# x402.agentutility.ai Nano Banana 2 Lite Image Generator

> x402.agentutility.ai Nano Banana 2 Lite Image Generator is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.08/call, status unknown (last checked 2026-10-20, last successful call 2026-08-18).

Generates SFW images using Venice's nano-banana-2-lite model via a low-cost fixed-model endpoint, returning a permanent fal-hosted PNG URL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-agentutility-ai-nano-banana-2-lite-image-generator-79a376b6 -d '<json body>'
```

Example prompt: Generate an image of a serene mountain lake at sunset with pine trees reflecting in the water — use the nano-banana-2-lite model so it's the cheaper option.

## When to prefer this

Choose this endpoint when you need low-cost SFW image generation specifically from the Venice Nano Banana model family, and the higher quality of nano-banana-pro is not required. Ideal for high-volume agent workflows where cost per image matters and the Nano Banana aesthetic is desired. Prefer over the pro variant when budget is constrained and image quality requirements are moderate.

## Known failure modes

- Prompt violates SFW content policy — endpoint enforces safe-for-work generation and will reject NSFW prompts
- Payment failure — x402 USDC payment on Base must succeed before generation begins; insufficient balance returns a payment error
- Model inference timeout — the nano-banana-2-lite model may occasionally time out under load
- Invalid or malformed prompt — empty or excessively long prompts may return a validation error
- fal hosting outage — if the upstream fal.ai hosting is unavailable, the image URL cannot be returned

## How this service works

Generates SFW images with Venice's nano-banana-2-lite model on a dedicated low-cost endpoint. Fixed-model route for cheaper Nano Banana / Google image generation where buyers want the Nano Banana family at a lower price than nano-banana-pro. Returns a permanent fal-hosted PNG URL.

## Output

A permanent fal-hosted PNG image URL corresponding to the generated image, ready to be embedded, downloaded, or passed to downstream tools without expiration concerns.
