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-dev-dopamint-ai-eb9e03a7 -d '<json body>'
```

Example prompt: Generate an image of a futuristic neon-lit cityscape at night using nano-banana-pro, 2K resolution, 16:9 aspect ratio, PNG format.

## When to prefer this

Choose this endpoint when you need images generated by the nano-banana-pro model specifically, which may differ in style or quality from nano-banana or stable-diffusion-v35-large siblings on the same host. Prefer this when you need async job-based generation with status polling, support for up to 4K resolution, and multiple aspect ratios including portrait and landscape. Use this over the nano-banana variant when you want the pro-tier model quality at the $0.20 price point.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Invalid resolution value (e.g. '8K') returns a schema validation error
- Invalid aspect_ratio value returns a validation error
- Payment failure or insufficient USDC balance returns a 402 Payment Required error
- Model unavailable or overloaded may return 503 or timeout
- Polling statusUrl may return pending status if job is still processing

## How this service works

Generate image using nano-banana-pro

## Output

Returns a JSON object containing a unique jobId, a human-readable message with a status tracking URL, the statusUrl itself for polling job completion, a timestamp, and an HTTP status code. The image is not returned directly — the agent must poll the statusUrl to retrieve the final result.
