## 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 relaystation-image-sharpen-56578d27 -d '<json body>'
```

Example prompt: Can you sharpen this blurry product photo for me? The image is pretty soft — use a medium strength sharpening and return the crisped-up version.

## When to prefer this

Choose this endpoint when you need to programmatically sharpen soft, blurry, or low-definition images at scale — especially for scans, user-uploaded photos, or thumbnails. It is priced per megapixel, making it cost-efficient for small images, and supports adjustable strength so you can tune the enhancement. Prefer it over general image editing tools when you need a simple, single-purpose API call within an automated pipeline.

## Known failure modes

- Invalid or inaccessible image URL returns an error
- Unsupported image format may be rejected
- Strength parameter out of valid range returns a validation error
- Oversized image may exceed processing limits
- Network timeout for very large images
- Insufficient USDC balance causes payment failure via x402
