Prerequisites
- An API key from iApp Technology
- Text prompt describing the image you want to generate
Quick Start
- Choose between Nanobanana (fast, 3 IC) or Nanobanana Pro (high-quality, 8 IC)
- Send a POST request with your prompt
- Receive base64-encoded image in response
Best Practices
- Be descriptive: "A Thai temple at sunset with golden spires" works better than "temple"
- Specify style: "minimalist", "photorealistic", "watercolor", etc.
- Include context: colors, lighting, composition, mood
