## 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 saylor-innovations-data-desk-on-page-seo-audit-61058da9
```

Example prompt: Can you run an SEO audit on https://example.com/blog/my-article and tell me the score, letter grade, and the top issues I need to fix?

## When to prefer this

Choose this endpoint when you need a fast, structured on-page SEO snapshot of a single public URL—especially when you want a composite 0–100 score plus ranked issues covering titles, meta descriptions, headings, canonical, alt text, Open Graph, and link counts in one call. Prefer it over general web scrapers when you specifically need SEO-oriented analysis with severity-ranked recommendations rather than raw HTML or generic content extraction.

## Known failure modes

- URL is not publicly accessible (returns error or empty result)
- Paywalled or login-required pages cannot be crawled (limited/no data)
- Dynamic JavaScript-rendered pages may yield incomplete data if server-side rendering is absent
- Invalid or malformed URL input causes request failure
- Rate limiting or payment failure at $0.01 USDC per call
