## 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 utunumus-studio-image-upscaler-d4d434bd -d '<json body>'
```

Example prompt: Can you upscale this image I just sent you? It's low resolution and I need a crisp, high-res version — run it through the Utunumus Studio upscaler.

## When to prefer this

Choose this endpoint when you need pay-per-call image upscaling without a subscription, especially in agentic pipelines where you want micro-payments settled on Base via x402. Ideal when you need to upscale individual images on demand without committing to a SaaS plan.

## Known failure modes

- Invalid or malformed base64 string returns a 400 error
- Image too large or unsupported format may be rejected
- Payment failure or insufficient USDC balance causes 402 response blocking the request
- Network timeout if image payload is very large
- Corrupted input image yields processing error

## How this service works

## Output

A higher-resolution version of the input image, returned as binary image data or base64, with enhanced detail and sharpness compared to the original low-resolution input.
