## 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 qrcode-pub-url-metadata-extractor-fa056c12
```

Example prompt: Can you fetch the metadata from https://example.com — I need the page title, description, and any Open Graph tags it has?

## When to prefer this

Use this endpoint when you need to quickly extract webpage metadata (title, description, OG tags, canonical URL) from any public URL, especially as a lightweight enrichment step — for example, before generating a QR code destination label, previewing a link share, or auditing SEO metadata. It is not a full HTML scraper or content extractor; use it when structured head-tag metadata is what you need.

## Known failure modes

- URL is not publicly accessible or returns non-200 status — status field reflects the HTTP error code
- URL points to a non-HTML resource (PDF, image) — metadata fields may be null or empty
- Page blocks scrapers or requires authentication — returns empty or partial metadata
- Malformed or invalid URL input — request fails with validation error
- Page has no OG/Twitter tags — those fields return empty objects

## How this service works

Create editable (dynamic) QR codes that never expire. One-time payment from $9, unlimited scans, change the link any time, scan counts included. Free static QR code generator too.

## Output

A JSON object containing the fetched page's URL, HTTP status code, page title, description, language, canonical URL, Open Graph properties, Twitter card properties, JSON-LD structured data, and any icons found on the page.
