# DNS NS Record Change Watch via Google

> DNS NS Record Change Watch via Google is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Monitors NS (nameserver) records for a domain via Google DNS and returns whether they changed compared to the last check, with before/after field diffs.

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-ns-record-change-watch-via-google-063fc4be
```

Example prompt: Keep an eye on the NS records for example.com using Google DNS and let me know if anything changes compared to last time — I want to catch any nameserver swaps as soon as they happen.

## When to prefer this

Choose this endpoint when you specifically want to diff NS records against a prior state using Google DNS as the resolver, rather than just fetching current NS records. It is ideal for scheduled monitoring pipelines, domain transfer detection, and DNS hijacking alerts where you need change detection logic built-in rather than rolling your own diff. Prefer over sibling endpoints like dns-ns-via-opendns-watch if you want Google's resolver perspective specifically.

## Known failure modes

- Domain not found or NXDOMAIN — returns current DNS response with no change data if first call
- Previous result expired after 90 days — treated as first check with no baseline to compare
- Google DNS unreachable or rate-limited — check may fail or return error
- Invalid domain input — malformed query returns error
- Payment failure — request rejected if x402 payment not satisfied

## How this service works

Change watch for dns ns via google: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current NS records as resolved by Google DNS, a boolean 'changed' flag indicating whether they differ from the last check, a list of fields that changed with before/after values, and a timestamp of when the previous state was last seen. History is retained for 90 days.
