# Sitemap Freshness Change Watch

> Sitemap Freshness 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).

## 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-change-watch-fa522a4b
```

Example prompt: Keep an eye on sitemap freshness for example.com — check it on a schedule and let me know if anything changes compared to last time, including exactly which fields changed and what the before and after values were.

## When to prefer this

Use this endpoint when you need scheduled, stateful change detection for sitemap freshness rather than a one-off check. It is ideal for SEO monitoring pipelines, site health dashboards, or agent workflows that need to react only when sitemap freshness actually changes, with structured before/after diffs rather than raw current state.

## Known failure modes

- Domain not provided or malformed — check will fail or return an error
- No previous result stored for the domain — first call will return changed: false with no diff
- Domain's sitemap is unreachable — freshness check may return an error state
- Payment not completed — endpoint returns 402 and check is not run
- Results older than 90 days are purged — comparison baseline lost

## How this service works

Change watch for sitemap freshness: 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 sitemap freshness changes. $0.01 per check.

## Output

Returns the current sitemap freshness result, a boolean indicating whether it changed since the last call, a list of exactly which fields changed with before and after values, and a timestamp of when it was last seen. Previous results are retained for 90 days per domain.
