## 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 402utils-html-url-to-pdf-renderer-155d9d98 -d '<json body>'
```

Example prompt: Convert this HTML invoice into an A4 PDF with 10mm margins on all sides, landscape orientation, and make sure background colors are included: <html>...</html>

## When to prefer this

Choose this endpoint when you need server-side, headless-Chrome-quality PDF rendering without running your own browser infrastructure. Ideal for generating invoices, receipts, reports, and tickets from HTML templates or snapshotting live web pages as PDFs. Preferred over client-side PDF libraries when pixel-perfect CSS fidelity and background graphics matter, and over full browser automation when you just need a single-document render at $0.01 per call.

## Known failure modes

- HTML exceeds 1 MB limit — request rejected
- URL is not publicly accessible or returns non-200 — rendering fails
- Invalid paper format enum value — validation error
- Margin values outside 0–100mm range — validation error
- Scale factor outside 0.5–2.0 range — validation error
- Both url and html provided simultaneously — mutually exclusive fields error
- JS-heavy page not fully rendered — use waitUntil: networkidle instead of load
- Payment not processed via x402 — 402 Payment Required response

## How this service works

Render HTML or a public web page into a pixel-perfect PDF using a headless Chrome browser. Send inline `html` (invoices, receipts, reports, tickets) or a `url` to snapshot; control paper size, orientation, margins, background graphics and scale. Returns the raw application/pdf bytes — no signup, no browser to run, pay per document.

## Output

Raw application/pdf binary bytes representing the rendered document — ready to save, stream, or attach to an email. No wrapper JSON, just the PDF file content.
