How to Use Nano Banana 2 Lite

  1. Write a clear prompt: Describe the image you want in detail — subject, setting, lighting, style, and mood. The model's strong prompt adherence means specific descriptions produce tighter results.

  2. Choose an aspect ratio: Select from standard ratios (1:1, 16:9, 9:16, 21:9, etc.).

  3. Pick a resolution and output format: Choose 1K, 2K, or 4K resolution, and jpg for smaller files or png for lossless output.

  4. Submit via the API:

    curl -X POST https://api.muapiapp.com/api/v1/nano-banana-2-lite \\
  -H 'Authorization: Bearer YOUR_API_KEY' \\
  -H 'Content-Type: application/json' \\
  -d '{
    "prompt": "A sun-drenched Mediterranean courtyard with terracotta pots and bougainvillea, golden afternoon light, photorealistic.",
    "aspect_ratio": "16:9",
    "resolution": "1K",
    "output_format": "jpg"
  }'

  5. Poll for results: Use the returned request_id to poll the status endpoint until the image is ready. Expect results in approximately 4 seconds.

  6. Chain into edits: The generated image can be used as a reference input for Nano Banana 2 Lite Edit for further refinement, or passed to a video generation model for animation.
