# Sitemap Freshness Monitor

> Sitemap Freshness Monitor is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Loads a site's sitemap, counts URLs, finds newest/oldest lastmod dates, tracks URLs changed in the last 7/30 days, and detects added/removed URLs since the previous check.

## 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-freshness-monitor-0f71c592
```

Example prompt: Check the sitemap freshness for shopify.com — I want to know how many URLs they have, their newest and oldest lastmod dates, how many pages changed in the last 7 and 30 days, and whether any URLs were added or removed since the last time we checked.

## When to prefer this

Choose this endpoint when you need structured, quantified sitemap intelligence — particularly content velocity metrics (URLs changed per week/month) and delta tracking (pages added/removed over time). It is ideal for competitive content monitoring, SEO auditing, and client reporting workflows where you want recurring checks with diff history. Prefer it over generic web crawlers when you specifically need sitemap-derived freshness signals rather than full page content.

## Known failure modes

- Sitemap not found or not accessible — endpoint may return an error or empty result
- Site has no lastmod dates in its sitemap — date-based fields will be null or unavailable
- Sitemap index has more than 5 child maps — only the first 5 are expanded
- First-time call returns no diff data since no previous snapshot exists
- Invalid or unreachable domain — network error or non-200 response
- Malformed sitemap XML — parsing may fail or return partial results

## How this service works

Sitemap freshness: loads the site's sitemap (index expanded, up to 5 child maps), counts URLs, finds the newest and oldest lastmod dates, how many URLs changed in the last 7 and 30 days, and, when called repeatedly, how many URLs were added or removed since your previous call (kept 90 days). Content-velocity monitoring for competitors and clients. $0.01 per check.

## Output

Returns the total URL count across the sitemap (including expanded sitemap index up to 5 child maps), the newest and oldest lastmod dates found, counts of URLs modified in the last 7 and 30 days, and — when called repeatedly — the number of URLs added or removed since the previous call (history retained for 90 days).
