## 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 agentsvc-io-image-resize-api-869446d9 -d '<json body>'
```

Example prompt: Resize the image at https://example.com/photo.png to 800 pixels wide and 600 pixels tall, convert it to webp format at quality 85, fitting it inside those bounds.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically resize or reformat images on a per-call, pay-as-you-go basis without managing API keys or subscriptions. Particularly suited for agents handling user-uploaded content, generating thumbnails, or preparing images for specific display contexts. Supports both URL-based and base64 inputs, making it flexible for pipelines where the image is already in memory.

## Known failure modes

- Image URL is not publicly accessible or returns a non-image response
- Image exceeds the 15 MB size limit
- Requested width or height exceeds the 4096-pixel maximum
- Invalid or unsupported image format in the source file
- Network timeout fetching the source image URL
- Malformed base64 image data provided
