## 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 image-resize-api-925ac4c9 -d '<json body>'
```

Example prompt: Can you resize this image to 800 by 600 pixels and return the result as a PNG in base64 format?

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call image resizing service that returns base64-encoded output compatible with downstream AI pipelines or web applications. It is well-suited for agents that need to preprocess images on-the-fly without managing dedicated image processing infrastructure. Ideal when you need a consistent JSON response with width, height, and format metadata alongside the image data.

## Known failure modes

- Missing or malformed 'input' field in request body returns validation error
- Unsupported image format or corrupted image data may cause processing failure
- Extremely large images may time out or exceed memory limits
- Invalid bodyType enum value causes request rejection
- Missing required nested fields (type, method, bodyType, body) results in schema validation error

Image processing for AI agents

## Output

Returns a JSON object containing the processed image as a base64-encoded string (key: 'image'), along with the output width, height, and format (e.g. 'png'). Example: {"image": "base64...", "width": 800, "height": 600, "format": "png"}.
