# DMARC Record Change Watch

> DMARC Record 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 a domain's DMARC DNS record on a schedule, returning the current result, whether it changed, which fields changed with before/after values, and when it was last checked.

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 dmarc-record-change-watch-f0c22643
```

Example prompt: Keep an eye on the DMARC record for example.com and let me know if anything changes — I want to see exactly which fields were different and what they changed from and to.

## When to prefer this

Choose this endpoint when you need to detect changes in a domain's DMARC configuration over time rather than just fetching the current record once. It is ideal for scheduled monitoring pipelines, compliance alerting, or verifying that DMARC policy updates have propagated correctly. Prefer it over a one-shot DMARC lookup when the goal is change detection with field-level before/after diffs.

## Known failure modes

- Domain not found or does not have a DMARC record — returns current state with no diff
- No previous result stored (first call or older than 90 days) — returns current result with changed=false or null diff
- Invalid domain input — may return error or empty result
- Network/DNS lookup failure for the target domain — transient error response

## How this service works

Change watch for dmarc record check: 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 dmarc record check for a domain changes. $0.01 per check.

## Output

Returns the current DMARC record check result, a boolean 'changed' field indicating if anything differs from the previous call (stored up to 90 days), a detailed diff of exactly which fields changed with before and after values, and the timestamp of when the record was last seen.
