## 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 fastaf-web-page-screenshot-99564786
```

Example prompt: Can you take a full-page screenshot of https://example.com and give me the image in PNG format at 1280px wide?

## When to prefer this

Use this endpoint when you need a pixel-accurate visual capture of a public web page — for auditing layouts, generating thumbnails, archiving visual state, or verifying a deployment. It supports configurable viewport size, image format (PNG/JPG/WebP), quality, and full-page capture. Prefer it over HTML-extraction endpoints when the visual appearance matters, not just the text content.

## Known failure modes

- Private, internal, or login-gated URLs are refused and return an error
- Invalid or malformed URLs cause a rejection without charge
- Network timeouts or unreachable hosts result in a failed (uncharged) request
- wait_until=networkidle may time out on pages with persistent background requests
- Very tall full-page captures may hit size or memory limits

## How this service works

Web page screenshot API for AI agents: capture a website URL as PNG, JPEG or WebP image bytes for visual inspection and page archiving. Supports full-page capture, viewport dimensions and load readiness; the discovery example is a base64-encoded PNG, not a JSON response. Provided by FastAF Website Screenshots. Price: $0.005000 USDC per successful call.

## Output

Raw binary image bytes (PNG, JPG, or WebP depending on the format parameter) representing a browser-rendered screenshot of the requested URL. The image reflects the page at the moment of capture, rendered to the specified viewport dimensions, with optional full-page scroll capture.
