Text that renders correctly is where Nano Banana Pro stands apart. Headlines, labels, and captions stay legible inside the image, so posters, packaging, and UI mockups arrive ready to use.
With Nano Banana Pro on Pollo API, developers add text-to-image, image editing, and multi-image composition to their apps, generating at 1K, 2K, or 4K across ten aspect ratios per request.
Key Features of Nano Banana Pro API
Reliable In-Image Typography
Words render as intended, with correct spelling and clean letterforms, making the model dependable for titles, product labels, signage, and layouts where readable text is the point.
Native 2K With 4K Detail
Images generate at native 2K and scale up to 4K, holding fine texture, edges, and small elements so results stay crisp when printed or displayed large.
Multi-Image Composition
Feed several reference images and the model blends subjects, styles, or products into one coherent frame, useful for combining assets that never existed in the same shot.
Prompt Understanding
Longer, detailed descriptions are followed closely, so specific arrangements, materials, and relationships between elements translate into the image without heavy rerolling.
Lighting And Composition Control
Direction of light, framing, and spatial layout respond to instructions, letting you place subjects, set mood, and control depth rather than accepting a random composition.
Precise Image Editing
Start from an existing image and adjust content, style, or elements while keeping the rest intact, supporting iterative refinement instead of regenerating from scratch.
Use Cases of Nano Banana Pro API
Poster And Ad Layouts: Generate promotional images with a headline, subtext, and call-to-action rendered legibly, cutting the manual text-overlay step for marketing tools.
Product Packaging Mockups: Place brand names, ingredients, and label copy onto boxes or bottles with readable typography for packaging and ecommerce previews.
Multi-Reference Compositing: Merge a model, a product, and a backdrop from separate images into a single staged scene for catalog and campaign apps.
Infographics And Diagrams: Produce charts, labeled figures, and data cards where the text needs to be accurate and clearly positioned.
Menu And Recipe Cards: Create food imagery with dish names, prices, and descriptions typeset directly in the frame for restaurant and content platforms.
Localized Creative Variants: Swap headline copy across languages while keeping layout and style, generating regional versions from one design template.
Editorial And Thumbnail Art: Build cover images and thumbnails at high resolution with titles baked in, ready for blogs, video platforms, and social feeds.
Design Iteration Tools: Edit an approved image to try new colors, backgrounds, or elements without losing the parts that already work.
How to Use Nano Banana Pro API
Get an API Key: Create a Pollo API account and generate your API key from the developer dashboard.
Choose the Model: Send requests to the Nano Banana Pro endpoint at /generation/google/nano-banana-pro/image.
Add Your Inputs: Provide a prompt and aspectRatio for text-to-image, or add imageUrl or an images array for editing and multi-image composition, then set resolution to 1K, 2K, or 4K.
Generate and Retrieve: Submit the task, poll the returned task status, and download the finished image once processing succeeds.
Prompting Best Practices for Nano Banana Pro API
Write prompts like a design brief. State the subject, the exact text to display, the layout, the lighting, and the style, so the model can place readable copy inside a controlled composition.
A Simple Prompt Formula
Subject and scene + exact text in quotes + layout and placement + lighting and mood + style and aspect ratio
What You Should Notice
Quote The Exact Text: Put wording you want rendered in quotation marks so spelling and phrasing come through accurately.
Describe The Layout: Say where the title, subtext, or subject sits, since placement instructions shape the composition.
Set The Lighting: Name the light source and direction to control mood, shadows, and how materials read.
Match Resolution To Output: Choose 2K or 4K for print and large displays, 1K for fast drafts and previews.
Guide Multi-Image Blends: When combining references, explain how each element should relate so the blend stays coherent.
Pick The Aspect Ratio: Select the ratio up front to fit the target format, from square social posts to wide 21:9 banners.
