## 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-cloudflare-ea57444d
```

Example prompt: Keep an eye on the AAAA records for example.com using Cloudflare and let me know if anything has changed since the last time you checked — show me what was different, what it was before, and what it is now.

## When to prefer this

Choose this endpoint when you need to detect changes in IPv6 (AAAA) DNS records specifically as resolved by Cloudflare, and you want a stateful diff (before/after) rather than just the raw current record. Ideal for scheduled polling workflows where you want to be alerted only when something actually changes, without maintaining your own state store. Prefer over raw DNS lookup endpoints when change detection is the goal.

## Known failure modes

- Domain not found or NXDOMAIN — returns NOERROR/NXDOMAIN response with empty records
- No previous record stored (first call) — returns current result with changed=false or null baseline
- Domain is malformed or missing — request rejected
- Payment not included or insufficient — x402 payment required error
- Cloudflare DoH upstream timeout — may return error or degraded response

## How this service works

Change watch for dns aaaa via cloudflare: 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 record answer from Cloudflare DoH, a boolean 'changed' flag indicating whether the result differs from the previous call for the same domain, a list of fields that changed with before/after values, and the timestamp when the record was last seen. Previous results are retained for 90 days.
