## 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 sitemap-validate-5e06500b
```

Example prompt: Can you validate the sitemap at https://example.com/sitemap.xml and tell me if it's well-formed, whether any URLs are broken or duplicated, and if it exceeds the 50,000-URL or 50 MB limits?

## When to prefer this

Use this endpoint when you need to programmatically audit a sitemap for Sitemaps protocol compliance before submission to search engines, during CI/CD pipelines, or when diagnosing SEO crawl issues. Prefer this over generic XML validators because it enforces sitemap-specific rules: 50,000-URL cap, 50 MB limit, absolute URLs, same-host loc constraints, lastmod ISO 8601 format, valid changefreq/priority enumerations, gzip support, and correct namespace declarations.

## Known failure modes

- Sitemap URL is unreachable or returns non-200 HTTP status — returns error indicating fetch failure
- Sitemap URL points to non-XML or non-sitemap content — returns parse error
- Sitemap file exceeds 50 MB limit — flagged as error
- Network timeout when fetching large or slow sitemaps
- Gzip encoding errors if sitemap is malformed gzip

## How this service works

Sitemap validator: fetches a sitemap or index, checks well-formedness, namespace, type (urlset/sitemapindex), counts entries, validates loc URLs (absolute, same host, no duplicates), lastmod formats, changefreq/priority values, the 50,000-URL and 50 MB limits, gzip, and lists the first errors. Returns valid true/false with error and warning lists. $0.01 per sitemap.

## Output

Returns a JSON object with a top-level valid boolean, a list of errors (e.g. malformed XML, out-of-spec namespaces, non-absolute URLs, cross-host URLs, duplicate locs, bad lastmod formats, invalid changefreq/priority values, entries exceeding 50,000 or file size exceeding 50 MB), and a list of warnings. Also includes the detected sitemap type (urlset or sitemapindex), entry count, and gzip status.
