Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-url-to-pdf-converter-3c279d9f -d '<json body>'
```

Example prompt: Can you convert https://example.com/invoice/12345 to a PDF using A4 portrait layout with print backgrounds enabled and give me the base64-encoded file?

## When to prefer this

Use this endpoint when you need a fully JS-rendered PDF from a live URL — not a static HTML snapshot. Ideal for pages with dynamic content (SPAs, dashboards, invoices generated client-side) where a simple HTML-to-PDF library would miss rendered content. Prefer this over image-capture siblings when you need a selectable/searchable document rather than a raster image.

## Known failure modes

- URL is unreachable or returns non-200 — ok:false with error message
- JavaScript-heavy page times out during render — partial or failed PDF
- Invalid page size or orientation parameter — 400 bad request
- Payment not provided or insufficient — x402 payment required response
- URL points to non-HTML content (e.g. binary file) — unexpected output or error

## How this service works

Convert any URL to a PDF through real headless Chromium — full JS rendering, print backgrounds, A4/Letter/Legal, portrait or landscape. Archive pages, generate reports and invoices from live web pages. $0.01 per call via x402.

## Output

A JSON object containing: ok (boolean success flag), b64 (base64-encoded PDF content), bytes (PDF file size in bytes), sha256 (hash for integrity verification), tookMs (render time in milliseconds), and contentType (application/pdf)
