

After the task completes, check the task status. If the state is successful, extract the result from the resultJson field. This will include the generated image URLs, which you can use for your application. If the task fails, refer to the failCode and failMsg to diagnose the issue.
