# DNS CAA Records Change Watch

> DNS CAA 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 CAA records for a domain and returns whether they changed since the last check, with before/after field diffs and timestamps.

## 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-caa-records-change-watch-f9bb1991
```

Example prompt: Keep an eye on the DNS CAA records for example.com and let me know if anything changes — compare today's lookup against the last snapshot and show me exactly which fields are different and what the old vs new values are.

## When to prefer this

Choose this endpoint when you need to detect changes in DNS CAA records over time on a scheduled basis, rather than just performing a one-time lookup. It is ideal for security monitoring, compliance auditing, or post-migration verification where knowing what specifically changed (field-level diffs with before/after values) is more valuable than just retrieving current records. Prefer it over a raw DNS lookup tool when historical comparison and change detection are the primary goals.

## Known failure modes

- Domain not found or invalid domain name — returns DNS resolution error
- No previous snapshot exists (first call) — returns current records with changed=false or no diff
- Domain has no CAA records — returns empty CAA record set
- Network or upstream DNS resolver error — may return timeout or unavailable error
- Stored snapshot expired (older than 90 days) — treated as first call, no diff available

## How this service works

Change watch for dns caa 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 caa record lookup changes. $0.01 per check.

## Output

Returns the current DNS CAA record lookup result, a boolean 'changed' flag indicating whether records differ from the previous call, a list of exactly which fields changed with before/after values, and the timestamp of when the records were last seen. Previous results are retained for 90 days for comparison.
