# DNS TXT Records Change Watch

> DNS TXT Records Change Watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors DNS TXT records for a domain and returns whether they changed compared to the previous check, with before/after field diffs.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-records-change-watch-fa6bfaac
```

Example prompt: Keep an eye on the DNS TXT records for example.com and let me know if anything has changed since the last time you checked — especially SPF or DKIM entries.

## When to prefer this

Choose this endpoint when you need to detect changes to DNS TXT records over time on a scheduled or on-demand basis, rather than just fetching current records. It is specifically useful for monitoring SPF, DKIM, DMARC, domain verification tokens, and other TXT records for unauthorized modifications or configuration drift, with built-in diffing and 90-day history retention.

## Known failure modes

- Domain not found or invalid — returns error with no records
- First-time call for a domain has no previous snapshot to compare against, so 'changed' may be indeterminate
- DNS propagation delays may cause transient differences
- Rate limiting or payment failure may prevent the check from running
- Records may be temporarily unavailable due to DNS resolver outages

## How this service works

Change watch for dns txt records: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when dns txt record lookup changes. $0.01 per check.

## Output

Returns the current DNS TXT records for the domain, a boolean 'changed' flag, a field-level diff showing exactly which records were added, removed, or modified with before/after values, and a timestamp of when the records were last seen. The previous result is retained for 90 days for comparison.
