# dns-txt-via-cleanbrowsing-watch

> dns-txt-via-cleanbrowsing-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 CleanBrowsing DNS and returns whether they changed since the last check, with before/after field 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-cleanbrowsing-watch-77295363
```

Example prompt: Watch the DNS TXT records for example.com using CleanBrowsing and tell me if anything has changed since the last time you checked — show me what fields changed and what the old vs new values are.

## When to prefer this

Use this endpoint when you need to detect changes in DNS TXT records specifically as resolved by CleanBrowsing DNS (which applies content filtering), and want stateful change detection with before/after diffs rather than just a raw record lookup. Prefer it over plain DNS TXT lookups when you need to schedule monitoring, get alerted on changes, or audit a history of TXT record values. Choose CleanBrowsing specifically when you want to understand how a filtered DNS resolver sees the domain's TXT records.

## Known failure modes

- Domain not found or non-existent — returns NXDOMAIN or empty record set
- CleanBrowsing resolver unavailable — upstream DNS error returned
- No previous check stored (first call) — 'changed' is false or undefined, no diff available
- Domain input missing or malformed — request rejected
- Result cache expired (older than 90 days) — treated as first check, no diff available

## How this service works

Change watch for dns txt via cleanbrowsing: 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 DNS TXT record answer as seen by CleanBrowsing DNS, a boolean 'changed' flag indicating whether the result differs from the previous check (stored up to 90 days), a field-level diff showing before and after values for any changed fields, and a timestamp of when the record was last seen in this state.
