## 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-metadata-extractor-887d7837 -d '<json body>'
```

Example prompt: Can you fetch the metadata from https://example.com/blog/my-article and tell me the page title, description, and any Open Graph tags it has?

## When to prefer this

Choose this endpoint when you need structured HTML head metadata (title, description, Open Graph, Twitter cards, canonical, lang) from a single public HTTPS URL without writing custom scraping logic. Ideal for link preview/unfurling, SEO audits, and metadata enrichment pipelines. Prefer this over a full web scraper when you only need head-level metadata, not page body content.

## Known failure modes

- Non-HTTPS URLs (http, file, data, localhost, private IPs) are rejected with an error
- Response body exceeds 1 MB cap — truncated or rejected
- Request times out after ~10 seconds for slow servers
- More than 5 redirects causes failure
- URL is unreachable or returns a non-200 status
- Content-Type is not HTML — metadata fields may be absent or minimal

## How this service works

Fetch a public https URL and extract HTML head metadata ($0.005 USDC via x402). https only — http, file, data, localhost, and private IPs are rejected. Caps: 1 MB body, ~10s timeout, max 5 redirects. Returns JSON { url, final_url, content_type, title?, description?, canonical?, lang?, open_graph, twitter, warnings }.

## Output

Returns a JSON object containing the final resolved URL, content type, page title, meta description, canonical URL, language code, Open Graph metadata (og:title, og:description, og:image, etc.), Twitter card metadata, and any warnings (e.g. redirect notices, missing tags).
