Is this the official Google Nano Banana API?

No. The Nano Banana API on this site is the Nano AI image API — an independent service that is not affiliated with Google.

Where do I get an API key?

Sign in and open the API keys page in your dashboard to create a key. Send it on every request as "Authorization: Bearer YOUR_API_KEY".

Is the API synchronous?

No. Generate and edit calls return a task_id immediately. Poll /api/status until the task finishes and returns the image URLs.

Which model should I use?

nano2 is the recommended default. Keep nano for existing integrations and choose nano2pro when you want the highest quality output.

Can I edit images through the API?

Yes — POST /api/edit accepts image URLs plus a prompt, and uses the same model field and task flow as generation.

How much does the API cost?

API calls consume account credits. New accounts receive free credits after sign-in; see the pricing page for packages.

Developer API

Nano Banana API: Nano AI Image Generation API

The Nano Banana API is the Nano AI image API: generate and edit images with nano, nano2 or nano2pro through one authenticated surface — submit a task, poll for the result.

Quickstart

Create a key on the API keys page, then send a POST to /api/generate with your prompt and model. The response returns a task_id — poll /api/status until the task finishes.

bash

curl -X POST "https://nanobnana.com/api/generate" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A professional product photo of a modern wristwatch on a clean white background",
    "model": "nano2"
  }'

Endpoints

One API surface covers every model — pick nano, nano2 or nano2pro with the model field instead of switching endpoints.

POST/api/generate

Text to image

Create a generation task from a text prompt for nano, nano2 or nano2pro.

POST/api/edit

Image editing

Create an editing task with image URLs and a prompt on the same task flow.

GET/api/status

Task status

Poll any task with task_id and retrieve the generated image URLs when it succeeds.

Models

Set the model field on every request. nano2 is the recommended default for new integrations.

Model	Model name	Use case
`nano`	Original Nano AI Fast	Backward-compatible default for existing integrations.
`nano2`	Nano AI 2	Recommended default for new image generation integrations.
`nano2pro`	Nano AI 2 Pro	Higher quality generation and editing workflows.

Integrate in three steps

The API is asynchronous: every generate or edit call returns a task_id that you poll until the image is ready.

Create an API key

Submit a task

POST to /api/generate or /api/edit with your prompt and model; the response contains a task_id.

Poll for the result

Call GET /api/status?task_id=… until the task succeeds and the response carries the image URLs.
