# dns-ns-via-cleanbrowsing-watch

> dns-ns-via-cleanbrowsing-watch 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 CleanBrowsing DNS and returns whether they changed since the last check, with before/after field diffs.

## 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-via-cleanbrowsing-watch-98b82678
```

Example prompt: Keep an eye on the nameservers for example.com using the CleanBrowsing DNS watch — let me know if they've changed since the last time you checked.

## When to prefer this

Choose this endpoint when you specifically want change detection for NS records using CleanBrowsing as the resolver, and you need persistent state comparison (up to 90 days) without managing your own storage. Prefer it over plain NS lookup endpoints when your goal is alerting or drift detection rather than a one-time query. It is particularly suited to scheduled polling workflows where you want to detect domain hijacking, delegation changes, or DNS migrations.

## Known failure modes

- Domain not found or NXDOMAIN — NS query returns empty or error response
- No prior result stored — first call cannot produce a meaningful diff, changed will be false or undefined
- CleanBrowsing DNS resolver unavailable — upstream timeout or error
- Invalid domain format in query — query rejected
- 90-day history expired — previous result no longer available for comparison

## How this service works

Change watch for dns ns via cleanbrowsing: 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 for the domain as resolved by CleanBrowsing DNS, a boolean 'changed' flag indicating whether the result differs from the previous call (stored for up to 90 days), a list of fields that changed with before/after values, and a timestamp of when the records were last seen.
