NanoBanana CLI

A command-line tool for AI image generation and editing using NanoBanana (Gemini-powered) through the AceDataCloud API.

Generate and edit AI images directly from your terminal — no MCP client required.

Features

• Image Generation — Generate images from text prompts with multiple models
• Image Editing — Edit, combine, and transform images with AI
• Multiple Models — nano-banana (fast), nano-banana-2 (improved), nano-banana-pro (best, 4K)
• Flexible Output — Aspect ratios (1:1, 16:9, 9:16, etc.) and resolutions (1K/2K/4K)
• Task Management — Query tasks, batch query, wait with polling
• Rich Output — Beautiful terminal tables and panels via Rich
• JSON Mode — Machine-readable output with --json for piping

Quick Start

1. Get API Token

Get your API token from AceDataCloud Platform:

1. Sign up or log in
2. Navigate to the NanoBanana API page
3. Click "Acquire" to get your token

2. Install

# Install with pip
pip install nano-banana-pro-cli

# Or with uv (recommended)
uv pip install nano-banana-pro-cli

# Or from source
git clone https://github.com/AceDataCloud/NanoBananaCli.git
cd NanoBananaCli
pip install -e .

3. Configure

# Set your API token
export ACEDATACLOUD_API_TOKEN=your_token_here

# Or use .env file
cp .env.example .env
# Edit .env with your token

4. Use

# Generate an image from a prompt
nano-banana-pro generate "A cat sitting on a windowsill at sunset, warm lighting"

# Generate with specific model and aspect ratio
nano-banana-pro generate "Product photo of a watch" -m nano-banana-pro -a 16:9 -r 4K

# Edit an image
nano-banana-pro edit "Make it look like an oil painting" -i https://example.com/photo.jpg

# Virtual try-on (combine person + clothing)
nano-banana-pro edit "Let this person wear this T-shirt" -i person.jpg -i shirt.jpg

# Check task status
nano-banana-pro task <task-id>

# Wait for completion with polling
nano-banana-pro wait <task-id> --interval 5

# List available models
nano-banana-pro models

Utilities

Global Options

--token TEXT    API token (or set ACEDATACLOUD_API_TOKEN env var)
--version       Show version
--help          Show help message

Most commands support:

--json          Output raw JSON (for piping/scripting)
--model TEXT    NanoBanana model version (default: nano-banana)

Scripting & Piping

The --json flag outputs machine-readable JSON suitable for piping:

# Generate and extract task ID
TASK_ID=$(nano-banana-pro generate "a red circle" --json | jq -r '.task_id')

# Wait for completion and get image URL
nano-banana-pro wait $TASK_ID --json | jq -r '.data[0].image_url'

# Batch generate from a file of prompts
while IFS= read -r prompt; do
  nano-banana-pro generate "$prompt" --json >> results.jsonl
done < prompts.txt
