# dns-ns-via-opendns-watch

> dns-ns-via-opendns-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 DNS NS record changes for a domain via OpenDNS, returning current records plus a change diff compared to the previous check (stored 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-ns-via-opendns-watch-44e9ca36
```

Example prompt: Keep an eye on the nameservers for example.com via OpenDNS and let me know if anything changes — tell me exactly what was different and when it was last seen.

## When to prefer this

Use this endpoint when you need to detect changes in DNS NS records specifically as resolved by OpenDNS, with automatic diffing against a stored baseline. Prefer this over a plain NS lookup endpoint when your goal is change detection or alerting rather than simply reading current values. Ideal for scheduled monitoring pipelines where you want to be notified only when nameservers actually change.

## Known failure modes

- Domain not provided or malformed — returns error without running the check
- No previous result stored (first call) — 'changed' may be indeterminate or treated as new baseline
- OpenDNS upstream timeout or error — check fails to return current records
- Domain has no NS records — returns empty record set
- 90-day retention window expired — previous state lost, comparison not possible

## How this service works

Change watch for dns ns via opendns: 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 answered by OpenDNS, a boolean 'changed' flag indicating whether the records differ from the previous call for the same domain, a list of changed fields with before/after values, and a timestamp of when the previous state was last seen. Previous results are retained for up to 90 days.
