# SEO Audit Change Watch

> SEO Audit 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).

Runs an SEO audit on a URL, compares it to the previous result (stored 90 days), and returns whether anything changed along with a before/after diff of changed fields.

## Facts

- Endpoint: GET https://intel.rallylive.ca/watch/seo-audit
- Price: $0.02/call
- Payment: x402
- Status: unknown

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 seo-audit-change-watch-91e081c0
```

Example prompt: Check the SEO audit for https://example.com and tell me if anything has changed since the last time you checked — specifically the score and which issues are different now.

## When to prefer this

Choose this endpoint when you need automated, scheduled SEO monitoring with change detection rather than a one-off audit. It is ideal when you want to know not just the current SEO state but precisely what changed since last check, with before/after field-level diffs. It suits agents running on a schedule to catch SEO regressions or improvements without storing the previous state themselves, since intel.rallylive.ca retains snapshots for 90 days.

## Known failure modes

- URL unreachable or returns non-200 status — audit may fail or return incomplete results
- No previous snapshot exists (first call) — 'changed' will be false/null with no diff
- Snapshot older than 90 days has expired — treated as first call with no comparison
- Malformed or missing URL parameter — returns validation error
- Payment not fulfilled (x402) — request rejected before audit runs

## How this service works

Change watch for seo audit: 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 seo audit of a web page with a 0-100 score and a ranked issues list changes. $0.01 per check.

## Output

Returns the current SEO audit result (0–100 score plus ranked issues list), a boolean 'changed' flag, a field-level diff showing exactly which fields changed with before and after values, and a timestamp of when the previous result was last seen. Previous snapshots are retained for 90 days.
