# Sitemap Page Count Change Watch

> Sitemap Page Count Change 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 domain's sitemap URL count over time, detecting changes by comparing current results against a stored baseline (retained 90 days) and reporting what changed, when, and the before/after values.

## 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-page-count-change-watch-76b90937
```

Example prompt: Keep an eye on how many URLs competitor-site.com declares in its sitemap and let me know if the count changes compared to last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in a domain's declared sitemap URL count over time without managing your own storage — it handles state comparison and 90-day retention automatically. Prefer it over one-off sitemap checks when you are running scheduled monitoring workflows, tracking SEO content growth, or auditing competitor site expansion. It is ideal for agentic loops that need to act only when something has changed.

## Known failure modes

- Domain has no sitemap — returns an error or zero count with no comparison
- Domain is unreachable or returns a non-200 response — check fails without a result
- No previous baseline exists (first call for domain) — changed flag may be false or indeterminate
- Sitemap is malformed or non-standard — URL count may be inaccurate or parsing fails
- Baseline has expired (older than 90 days) — no comparison available, treated as first call

## How this service works

Change watch for sitemap page count: runs the check and compares it with the result from your previous call for the same domain (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 how many pages does a site declare? counts urls across sitemap changes. $0.01 per check.

## Output

Returns the current sitemap URL count for the domain, a boolean indicating whether the count changed since the last call, a list of which fields changed with their before and after values, and the timestamp of when the baseline was last recorded. The comparison baseline is retained for 90 days.
