## 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 agent402-tools-technical-seo-audit-cb8218b9 -d '<json body>'
```

Example prompt: Can you run a full technical SEO audit on https://mysite.example.com and tell me if search engines and AI crawlers can actually index it — including TLS health, robots policy, sitemap, and OpenGraph tags?

## When to prefer this

Use this endpoint when you need a bundled, one-call technical SEO audit covering reachability, TLS, robots policy, sitemap, meta/OpenGraph tags, and link graph — especially when you want to know if both traditional search engines and AI crawlers can index a page without running multiple separate checks.

## Known failure modes

- Invalid or unreachable URL returns an error indicating the page could not be fetched
- Non-HTTPS URLs may be rejected or flagged as unsupported
- Rate limiting or payment failure blocks the request
- Pages behind authentication or firewalls may return incomplete audit results
- Malformed sitemap or robots.txt may cause partial results

## How this service works

Bundled execution of the Technical SEO audit workflow - Can search engines and AI crawlers actually index this page? One pass over reachability, TLS, robots policy, sitemap health, meta/OpenGraph tags, and the on-page link graph. One x402 payment runs 6 underlying tools (http-check, tls-cert, robots-check, sitemap, meta, http-headers); partial-success per step.

## Output

A structured report covering: reachability and HTTP status of the page, TLS certificate validity, robots.txt crawl policy (including AI crawlers), sitemap health, meta and OpenGraph tag completeness, and the on-page link graph — all in a single response.
