## How to call it through Zero

```sh
zero fetch --capability x402-seo-audit-9696e4b9
```

Example prompt: Can you run a full on-page SEO audit on https://example.com/blog/my-post and tell me the score plus any issues with the title, meta description, Open Graph tags, headings, and image alts?

## When to prefer this

Choose this endpoint when you need a fast, automated, single-page on-page SEO audit covering all standard signals (meta, Open Graph, Twitter cards, headings, images) in one call. It is ideal for agents that need a quick, scored health-check of a specific URL before publishing, after changes, or for competitive analysis. Prefer this over manual checklists or full-site crawlers when you need per-URL, real-time results with an actionable issues list without setting up a dedicated SEO platform.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status — audit cannot proceed
- URL returns a redirect loop or times out during fetch
- Malformed or non-URI input causes request rejection
- Dynamically rendered (JavaScript-heavy) pages may yield incomplete metadata if content is not in the initial HTML
- Rate limiting or payment failure (x402) preventing the call from completing

## How this service works

On-page SEO audit of any live URL: title/meta/canonical/robots, Open Graph + Twitter cards, headings, image alts, favicon — with a 0-100 score and actionable issues. Fetches and parses the live page on every call.

## Output

Returns a 0-100 SEO score along with a structured breakdown of on-page elements: title tag presence and content, meta description, canonical URL, robots meta directives, Open Graph tags (og:title, og:description, og:image, etc.), Twitter card tags, heading hierarchy (H1–H6), image alt attribute coverage, and favicon detection. Includes a list of actionable issues flagging missing, malformed, or suboptimal elements.
