## 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-txt-via-adguard-watch-567f9d3b
```

Example prompt: Keep an eye on the DNS TXT records for example.com using AdGuard DNS and tell me if anything has changed since the last time you checked — I want to see what was added, removed, or modified.

## When to prefer this

Choose this endpoint when you need to detect changes in DNS TXT records specifically as answered by AdGuard DNS (which applies security filtering). It is ideal for scheduled monitoring workflows where you want diffing and change history automatically managed rather than storing snapshots yourself. Prefer this over a plain TXT record lookup when your goal is alerting on change rather than just reading the current value.

## Known failure modes

- Domain not found or NXDOMAIN — returns empty record set with no change detected
- AdGuard DNS upstream unavailable — may return an error or stale response
- First call for a domain has no previous baseline — 'changed' will be false or undefined until a second call
- Domain input missing or malformed — request fails with a validation error
- No TXT records exist for the domain — returns empty records

## How this service works

Change watch for dns txt via adguard: 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 TXT records as answered by AdGuard DNS, a boolean 'changed' flag indicating whether the records differ from the previous call for the same domain, a list of fields that changed with before and after values, and a timestamp of when the previous state was last seen. State is retained for up to 90 days per domain.
