Nano Banana Pro via the Tokenator API

Q: What is the API ID of Nano Banana Pro?

nano-banana-pro — put this into the model field of your request.

Q: What does a generation request look like?

POST to /v1/images/generations with model , prompt and optionally n and size . The format matches the OpenAI Images API — only the base URL and the key change.

Q: How do I set the image size?

With the size field, for example 1024x1024 . The available set depends on the model; 2048x2048 is not supported everywhere, and even there the result sometimes comes back smaller — check the actual image.

Q: What comes back in the response?

A data array where each item holds a link to the finished image in the url field. Download the picture and store it on your side — the link is not meant for permanent hosting.

What the model is for

Nano Banana Pro is Google’s most advanced image-generation and editing model, built on Gemini 3 Pro. It extends the original Nano Banana with significantly improved multimodal reasoning, real-world grounding, and high-fidelity visual synthesis. The model generates context-rich graphics, from infographics and diagrams to cinematic composites, and can incorporate real-time information via Search grounding.
