## 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 24k-labs-image-metadata-extractor-68d1c28c -d '<json body>'
```

Example prompt: Can you check this image for me — https://example.com/photo.jpg — and tell me its format, dimensions, aspect ratio, whether it has transparency, and how many bytes it is?

## When to prefer this

Choose this endpoint when you need lightweight, structured metadata about an image — format, dimensions, mode, aspect ratio, transparency, and byte size — without performing heavier operations like object detection or OCR. It is ideal for pre-processing checks (e.g. validating upload requirements), audit pipelines, or any workflow where you need image properties quickly and cheaply at $0.002 per call.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Unsupported image format returns a format error
- Network timeout if the image host is slow to respond
- Extremely large images may exceed processing limits
- Malformed request body missing the image reference returns a 400-level error

## How this service works

Report format, dimensions, mode, aspect ratio, transparency, and byte size of an image.

## Output

Returns a structured object containing the image format (e.g. PNG, JPEG, WEBP, GIF, BMP), pixel dimensions (width × height), color mode (e.g. RGB, RGBA, grayscale), aspect ratio, a boolean indicating transparency support, and the file's byte size.
