}'How It Works
Get Started
Create an API key
In Dashboard → Developer API → Keys, create a revocable mi_ key and send it as a Bearer token.
Preview the cost
POST the same input to preview-credits and get the exact credit quote back. Previews never charge.
Generate and poll
POST to /models/{modelId}/generations, receive HTTP 202 with a generation ID, then poll the image status endpoint until terminal is true.
Nano Banana API pricing
Nano Banana, Nano Banana 2 and Nano Banana Pro per image
Live credit quotes for a single 1:1 text-to-image request at each resolution. Reference images do not change the model you call, only the request body.
| Model ID | Google model | Output | Reference images | Typical time | Credits per image |
|---|---|---|---|---|---|
| nano-banana | Gemini 2.5 Flash Image | 1K | Up to 3 | 10s | 1,955 |
| nano-banana-2 | Gemini 3.1 Flash Image | 1K | Up to 14 | 10s | 3,509 |
| nano-banana-2 | Gemini 3.1 Flash Image | 2K | Up to 14 | 10s | 5,264 |
| nano-banana-2 | Gemini 3.1 Flash Image | 4K | Up to 14 | 10s | 7,018 |
| nano-banana-pro | Gemini 3 Pro Image | 1K | Up to 14 | 12s | 7,018 |
| nano-banana-pro | Gemini 3 Pro Image | 2K | Up to 14 | 12s | 7,018 |
| nano-banana-pro | Gemini 3 Pro Image | 4K | Up to 14 | 12s | 12,031 |
Quotes are calculated from the live model pricing when this page is built. POST /models/{modelId}/preview-credits returns the exact cost of your own payload without charging.
Quickstart
Your first Nano Banana Pro request

What you get with the Nano Banana API
01
Three Google models, one contract
nano-banana, nano-banana-2 and nano-banana-pro share one request shape: a prompt plus optional imageUrls, aspectRatio and resolution.
02
Up to 4K output
Nano Banana 2 and Nano Banana Pro render at 1K, 2K or 4K, and Nano Banana 2 adds a 0.5K draft size for cheap iteration.
03
Reference-image editing
Send up to 14 reference image URLs to Nano Banana Pro or Nano Banana 2, or up to 3 to Nano Banana, to edit or keep a character consistent.
04
No separate API plan
REST, MCP and the dashboard draw from the same credit balance at the same model prices, with no monthly API fee.
05
Safe retries
Send an Idempotency-Key header and a retried request with the same body replays the original response instead of starting a second job.
06
Also in Claude and Cursor
The same models are available through the MCP connector, so an agent can generate Nano Banana images on your account.
Choosing a Nano Banana model
Which Nano Banana API should you call?
Start with Nano Banana 2 at 1K for drafts and volume, move hero images to Nano Banana Pro at 2K or 4K, and keep the original Nano Banana for cheap edits with up to three references. Switching is a one-word change to the model ID.
Nano Banana 2
Gemini 3.1 Flash Image for speed and cost, from 0.5K drafts up to 4K.
Nano Banana
Gemini 2.5 Flash Image for fast edits with up to three reference images.
