## 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 stablestudio-generate-b54a59fc -d '<json body>'
```

Example prompt: Generate a cinematic 4K image of a lone astronaut standing on a rust-colored Martian plateau at sunset, with towering dust devils in the background — use a 16:9 widescreen format via Nano Banana Pro on StableStudio.

## When to prefer this

Choose this endpoint when you need high-resolution AI-generated images (up to 4K) specifically from the Nano Banana Pro model on StableStudio, especially when you need flexible aspect ratios (including widescreen 21:9 or portrait 9:16) and are comfortable with an async job-based workflow. Prefer over other StableStudio models when Nano Banana Pro's specific output style is desired.

## Known failure modes

- Empty or missing prompt returns validation error
- Invalid imageSize or aspectRatio enum value returns 400
- Insufficient USDC balance or payment failure returns 402
- Server overload may delay job creation
- Job creation succeeds but image generation fails asynchronously — need to check job status separately

## How this service works

Pay-per-generation AI image and video creation. No subscriptions ever.

## Output

Returns a JSON object with success=true, a jobId string for polling the result, status='pending', and a type field. The actual image is not returned immediately — the agent must poll or retrieve the job result using the jobId.

```json
{
 "prompt": "A serene landscape with rolling green hills, a clear blue sky, and wildflowers in the foreground during golden hour",
