# dns-aaaa-via-dnssb-watch

> dns-aaaa-via-dnssb-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 AAAA records via dns.sb and returns whether they changed since the last check, with before/after diffs and timestamps.

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-aaaa-via-dnssb-watch-288828c3
```

Example prompt: Keep an eye on the AAAA DNS record for example.com using dns.sb and let me know if it changes — I want to see what it was before and what it changed to.

## When to prefer this

Choose this endpoint when you specifically want change-detection semantics for AAAA (IPv6) DNS records using dns.sb as the resolver. It's ideal for scheduled monitoring workflows where you want to be alerted only when something changes, with structured before/after diffs. Prefer this over a plain AAAA lookup endpoint when you need historical comparison rather than just the current record value, and when dns.sb's resolver perspective (versus Google, Cloudflare, or OpenDNS) is relevant for your use case.

## Known failure modes

- Domain not found or has no AAAA record — returns empty or NXDOMAIN result
- First call for a domain returns no diff since there is no prior baseline
- Cached baseline older than 90 days is purged, resetting the comparison
- dns.sb upstream resolver unavailable — check may fail or return stale data
- Invalid or malformed domain input causes lookup failure

## How this service works

Change watch for dns aaaa via dnssb: 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 AAAA DNS records as answered by dns.sb, a boolean 'changed' flag indicating whether the result differs from the previous call for the same domain, the specific fields that changed with before/after values, and a timestamp of when the record was last seen. Previous results are retained for 90 days for comparison.
