## 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 hreflang-map-b99b54fd
```

Example prompt: Can you pull the hreflang map for https://example.com/about and tell me which languages and regions it targets, whether the x-default is set, and if there are any self-reference or duplicate issues?

## When to prefer this

Choose this endpoint when you need to audit, debug, or map the international SEO hreflang declarations of a specific page — particularly useful for SEO tooling, site crawlers, or agents validating multi-language/multi-region web presences. Prefer this over general HTML scrapers when you specifically need structured hreflang data with built-in consistency checks like self-reference validation and duplicate detection.

## Known failure modes

- Page URL is unreachable or returns a non-2xx status, resulting in no data extracted
- Page has no hreflang tags, returning an empty map
- Malformed hreflang attributes on the page may be skipped or flagged
- Network timeouts if the target page is slow to respond
- Payment not provided or insufficient USDC balance causes 402 rejection

## How this service works

hreflang map: every language and region alternate a page declares (link rel=alternate hreflang), the x-default, and consistency checks (self-reference present, duplicates). See which markets a site serves. $0.01 per page.

## Output

Returns a structured map of all hreflang alternate link declarations found on the page, including each language/region code and its corresponding URL, the x-default URL if present, whether a self-referencing hreflang tag exists, and any consistency issues such as duplicates or missing entries.
