Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 fastx402-image-convert-f17b96d9
```

Example prompt: Take this image URL https://example.com/photo.png and convert it to webp format, resizing it to 800 pixels wide while keeping the aspect ratio and stripping any metadata.

## When to prefer this

Use this endpoint when you need a lightweight, no-account, pay-per-call image conversion and resizing service that supports webp, png, jpeg, and avif output, strips metadata, and returns a ready-to-use CDN URL. Ideal for AI agents that need on-the-fly image transformation without managing API keys or subscriptions.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Unsupported input image format (e.g. SVG, BMP) returns a format error
- Width or height outside 1-4096 range causes a validation error
- Payment not included or insufficient USDC results in 402 Payment Required
- Network timeout fetching the remote image
- Output URL expires after the indicated expires_at timestamp

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object containing a temporary URL to the converted image, the output file size in bytes, output dimensions (width and height), format string, MIME type, expiry timestamp, original input file size, and a boolean indicating whether metadata was removed.
