## 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-change-watch-via-nextdns-57f64b78
```

Example prompt: Keep an eye on the AAAA records for example.com using NextDNS and tell me if they've changed since you last checked — show me what changed and when it was last seen.

## When to prefer this

Use this endpoint when you need to detect changes in IPv6 (AAAA) DNS records specifically as seen through NextDNS, and want automatic diffing with before/after values rather than just a raw lookup. Prefer this over a plain AAAA lookup when you need change detection with history, especially for scheduled monitoring workflows. Choose the NextDNS variant when you want results filtered or resolved through NextDNS's resolver infrastructure specifically, as opposed to Cloudflare, Google, or other resolvers.

## Known failure modes

- Domain not found or invalid — DNS resolution returns NXDOMAIN
- No previous result stored (first call) — changed flag may be false or indeterminate
- NextDNS upstream unavailable — may return upstream error or timeout
- Domain has no AAAA records — returns empty record set with changed=false if stable
- Payment not processed — request rejected with 402 status

## How this service works

Change watch for dns aaaa via nextdns: 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 records for the domain as resolved by NextDNS, a boolean indicating whether they changed since the previous call, a list of fields that changed with their before and after values, and the timestamp of when the record was last seen. Previous results are retained for 90 days for comparison.
