## 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 lordevo-canonical-indexability-check-3ce1ab5a
```

Example prompt: Can you check whether https://example.com/shoes?color=red is indexable, what its canonical URL is, and whether there are any hreflang or noindex issues?

## When to prefer this

Choose this endpoint when you need a focused, per-URL canonical and indexability check covering both HTML signals (canonical tag, meta robots, og:url, hreflang) and HTTP-level signals (Link header, X-Robots-Tag) in a single call. Prefer it over general SEO crawlers when you want lightweight, fast checks on individual URLs without needing a full site audit.

## Known failure modes

- Invalid or non-public URL returns an error
- URL times out or is unreachable, resulting in no data
- Pages behind authentication return incomplete or misleading signals
- Malformed canonical tags may be partially parsed
- Very slow pages may fail due to request timeout

## Output

A JSON object containing: the resolved canonical URL and its source (link tag or HTTP header), whether the page is indexable (indexable, noindex, or canonicalised_elsewhere), whether the canonical is self-referencing, a list of hreflang entries with language codes and validity flags, meta robots values, X-Robots-Tag value, og:url, and an array of detected issues (e.g. no_x_default, mismatched canonical).
