NanoBanana Image Generation

Generate and edit AI images through AceDataCloud's NanoBanana (Gemini-based) API.

Setup: See authentication for token setup.

Quick Start

curl -X POST https://api.acedata.cloud/nano-banana/images \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "generate", "prompt": "a watercolor painting of a French countryside village", "model": "nano-banana"}'

Async: See async task polling. Poll via POST /nano-banana/tasks with {"id": "..."}.

Models

Model	Best For
nano-banana	Standard image generation (default)
nano-banana-2	Improved quality, second generation
nano-banana-pro	Highest quality, most detailed output
nano-banana:official	Official channel variant of nano-banana
nano-banana-2:official	Official channel variant of nano-banana-2
nano-banana-pro:official	Official channel variant of nano-banana-pro

Workflows

1. Text-to-Image

POST /nano-banana/images
{
  "action": "generate",
  "prompt": "a photorealistic macro shot of morning dew on a spider web",
  "model": "nano-banana-pro",
  "aspect_ratio": "16:9",
  "resolution": "2K"
}

2. Image Editing

Edit existing images using natural language instructions — no mask needed. Pass source images via image_urls.

POST /nano-banana/images
{
  "action": "edit",
  "prompt": "change the background to a starry night sky",
  "image_urls": ["https://example.com/photo.jpg"],
  "model": "nano-banana"
}

Parameters

Parameter	Values	Description
action	"generate", "edit"	Operation mode
model	"nano-banana", "nano-banana-2", "nano-banana-pro", "nano-banana:official", "nano-banana-2:official", "nano-banana-pro:official"	Model to use
prompt	string	Image description or editing instruction
image_urls	array of strings	Source image URLs (required for edit action)
aspect_ratio	"1:1", "3:2", "2:3", "16:9", "9:16", "4:3", "3:4"	Output aspect ratio
resolution	"1K", "2K", "4K"	Output resolution (1K=1024px, 2K=2048px, 4K=4096px)
callback_url	string	Async callback URL; returns a task ID immediately

Gotchas

• Editing does NOT require a mask — just describe the change in natural language
• Editing uses the same /nano-banana/images endpoint with action: "edit" and image_urls array (not a separate /edit path)
• nano-banana-2 is the second-generation model; nano-banana-pro offers the highest quality
• :official variants (e.g., nano-banana:official) route through the official channel
• Task polling uses id (not task_id) in the /nano-banana/tasks request body
• Aspect ratio uses colon notation (e.g., "16:9") not pixel dimensions
• The Gemini-based model excels at understanding complex, conversational editing instructions
