## How to call it through Zero

```sh
zero fetch --capability seo-on-page-audit-2dda5221
```

Example prompt: Can you run an on-page SEO audit on https://www.example.com/landing-page and give me a score, flag what's missing or broken, and write better title and meta description replacements if they're weak?

## When to prefer this

Choose this endpoint when you need a fast, affordable ($0.15), structured on-page SEO audit with a numeric score and actionable AI-written fixes for a single URL. Prefer it over the deep audit sibling when you don't need heading hierarchy analysis or internal/external link data and want quicker results. Ideal for pre-publish checks, client reporting, or automated SEO monitoring pipelines.

## Known failure modes

- URL is not publicly accessible (returns error or timeout)
- URL returns non-HTML content (PDF, image) — checks may be incomplete
- Paywalled or bot-blocked page prevents crawl
- Invalid or malformed URL provided
- Rate limiting or payment failure at $0.15 USDC per call

## Output
