# DNS TTL Audit Change Watch

> DNS TTL 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).

Monitors DNS TTL audit results for a domain, returning the current audit, a changed flag, and field-level before/after diffs compared to the previous call (retained 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 dns-ttl-audit-change-watch-2d1560b8
```

Example prompt: Keep an eye on the DNS TTL audit for example.com — check it now and tell me if anything has changed compared to the last time it was checked, including exactly which fields changed and what the old and new values are.

## When to prefer this

Choose this endpoint when you need to detect changes in DNS TTL audit results over time rather than just fetching a one-time snapshot. It is ideal for scheduled monitoring workflows where you want field-level diffs and before/after values without managing your own state. Prefer it over a plain audit endpoint when you need change detection, historical comparison, and alerting built in.

## Known failure modes

- Missing or invalid domain parameter returns an error
- Domain with no prior audit history returns changed=false with no diff on first call
- Network or DNS resolution failure may return an error or empty audit result
- Calls beyond the 90-day retention window lose historical comparison baseline
- Payment failure via x402 prevents the check from running

## How this service works

Change watch for dns ttl audit: 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 dns ttl audit changes. $0.01 per check.

## Output

Returns the current DNS TTL audit result for the domain, a boolean 'changed' flag indicating whether the result differs from the previous call, a field-level diff showing exactly which fields changed with their before and after values, and a timestamp for when the previous result was last seen. Previous results are retained for 90 days.
