# third-party-scripts-watch

> third-party-scripts-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 third-party script inventory on a webpage and returns a diff (changed true/false, before/after field values) compared to the previous check stored for that URL.

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 third-party-scripts-watch-99780b17
```

Example prompt: Keep an eye on https://example.com for any changes to its third-party scripts — check it now and tell me if anything has changed since the last time you looked, including exactly which scripts were added or removed.

## When to prefer this

Choose this endpoint when you need automated, differential monitoring of third-party scripts on a specific URL over time, rather than a one-shot inventory. It is ideal for security and compliance use cases where detecting additions or removals of third-party scripts (tracking, analytics, ad networks) is critical, and where you want to receive a structured before/after diff rather than just a raw inventory snapshot. Prefer this over a bulk or one-time check when running on a schedule to catch supply chain attacks or unauthorized script injections.

## Known failure modes

- URL is unreachable or returns non-200 status — check may return an error or incomplete inventory
- No previous snapshot exists (first call for a URL) — `changed` will be false or undefined, no diff available
- URL content is behind authentication or bot protection — third-party scripts may not be fully detected
- Stale comparison if last check was more than 90 days ago — historical snapshot has expired
- Payment failure via x402 protocol — call is rejected before any check is performed

## How this service works

Change watch for third party scripts: 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 third-party script inventory changes. $0.01 per check.

## Output

Returns the current third-party script inventory for the given URL, a boolean `changed` flag indicating whether anything has changed since the last call for that URL, a detailed diff listing exactly which fields changed with before and after values, and a timestamp of when the URL was last checked. Historical comparison data is retained for 90 days.
