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 quickbuild-website-screenshot-api-e78294e7
```

Example prompt: Take a full-page screenshot of https://stripe.com in dark mode at 1440px wide and give me the image as a PNG.

## When to prefer this

Choose this endpoint when you need a visual snapshot of a live public webpage — especially when you want configurable viewport dimensions, dark mode emulation, full-page capture, or raw image bytes vs. base64 JSON. At $0.008 per call it is cost-effective for one-off or low-frequency captures. Prefer this over headless browser services when you want a simple GET-based API with no browser infrastructure to manage.

## Known failure modes

- Invalid or non-public URL (IP addresses not allowed) returns an error
- URL times out during rendering if page is very slow and waitMs is insufficient
- JPEG quality or dimension parameters outside allowed ranges return validation errors
- Pages that block headless browsers may return blank or partial screenshots
- Very tall pages are capped at 8000px even if fullPage is true

## How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

## Output

Returns a JSON object containing the base64-encoded PNG or JPEG image of the page, the MIME type, page title, final URL after redirects, HTTP status of the main document, rendered width and height, whether it was a full-page capture, render time in milliseconds, and total byte size. If the format parameter is set to 'png' or 'jpeg', returns raw image bytes directly instead of JSON.
