# web-manifest-watch

> web-manifest-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 web app manifest for changes, returning current values, a changed flag, and field-level before/after diffs since the last check.

## 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 web-manifest-watch-0326d40c
```

Example prompt: Check the web manifest for example.com and tell me if anything has changed since the last time you checked — I want to know which fields changed and what their old and new values are.

## When to prefer this

Use this endpoint when you need automated, scheduled monitoring of a specific website's web app manifest and want structured field-level change detection with historical comparison. Prefer this over manually fetching and diffing manifests yourself when you want persistent state across calls (90-day memory), a clear changed flag, and explicit before/after diffs without building your own diffing logic.

## Known failure modes

- Domain unreachable or returns non-200 response — may return error or stale data
- No manifest found at the domain — returns empty or null manifest result
- First call for a domain has no previous snapshot to compare against — changed flag may be false or undefined
- Domain previously seen but 90-day retention expired — treated as a fresh first check
- Payment not received — request blocked before processing

## How this service works

Change watch for web manifest: 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 web app manifest reader changes. $0.01 per check.

## Output

Returns the current web app manifest fields, a boolean indicating whether anything changed since the last call for that domain, a field-level diff showing which properties changed with before and after values, and the timestamp of when the manifest was last seen. State is retained for 90 days.
