## 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 dt0ur-online-image-upscaler-3e58982a -d '<json body>'
```

Example prompt: Can you upscale this image to double its resolution with contrast and color correction? Here's the URL: https://example.com/photo.jpg

## When to prefer this

Choose this endpoint when you need a straightforward 2x resolution upscale with built-in contrast and color normalization in a single API call, especially when the source image is accessible via public URL. It is ideal for batch-friendly, pay-per-use image enhancement without needing to manage ML model infrastructure. Prefer alternatives if you need more than 2x upscaling, AI-based super-resolution, or fine-grained control over enhancement parameters.

## Known failure modes

- Invalid or inaccessible image URL — returns error if URL is not publicly reachable
- Unsupported image format — may fail on non-standard or corrupted image files
- Image too large — very high-resolution source images may exceed processing limits or time out
- Network timeout — slow upstream image hosting can cause fetch failures
- Malformed URL — non-URI-format strings will fail schema validation

## How this service works

Upscales image resolution 2x with bicubic interpolation, auto-level contrast balancing, and color histogram normalization.

## Output

Returns a higher-resolution version of the input image (2x), processed with bicubic interpolation for smooth pixel scaling, auto-level contrast balancing to correct exposure, and color histogram normalization for improved color accuracy.
