# dns-ns-via-alidns-watch

> dns-ns-via-alidns-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 records for a domain via AliDNS and detects changes compared to the previous check, returning diff details and a changed flag.

## Facts

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-alidns-watch-7dabe274
```

Example prompt: Watch the NS records for example.com using AliDNS and tell me if they've changed since the last check — show me what changed and when it was last seen.

## When to prefer this

Choose this endpoint when you specifically want to monitor NS record changes as seen from AliDNS (223.5.5.5), a Chinese anycast resolver useful for validating DNS propagation from Asian networks. Prefer this over one-shot NS lookup endpoints when you need change detection with diffing and historical comparison. Use when you need to schedule recurring checks and receive alerts on nameserver changes.

## Known failure modes

- Domain not found or invalid domain name returns an error or empty record set
- No previous check stored (first call for a domain) means 'changed' cannot be computed and may return a baseline result
- AliDNS upstream unavailable causes lookup failure
- Rate limiting or payment failure blocks the check
- Domain with no NS records returns empty result

## How this service works

Change watch for dns ns via alidns: 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 AliDNS, a boolean 'changed' flag indicating whether they differ from the previous check, a list of fields that changed with before and after values, and a timestamp of when the records were last seen. Previous check results are retained for 90 days.
