DEVELOPER QUICKSTART
From API key to your first image.
Submit an asynchronous prediction with your Platform API key, then poll the returned task ID to retrieve the output.
# Set TOPVIEW_API_PLATFORM_KEY once. Preserve REQUEST_KEY and input for uncertain retries.
# For a NEW task only, unset REQUEST_KEY first. Save data.id to resume GET only.
: "${TOPVIEW_API_PLATFORM_KEY:?Set TOPVIEW_API_PLATFORM_KEY first}"
export REQUEST_KEY="${REQUEST_KEY:-$(uuidgen)}"
curl --fail-with-body 'https://platform-backend.topview.ai/api/v1/models/google/nano-banana-2-lite/text-to-image/predictions' \
-H "Authorization: Bearer $TOPVIEW_API_PLATFORM_KEY" \
-H "Idempotency-Key: $REQUEST_KEY" \
-H 'Content-Type: application/json' \
--data '{
"prompt": "A blue ceramic cup on a wooden table",
"aspect_ratio": "1:1"
}'
# Poll data.id until completed or failed.
curl --fail-with-body 'https://platform-backend.topview.ai/api/v1/predictions/REQUEST_ID' \
-H "Authorization: Bearer $TOPVIEW_API_PLATFORM_KEY"Sample matches the Nano Banana 2 Lite text-to-image request in Platform docs. Keep TOPVIEW_API_PLATFORM_KEY on your server only.
Step 1
Get Your API Key
Sign in to Topview API Platform and create an API key with the required model permissions. Keep your key secure and use it to authenticate API requests.
Step 2
Generate or Edit an Image
Submit a text prompt or upload reference images for editing. Configure the supported image settings, send your API request, and save the returned task ID.
Step 3
Retrieve Your Image
Check the task status until generation is complete. Retrieve the image URLs, review the final usage cost, and save your generated images.
BUILT FOR PRODUCTION WORKFLOWS
Simplify routine image generation and one-photo edits
Nano Banana 2 Lite works well for applications that need standard-size imagery and uncomplicated editing rather than 2K or 4K output controls.
Everyday Social Graphics
Generate simple square, portrait, or widescreen concepts for recurring social content and promotional posts.
Single-Photo Background Changes
Let users upload one image and request a new background, atmosphere, or visual treatment through the editing route.
Basic Product Listings
Create straightforward listing-style visuals and product presentation concepts when high-resolution selection is not required.
Lightweight Creative Features
Add prompt-based image generation and single-image editing to apps that do not need complex multi-reference workflows.
WHY TOPVIEW API
Clear pricing and fewer settings to manage
Use Topview to build around Lite’s limited, documented controls instead of presenting resolution or multi-image options the model does not expose.
One Standard Output Size
Keep the UI simple: Lite has no resolution parameter, so users do not need to choose between 1K, 2K, and 4K.
Review Per-Image Costs
Check the current listed charges for Text to Image and Image Editing, rather than inferring one price for every operation.
Test Three Practical Ratios
Try 1:1, 16:9, and 9:16 output in the Playground and keep the same options in your product.
Upgrade Only When Needed
Compare Lite with Nano Banana 2 and 2.1 if your workflow later requires higher resolutions or more reference images.
Nano Banana 2 Lite API FAQs
You can open the Nano Banana 2 Lite Playground to explore its settings. API usage is paid from your Platform USD balance, and promotional credits vary over time. Check your workspace's current eligibility and balance on Topview API Platform.
Topview API Platform lists Text to Image and Image Editing. Image Editing accepts one input image together with your prompt.
No. Nano Banana 2 Lite has no resolution parameter and returns one standard output size, so every image in the same mode has the same price. For 2K or 4K output, use Nano Banana 2 API or Nano Banana 2.1 API.
Each generated image is billed at one flat rate, and Text to Image and Image Editing currently share the same rate. Read charged_usd on the completed task for the final cost.
Create a Platform API key, submit a prediction to the Nano Banana 2 Lite endpoint with an Idempotency-Key, save the returned task ID, and poll until it completes. Then download the images promptly, because result URLs can expire. Keep your key server-side.
