## 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 url-to-pdf-converter-screenshot-api-91391b69 -d '<json body>'
```

Example prompt: Can you convert https://en.wikipedia.org/wiki/Artificial_intelligence to a PDF in Letter format and give me the base64-encoded file?

## When to prefer this

Choose this endpoint when you need a full print-emulated PDF of a web page — not just a screenshot — with control over paper size (A4, A3, Letter, Legal, Tabloid). It is ideal for archiving reports, invoices, contracts, or any content where PDF format and print layout matter. Prefer this over the sibling screenshot endpoints when the output must be a PDF rather than a PNG image.

## Known failure modes

- Internal/loopback hostnames (e.g. localhost, 127.0.0.1) are rejected with an error
- Invalid or unreachable URLs return an error
- Unsupported format values outside A4/A3/Letter/Legal/Tabloid cause a validation error
- Pages that require authentication may render blank or incomplete
- Very large pages may time out during rendering
- Invalid wait_until values cause a validation error

## How this service works

Render an http(s) URL to a PDF (A4/A3/Letter/Legal/Tabloid) with print emulation; returns a JSON envelope with the PDF base64-encoded under pdf_base64, plus final_url, title, format, and size.

## Output

A JSON object containing: pdf_base64 (the full PDF file base64-encoded as a string), final_url (the resolved URL after any redirects), title (the HTML page title), format (the paper size used), and size (the byte size of the PDF).
