## 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-mullvad-2a02b471
```

Example prompt: Watch the AAAA records for example.com using Mullvad DNS and let me know if anything has changed since the last time you checked.

## When to prefer this

Use this endpoint when you specifically want to monitor DNS AAAA (IPv6) records as seen through Mullvad's DNS resolver, and need a diff-aware comparison against a prior snapshot rather than just a raw lookup. Prefer it for change-detection workflows, scheduled alerting pipelines, or security monitoring where knowing what changed between observations matters as much as the current value.

## Known failure modes

- Domain not provided or invalid — query fails with missing parameter error
- Domain has no AAAA records — returns empty record set with NOERROR or NXDOMAIN
- Mullvad DNS resolver unavailable — upstream timeout or error
- No previous check stored for this domain — 'changed' will be null or false with no before values
- Check older than 90 days — previous result has expired, treated as first-time check

## How this service works

Change watch for dns aaaa via mullvad: 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 Mullvad DNS, a boolean indicating whether the result changed since the last call for the same domain (stored for 90 days), a list of fields that changed with before/after values, and the timestamp of when the previous result was last seen.
