Nano Banana 2 Edit API
Integrate reference-guided image editing through GoEnhance. Send one to nine source images with a prompt, choose an output size and ratio, then resolve the result by polling or HTTPS callback. GoEnhance provides independent API access and is not Google’s official Gemini API.

Reference-Guided Editing for Developer Workflows
Prompt Plus Up to Nine Images
Provide a 1–2000 character prompt and one to nine accessible image URLs in image_list. Select a supported ratio and 0.5K, 1K, 2K, or 4K output size.
Async Results for Production Apps
A successful submission returns an img_uuid. Persist it, poll /api/v1/jobs/detail, or receive task-status events at a public HTTPS callback URL.
Validate the live request contract before submitting an edit.

Integrate Nano Banana 2 Edit in Three Steps
1
1. Prepare the Edit
Host one to nine source images at accessible URLs, write a precise prompt, choose the ratio and image size, and optionally configure a callback.
2
2. Submit and Store the ID
POST the JSON payload with authorization, validate the response, and persist the returned
img_uuid with your application job. 3
3. Resolve the Result
Poll the task-detail endpoint or validate callback events until the task succeeds or fails, then store the output or surface the failure safely.
