## 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 rue-mossgate-dev-headless-chrome-renderer-76e118ba
```

Example prompt: Render https://example.com/invoice/123 as a full-page A4 PDF in portrait orientation using headless Chromium.

## When to prefer this

Choose this endpoint when you need server-side, JavaScript-rendered screenshots or document exports from a URL or HTML string, particularly when you need SSRF-safe rendering (no access to internal networks) and support for PDF paper/orientation options. Prefer it over client-side libraries when you need consistent Chromium rendering without managing browser infrastructure, or when you need to capture pages that require JS execution.

## Known failure modes

- SSRF guard blocks private/internal IP ranges or localhost URLs — returns an error if the URL resolves to a non-public address
- Invalid or unreachable URL results in a render failure or timeout
- Malformed raw HTML may produce blank or partial output without an explicit error
- Unsupported format enum value causes a schema validation error
- Very large or complex pages may time out during rendering
- Missing both url and html parameters returns a validation error

## How this service works

render a url or raw html to pdf, png or jpeg via headless chromium. ssrf-guarded, pure compute. body: {url|html, format:pdf|png|jpeg, full_page, landscape, paper}.

## Output

Returns the rendered file as binary output in the requested format — a PDF document, PNG image, or JPEG image — representing the fully rendered page including JavaScript-executed content, as produced by headless Chromium.
