## 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 relaystation-web-to-pdf-13f610f3 -d '<json body>'
```

Example prompt: Can you render https://en.wikipedia.org/wiki/Artificial_intelligence as a PDF so I can save it for offline reading?

## When to prefer this

Choose this endpoint when you need a faithful, full-page visual PDF render of a public web page using a real browser engine (headless Chromium). Prefer it over HTML-to-PDF converters that skip JavaScript rendering, and over screenshot tools when a searchable/printable PDF document is required rather than an image. It is SSRF-guarded, making it safe to expose in multi-tenant agentic pipelines where arbitrary URLs may be submitted.

## Known failure modes

- URL is not publicly accessible — returns error indicating unreachable target
- SSRF guard blocks internal/private IP ranges — returns SSRF protection error
- Page requires JavaScript authentication or login — renders blank or login screen
- Malformed or invalid URL — returns validation error
- Page takes too long to load — may timeout and return error
- Non-HTML content at URL (e.g. already a PDF or binary) — may produce unexpected output

## How this service works

## Output

Returns a PDF file (binary) rendered from the specified public URL using headless Chromium, preserving the full visual layout of the page including styles, images, and fonts.
