# DNS TXT via Google Change Watch

> DNS TXT via Google Change 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 TXT records for a domain via Google DNS (8.8.8.8) and returns whether the records changed since the last check, with before/after diffs.

## 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-google-change-watch-9f1af3a8
```

Example prompt: Watch the DNS TXT records for example.com via Google DNS and let me know if anything has changed since the last time we checked — show me what changed and what it looked like before.

## When to prefer this

Choose this endpoint when you need to detect changes in DNS TXT records specifically as seen by Google's public resolver (8.8.8.8), which is widely trusted and globally distributed. Prefer this over Mullvad or AliDNS watch variants when you want results from a resolver your audience or services are likely to use. Ideal for scheduled polling workflows where you want diff-based change alerts rather than raw record lookups.

## Known failure modes

- Domain not found or NXDOMAIN — returns empty records with no change data
- No previous result stored (first call) — returns current answer but changed=false or null with no before values
- Google DNS resolution failure or timeout — may return an error or empty response
- Domain input missing or malformed — request fails with validation error
- 90-day history expired — comparison baseline lost, treated as first call

## How this service works

Change watch for dns txt via google: 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 for the domain as answered by Google DNS, a boolean 'changed' flag, a list of fields that changed with before and after values, and a timestamp of when the current state was last seen. The previous result is retained for up to 90 days for comparison.
