Generate Character-Consistent Images with KIE.AI Nano Banana API

Overview

Generate high-quality, character-consistent AI images using KIE.AI's Nano Banana API through an intuitive form interface. This n8n workflow supports both text-to-image and image-to-image generation modes, delivering professional results at 50% lower cost than mainstream platforms. Key Benefits:

  • �� Dual generation modes (text-to-image & image-to-image).
  • 💰 20 free generations + $0.02 per additional request.
  • 🔄 Maintains character consistency across generations.
  • ⚡ Automated processing with 5-second polling.

Perfect for

Content creators, designers, marketers, developers, and anyone who needs to quickly create diverse AI visual content while maintaining consistent character identity across multiple generations.

Prerequisites

  • KIE.AI account and API key (Sign up here).
  • Active n8n instance with form submission capabilities.
  • AI prompts for image generation.
  • Reference images (optional, for image-to-image mode).

Quick Setup

1. Get API Key

Register at kie.ai/nano-banana and generate your API key.

2. Configure Form Fields

Set up these fields in your "On Form Submission" node:

  • model (Required): Choose between google/nano-banana for text-to-image or google/nano-banana-edit for image-to-image generation.
  • prompt (Required): Text description for your image generation.
  • img_url (Optional): Reference image URLs for image-to-image mode (up to 5 images, separate multiple URLs with commas).
  • api_key (Required): Your KIE.AI API key for authentication.
3. Test & Use
  1. Execute the workflow
  2. Access the generated form URL
  3. Fill in your details and submit
  4. Wait for processing (10-20 seconds)
  5. Results will be displayed automatically.

Usage Tips

Better Prompts: Include style (realistic, anime, cyberpunk), composition (close-up, wide shot), lighting (dramatic, soft), and mood (cheerful, mysterious). Example: "Realistic cyberpunk character with neon blue lighting, close-up composition, dramatic shadows" Common Uses:

  • Character design for games/stories
  • Social media content
  • Marketing materials
  • Product mockups

Troubleshooting

  • API Key Invalid: Verify key is correct and active.
  • Generation Fails: Check prompt length and content. Keywords: Nano Banana API, character-consistent images, text-to-image, image-to-image, KIE.AI, AI image generation, n8n template
