About Nano Banana 2

Nano Banana 2 by Google is available on API Many from $0.019 / image, and you call it with the same API key you use for every other model.

Send a prompt — and reference images when the model supports them — to /v1/images/generations. The job runs asynchronously and the finished images stay downloadable for 30 days.

You pay only for successful results: failed or rejected requests are refunded automatically, and every call is recorded in your console with its exact cost.
