Nano Banana 2 Lite API
Generate 1K images from text with the Nano Banana 2 Lite model through GoEnhance's independent API. Submit a prompt, receive an asynchronous image task ID, then poll or use a callback. GoEnhance is not Google, and this endpoint is not Google's official Gemini API.
Create an API Key
A focused 1K text-to-image API
Prompt-driven image generation
Send the exact model ID nano-banana-2-lite with a 1–2000 character prompt. Select a supported aspect ratio or leave ratio as auto.
Asynchronous delivery
A successful submission returns img_uuid. Poll the job-detail endpoint or provide a public HTTPS callback URL to receive processing, success, and failure updates.
Validate these fields before submission to keep integrations predictable.
Nano Banana 2 Lite API parameters
Model
Required. Set <code>model</code> to <code>nano-banana-2-lite</code>.
Prompt
Required text description from 1 to 2000 characters.
Aspect ratio
Optional <code>ratio</code>; defaults to <code>auto</code>. Supported values include 1:1, 16:9, 9:16, 4:3, 3:4, 2:3, 3:2, 4:5, 5:4, 1:4, 4:1, 1:8, 8:1, and 21:9.
Thinking level
Optional reasoning depth with <code>High</code> or <code>Minimal</code>.
Callback URL
Optional <code>custom_callback_url</code> must be a publicly accessible HTTPS URL.
Authorization
Authenticate requests with the <code>Authorization</code> header and send JSON to the generations endpoint.
Use the documented per-image rate and asynchronous response contract when estimating usage.
Nano Banana 2 Lite API pricing and task behavior
2 tokens per image
The documented Nano Banana 2 Lite API price is 2 tokens, equal to $0.04, for each generated image.
1K output
Nano Banana 2 Lite generates 1K output only; this route does not expose 2K or 4K size controls.
Task-based results
Submission returns <code>img_uuid</code>, not the final image. Retrieve the terminal result by polling or callback.
Integrate in three steps
1
1. Create the request
POST JSON to
https://api.goenhance.ai/api/v1/images/generations with your authorization header, model ID, prompt, and optional ratio, thinking level, or callback URL. 2
2. Store img_uuid
Read
data.img_uuid from a successful response and associate it with your own request record. 3
3. Poll or receive callbacks
Poll
GET /api/v1/jobs/detail or process callback events. If a callback response is not HTTP 200, GoEnhance documents up to three retries with a three-second timeout per attempt.A low-complexity text-to-image route can support repeatable creative production while your application controls prompts, review, and delivery.
