Complete guide to using Nano Banana Pro
Build robust imaging capabilities with Nano Banana Pro on APIPASS—cost-effective 2K/4K outputs, enhanced prompt comprehension, and reliable character consistency for production-ready applications.
Nano Banana Pro, newly released by Google DeepMind, represents the next step in high-fidelity image generation. Built on the upgraded Gemini 3.0 Pro Image architecture, it delivers sharper structural accuracy, improved character consistency, more precise text rendering, and cleaner material details. Google now offers these capabilities through the Google Nano Banana Pro API, enabling developers to programmatically generate images, control aspect ratios, handle multilingual text, and execute structured visual instructions. Developers can also experiment with the latest Gemini 3 Pro Image Preview variants when exploring early-iteration outputs. APIPASS provides an affordable, integration-friendly way to use the Nano Banana Pro API, featuring simplified pricing and a streamlined request workflow that fits directly into production systems, creative pipelines, or automated tools. This allows teams to leverage Google DeepMind’s advanced AI image generation capabilities without the complexity or higher operational costs often associated with enterprise cloud endpoints.
Generate studio-quality images with unprecedented detail and accuracy from text descriptions
Transform and enhance images with intelligent style transfer and precise control
Create intricate multi-element scenes with accurate spatial relationships and lighting
Produce ultra-sharp visuals directly at 1K, 2K, and 4K resolutions. The Nano Banana Pro API supports native high-definition generation, eliminating the need for external upscaling software. Your final images are guaranteed to be production-ready with professional-grade detail and peak sharpness.
Generate crisp, legible typography for posters, technical diagrams, and brand logos. Leveraging the Gemini 3 Pro Image API, this system supports accurate text generation across multiple languages. Use the Nano Banana Pro API to manage complex text instructions and localization requirements with ease.
Synthesize up to 8 input images into a single, cohesive output. By utilizing Nano Banana 2 blending logic, you can seamlessly merge style and content references. The API effectively harmonizes complex visual elements into one unified composition.
Exceptional ability to interpret complex, multi-layered prompts with nuanced artistic direction and technical specifications.
Leverage a deep understanding of the real world through specialized API endpoints. Generate scientifically accurate infographics or historically precise scenes. The Nano Banana Pro API processes sophisticated prompt logic to deliver fact-based visuals perfect for educational and professional content.
Maintain character and object identity across multiple frames with precision. Powered by Gemini-3-Pro-Image-Preview, the API ensures that facial features and specific details remain constant. Place your subjects in new environments or change their outfits while preserving their unique, recognizable identity.

All APIs require authentication via Bearer Token.
Authorization: Bearer
Create a new Google Nano Banana Pro image generation task.
The API accepts a JSON payload with the following structure:
1{
2 "model": "nano-banana-pro",
3 "callBackUrl": "string (optional)",
4 "channel": "auto",
5 "input": {
6 "prompt": "string",

12}modelRequiredstringThe model name to use for generation. Must be nano-banana-pro for this endpoint.
Available options:
"nano-banana-pro"
callBackUrlOptionalstringThe URL to receive generation task completion updates. APIPASS will POST task status, generated content URLs, and task information to this URL when generation completes. Your callback endpoint should accept POST requests with a JSON payload. If omitted, use the Query Task API to poll task status.
"https://your-domain.com/api/callback"
channelOptionalstringYou may specify the corresponding provider within APIPASS via the channel parameter; these providers handle the actual image and video generation tasks. APIPASS currently offers three provider options:
The default value for the channel parameter is auto. When enabled, APIPASS automatically allocates tasks across available providers based on real-time pricing and stability metrics to balance minimal cost and reliable performance. Retain the default auto value unless you have custom routing requirements.
Available options:
auto
The input object contains the following parameters:
input.promptRequiredstringA text description of the image you want to generate.
Maximum length: 10000 characters.
