HTTP status codes

Code	Description
200	Default HTTP response for both success and many business errors. Only outer JSON code 0 indicates success or asynchronous acceptance; inspect data for the result.
429	Execution admission rate limit; honor Retry-After when present.
503	Execution admission is temporarily unavailable; honor Retry-After when present.
Opt-in	X-Nexscope-Http-Status: semantic maps controller-handled business errors to HTTP status on run and task routes. Pre-authentication failures, such as a missing or invalid API key (code 11209, including an incomplete or corrupted copy) or an expired website login session (code 12001), may still return HTTP 200 before this mapping. Always check the outer JSON code; malformed requests and infrastructure failures may also return non-200 HTTP responses.

Question

What can Nano Banana 2 Lite Image Generation produce, and how might I use the result?

AI answer

Nano Banana 2 Lite accepts a prompt for image generation and can use up to 10 reference images. It supports 1–10 requested outputs and several aspect ratios, with 1K as its only documented resolution. The example response is a pending task rather than a completed image.

Data category	Documented fields	What the values mean
Task reference	`data.taskId`	Identifier for retrieving the task outcome.
Processing state	`data.status`	The example's `PENDING` value shows that generation is still in progress.
Generated-result placeholder	`data.result`	The example is `null`; the provided documentation does not describe finished image fields or a media URL.

Prompt for a 1K square product image concept and inspect the completed output before using it in a draft listing.
- Prompt example: “I am preparing product creative for an online listing. Could you prompt for a 1K square product image concept and inspect the completed output before using it in a draft listing? Ask me for required source images or text, and show the finished result only after the task completes.”
Provide a reference image to explore a new background or composition for the same product.
- Prompt example: “I am preparing product creative for an online listing. Could you provide a reference image to explore a new background or composition for the same product? Ask me for required source images or text, and show the finished result only after the task completes.”
Request several outputs to compare ideas for a small set of campaign visuals.
- Prompt example: “I am preparing product creative for an online listing. Could you request several outputs to compare ideas for a small set of campaign visuals? Ask me for required source images or text, and show the finished result only after the task completes.”
Use a supported vertical or wide aspect ratio to develop a visual for that placement. Retrieve the finished task result before treating an image as produced.
- Prompt example: “I am preparing product creative for an online listing. Could you use a supported vertical or wide aspect ratio to develop a visual for that placement? Ask me for required source images or text, and show the finished result only after the task completes.”
