## 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 sitesignal-sitemap-inventory-870f00a0
```

Example prompt: Can you parse the sitemap at https://example.com/sitemap.xml and give me an inventory of all its URLs, last-modified dates, and path prefixes — pull up to 50 entries?

## When to prefer this

Use this endpoint when you need a fast, structured extraction of URLs and metadata from a public XML sitemap or sitemap index without building a custom parser. It is ideal for SEO audits, site structure analysis, competitor reconnaissance, and content freshness checks where you need a bounded, reliable URL inventory rather than a full recursive crawl.

## Known failure modes

- Invalid or unreachable sitemap URL returns an error with a description of the fetch failure
- Malformed or non-standard XML sitemap may result in partial or empty inventory
- Sitemap index with too many nested levels may be bounded and return only top-level entries
- Limit exceeded or out-of-range value returns a validation error
- Private or authentication-gated sitemaps return an access error

## How this service works

Parse one public XML sitemap or bounded sitemap index into a URL, last-modified, hostname, and path-prefix inventory.

## Output

Returns a structured inventory including the list of URLs found in the sitemap (up to the requested limit), their last-modified timestamps where available, the hostname, and path-prefix groupings, enabling downstream URL discovery, site auditing, or content freshness analysis.
