# sitemap-urls-watch

> sitemap-urls-watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors a website's sitemap URL list for changes, returning current URLs, a changed flag, before/after field diffs, and last-seen timestamp for change detection on a schedule.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-urls-watch-4c43bf01
```

Example prompt: Check the sitemap at https://example.com/sitemap.xml and tell me if anything has changed since the last time you checked — which URLs were added or removed.

## When to prefer this

Use this endpoint when you need to detect changes to a website's sitemap URL list on a recurring schedule without managing your own state — it handles the before/after comparison and stores prior results for 90 days. Prefer it over generic HTTP polling tools when you want structured field-level diffs specifically for sitemaps rather than raw page content changes.

## Known failure modes

- Target URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- Sitemap is malformed XML — parsing may fail or return partial URL list
- No previous check stored (first call) — 'changed' flag may be indeterminate or false by default
- Sitemap is too large — may timeout or return truncated results
- Previous check data expired after 90 days — baseline lost, comparison resets

## How this service works

Change watch for sitemap urls: runs the check and compares it with the result from your previous call for the same url (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when sitemap url list changes. $0.01 per check.

## Output

Returns the current list of sitemap URLs, a boolean 'changed' field indicating whether the list differs from the previous check (stored up to 90 days), a diff of exactly which fields changed with before/after values, and a timestamp of when the sitemap was last seen.
