## 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 klymax402-image-resize-api-c32ce6fe
```

Example prompt: Can you resize the image at https://example.com/photo.jpg to 800 pixels wide and 600 pixels tall and give it back as a WebP?

## When to prefer this

Choose this endpoint when you need to resize a remotely hosted image by URL, optionally converting its format, and receive the result as a base64-encoded payload — especially useful in agent workflows where storing intermediate files is inconvenient and a direct in-memory image response is preferred.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Unsupported image format at source URL may fail
- Requested width or height of 0 or negative values may cause errors
- Network timeout if the source image URL is slow to respond
- Unsupported output format string (not png, jpeg, or webp) may return an error

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the resized image as a base64-encoded string, the output width and height in pixels, the MIME type, the output format, original size in bytes, resized size in bytes, and a compression ratio.
