## 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 klymax402-seo-analyzer-page-audit-5d5e2d1d
```

Example prompt: Run a full SEO audit on https://example.com and tell me the SEO score, any issues found, whether it has proper H1 tags, meta description, Open Graph tags, and how fast it loads.

## When to prefer this

Choose this endpoint when you need a quick, comprehensive on-page SEO snapshot of any publicly accessible URL — including meta tags, headings, Open Graph, canonical, schema types, and a computed SEO score — without needing a dedicated SEO platform subscription. It is ideal for automated auditing pipelines, competitor research, or pre-launch checks where pay-per-call pricing ($0.06/call) is more cost-effective than a monthly tool subscription.

## Known failure modes

- Invalid or unreachable URL returns error or empty/null fields
- Page behind authentication or firewall cannot be fetched
- Very slow pages may time out before returning results
- Pages that block crawlers (robots.txt or JS-only rendering) may return incomplete data
- Malformed URL input causes request failure
