# page-links-status-watch

> page-links-status-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 and detects changes in the HTTP status of the first 20 links on a given web page, comparing current results against the previous check stored for up to 90 days.

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 page-links-status-watch-2cd6c026
```

Example prompt: Keep an eye on https://example.com/resources and let me know whenever the status of any of its links changes — tell me exactly which links changed and what their old vs new status codes are.

## When to prefer this

Choose this endpoint when you need to detect changes in link statuses on a page over time, not just perform a one-shot check. It is ideal for scheduled monitoring workflows where you want to be told specifically what changed (with before/after values) rather than parsing raw link lists yourself. Prefer this over generic link checkers when change diffing and state persistence across calls are required.

## Known failure modes

- Page URL is unreachable or returns an error — may return no link data
- No previous check exists for the URL (first call) — changed will be false or null with no diff
- Page has no links — returns empty link list
- Stored previous result has expired (older than 90 days) — treated as first call
- Page blocks crawling (robots.txt or firewall) — may return partial or empty results

## How this service works

Change watch for page links status: 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 status of the first 20 links on a page changes. $0.01 per check.

## Output

Returns the current HTTP status of up to 20 links found on the given page, a boolean indicating whether any statuses changed since the previous call, a list of exactly which fields changed with before and after values, and the timestamp of when the previous result was last seen. Previous results are retained for 90 days.
