Nano Banana Pro OpenRouter

An image generation skill that leverages OpenRouter's API to access Nano Banana Pro and other image generation models, enabling AI-powered image creation, editing, and transformation from text prompts.

What Is This?

Overview

This skill integrates with OpenRouter's unified API to access image generation models including Nano Banana Pro. It handles prompt formatting, API configuration, model selection, and response processing to generate images from text descriptions directly within your AI assistant workflow.

Who Should Use This

Perfect for developers integrating image generation into applications, content creators needing AI-generated visuals, designers creating concept art and mockups, and teams automating visual content production.

Why Use It?

Problems It Solves

Accessing multiple image generation models requires managing different APIs, authentication methods, and prompt formats. OpenRouter provides a unified interface, but configuring it correctly with proper parameters and handling responses requires specific knowledge this skill provides.

Core Highlights

• Unified API Access - Single endpoint for multiple image generation models
• Prompt Optimization - Guidance for effective image generation prompts
• Model Selection - Choose the right model for your use case and budget
• Response Handling - Parse and save generated images properly
• Cost Management - Track token usage and optimize for cost efficiency

How to Use It?

Basic Usage

Ask Claude to generate images via OpenRouter, and this skill handles API configuration.

Scenario 1: Basic Image Generation

Ask Claude: "Generate an image of a mountain landscape at sunset"

Claude will construct the API call:

curl https://openrouter.ai/api/v1/images/generations   -H "Authorization: Bearer $OPENROUTER_API_KEY"   -H "Content-Type: application/json"   -d '{
    "model": "nano-banana-pro",
    "prompt": "A majestic mountain landscape at sunset, golden light casting long shadows across alpine meadows, snow-capped peaks reflecting warm orange and purple hues, photorealistic style",
    "n": 1,
    "size": "1024x1024",
    "quality": "standard"
  }'

Scenario 2: Programmatic Integration

Tell Claude: "Integrate image generation into my Node.js app"

Claude will provide:

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://openrouter.ai/api/v1",
  apiKey: process.env.OPENROUTER_API_KEY,
});

async function generateImage(prompt, options = {}) {
  const response = await client.images.generate({
    model: options.model || "nano-banana-pro",
    prompt,
    n: options.count || 1,
    size: options.size || "1024x1024",
  });
  return response.data.map(img => img.url);
}

const images = await generateImage(
  "Modern minimalist logo for a tech startup, clean lines, blue gradient"
);
console.log("Generated:", images[0]);

Real-World Examples

Marketing Asset Pipeline

A marketing team automated hero image generation for blog posts. Each article's metadata fed into prompt templates, producing consistent brand-aligned visuals without manual design work.

Rapid Prototyping

A product designer used text-to-image generation to create 20 UI concept variations in an hour. Iterating on prompts was faster than sketching, enabling broader design exploration.

Advanced Tips

Prompt Engineering

Structure prompts with subject, style, lighting, and composition details. Be specific about artistic style (photorealistic, watercolor, isometric) for consistent results.

Model Comparison

Test the same prompt across different models available on OpenRouter to compare quality, speed, and cost. Different models excel at different styles and subjects.

When to Use It?

Use Cases

• Content Creation - Generate images for blog posts, social media, and marketing
• Concept Art - Create visual concepts for products and features
• Prototyping - Produce UI mockups and design explorations quickly
• App Integration - Add image generation features to applications
• Batch Generation - Create multiple image variations programmatically

Important Notes

Requirements

• OpenRouter API key with image generation access
• Sufficient API credits for image generation requests
• Node.js 18+ or Python 3.9+ for SDK integration
• Network access to OpenRouter API endpoints

Usage Recommendations

Do:

• Write detailed prompts - Specific descriptions produce better results
• Specify art style - Include style keywords for consistent output
• Set appropriate sizes - Match output resolution to your use case
• Cache generated images - Save results to avoid regenerating identical content

Don't:

• Don't use vague prompts - Generic descriptions produce inconsistent results
• Don't ignore content policies - Follow OpenRouter's acceptable use guidelines
• Don't skip error handling - API calls can fail or timeout

Limitations

• Image quality varies by model and prompt specificity
• Generation times depend on model complexity and server load
• API rate limits apply to concurrent generation requests
• Generated images may require manual refinement for production use
