## 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`):

```

Example prompt: Can you run an SEO audit on https://example.com/blog/my-post and check whether it has a proper title tag, meta description, canonical link, H1 structure, OpenGraph tags, structured data, and lang attribute?

## When to prefer this

Choose this endpoint when you specifically need on-page SEO metadata extraction (title, meta, H1, canonical, OG tags, structured data, lang) for a single URL. Prefer this over the full-suite audit endpoint when you only need SEO signals and want to minimize cost. Use instead of generic scraping when you need structured SEO-specific parsing rather than raw HTML.

## Known failure modes

- URL is unreachable or returns a non-200 status — audit cannot proceed
- URL blocks crawlers or requires authentication — elements may be empty or incomplete
- Page relies on client-side JavaScript rendering — server-side SEO tags may be absent
- Malformed URL input — returns validation error
- Timeout if target page is slow to respond

## How this service works

SEO audit of a web page (on-page SEO check) for any live URL or raw HTML: title tag, meta description, H1 heading structure, canonical link, OpenGraph and social tags, JSON-LD structured data, html lang attribute. Rule-by-rule findings with severity and what is missing or malformed.

## Output

Returns the extracted and evaluated on-page SEO elements for the given URL, including the page title, meta description content, H1 tag structure, canonical link href, OpenGraph tag values (og:title, og:description, og:image, etc.), structured data (JSON-LD or microdata), and the HTML lang attribute — along with any missing or problematic signals.
