The Nano Banana Pro family on WaveSpeedAI ships 6 REST endpoints covering Image-To-Image, Text-To-Image workflows. Each variant carries its own pricing, parameter knobs, and example outputs — pick the one that matches your input modality and production constraints, or call several from the same API key to compose multi-step pipelines.
Run Nano Banana Pro through the same API key, billing account, and rate-limit envelope you use for the other 1,000+ AI models on WaveSpeedAI. No separate vendor setup, no per-provider SDKs, no per-vendor rate-limit envelopes — one integration covers everything from text-to-image and text-to-video through audio synthesis, 3D generation, upscaling, and editing.

How to use the Nano Banana Pro API
Four steps from signup to a finished generation. Full Python, Node.js, and cURL examples are in the API section below.
- 1
Get an API key
Sign up for a WaveSpeedAI account and copy your API key from the dashboard. New accounts come with free starter credits — enough to run the playground a few dozen times before billing kicks in.
- 2
Submit a prediction
POST your input as JSON to https://api.wavespeed.ai/api/v3/google/nano-banana-pro/text-to-image. The endpoint returns a prediction id immediately — generations are async so you don't hold an open connection during inference.
- 3
Poll for completion
GET https://api.wavespeed.ai/api/v3/predictions/{request_id}/result every 1-2 seconds. The response includes a status field; keep polling until it flips from "queued" or "processing" to "completed".
- 4
Read the output URL
Once status is "completed", read the URL from data.outputs[0]. The URL points to your generated media on the WaveSpeedAI CDN — image, video, audio, or 3D file depending on the Nano Banana Pro variant you called.
What you can build with Nano Banana Pro
Common workflows developers and creators use the Nano Banana Pro API for.
Marketing creatives with text
Nano Banana Pro renders accurate, properly-spelled text in 60+ languages — generate posters, ads, social cards, and event flyers without manual typography passes.
UI mockups & product visuals
Generate high-resolution dashboards, screen layouts, and app mockups with legible labels and consistent visual language.
Photo-realistic scenes
Lighting, materials, and physics rendered at a depth that matches Imagen 3 quality — drop straight into editorial or stock workflows.
Multi-subject composition
Edit-multi accepts up to 14 input images and maintains consistency across 5 subjects — useful for storyboards, product catalogs, character sheets.
Brand-safe outputs
Built-in safety classifiers + commercial-use license make it the safest pick for client-facing creative work.
Tips for prompting Nano Banana Pro
Practical advice for getting better outputs from Nano Banana Pro — drawn from the patterns that work across image models in production pipelines.
Describe lighting, composition, and style — not just subject
Move past 'a cat' to 'a tabby cat on a windowsill, soft afternoon light streaming in, shallow depth of field, cinematic 35mm composition'. Subject + scene + lighting + camera language is the prompt formula that pulls best from image-model training data.
Use style anchors instead of artist names
'In the style of editorial photography' or 'studio product shot, white seamless background' beats vague 'high quality, masterpiece' boilerplate AND avoids the legal / licensing concerns that come with naming living artists in commercial work.
Specify resolution and aspect ratio explicitly
Don't rely on defaults. Set the target aspect ratio (1:1, 4:3, 16:9) and resolution up front. Cropping or upscaling later loses fidelity that the model could have placed correctly in the first generation.
Iterate on a locked seed before re-rolling
Lock the seed, change one prompt element at a time. Much faster than re-rolling random seeds for every change — you isolate cause-and-effect on each prompt edit and reach the target image with fewer total generations.
Use the edit endpoint for refinements, not full re-generation
Generate the base image once, then use the model's edit / inpaint endpoint to refine specific elements — text, lighting, individual subjects. Edits preserve everything you liked about the base and cost less per iteration than full re-generations.
Nano Banana Pro API pricing
Pricing is per-output. The final charge scales with the parameters you set in each variant's playground (resolution, duration, output count, references).

When to pick Nano Banana Pro over similar models on WaveSpeedAI.
Nano Banana Pro vs GPT Image 2
GPT Image 2 is faster and cheaper per call. Nano Banana Pro produces sharper text and higher-resolution outputs (true 4K), and handles multi-subject editing better.
Nano Banana Pro vs Seedream 5
Seedream 5 Lite is the cost-optimized choice — half the price for general-purpose image gen. Nano Banana Pro wins on text rendering, multi-image editing, and 4K resolution.
