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-cloud-ai-nano-banana-image-generation-ceeef941 -d '<json body>'
```

Example prompt: Generate 2 images of a neon-lit cyberpunk cityscape at night in 16:9 widescreen format using x402 Cloud's nano-banana image endpoint.

## When to prefer this

Choose this endpoint when you need pay-per-call AI image generation without a subscription, especially in autonomous agent pipelines, RAG systems, or creative automation workflows that require USDC micropayments via the x402 protocol. It is well-suited for applications needing Gemini-quality image generation at low per-call cost with support for multiple aspect ratios and batch image generation up to 4 images per call.

## Known failure modes

- Invalid or missing prompt returns 400 bad request
- Aspect ratio value not in allowed enum returns validation error
- numberOfImages outside 1-4 range returns validation error
- Insufficient USDC balance or x402 payment failure blocks the request
- Prompt too long (over 4000 characters) triggers maxLength validation error
- Service unavailability or upstream Gemini inference failure returns 5xx error

## How this service works

X402 Cloud AI Inference Endpoints is an agent-ready x402 API provider for Gemini, image, audio, video, realtime, and specialized AI inference workflows. We expose pay-per-call USDC endpoints designed for autonomous AI agents, application backends, trading bots, creative automation, and RAG systems with some of the lowest x402 AI inference prices available in the market.

## Output

A JSON object with a 'candidates' array where each candidate contains content parts with inlineData including a fileUri (URL to the generated PNG image) and mimeType of 'image/png'. Up to 4 candidate images can be returned depending on the numberOfImages requested.
