## 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 md-fastdb-in-screenshot-url-to-png-jpeg-7b126061 -d '<json body>'
```

Example prompt: Take a full-page retina screenshot of https://example.com and give me a PNG — wait 2000ms after load to make sure everything has rendered.

## When to prefer this

Choose this endpoint when you need a pixel-accurate, JS-rendered visual capture of a live public webpage — especially SPAs that require JavaScript execution. Prefer it over static HTML scrapers when visual proof, archival screenshots, or element-level captures are needed. Use over PDF conversion when a raster image (not a printable document) is the desired output.

## Known failure modes

- Private or localhost URLs are rejected — only public hosts are supported
- Selector not found on page results in an error or empty capture
- Timeout if waitMs is set too high or the page never finishes loading
- JPEG quality parameter ignored when format is PNG
- Width/height outside 320–1920 range returns validation error
- Non-HTTP/HTTPS URLs are rejected

## How this service works

Screenshot any URL as PNG/JPEG through real headless Chromium — full JS rendering (SPAs work), fullPage or viewport, CSS-selector element capture, retina scale. Agent eyes for the web: verify pages visually, archive proof, capture previews. $0.005 per call via x402.

## Output

Returns either a JSON object wrapping a base64-encoded image string (default) or raw binary image bytes, in PNG or JPEG format, representing the fully JS-rendered visual state of the requested URL at the specified viewport and scale.
