# SPF/DMARC Email Security Change Watch

> SPF/DMARC Email Security 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).

Runs an SPF/DMARC email security check for a domain, compares results against the previous call (retained 90 days), and returns what changed, which fields changed, and when the configuration was last seen.

## How to call it through Zero

```sh
zero fetch --capability spf-dmarc-email-security-change-watch-daaba59d
```

Example prompt: Keep an eye on the SPF and DMARC email security setup for example.com — check it on a schedule and let me know if anything changes compared to the last time you checked, including exactly what fields changed and what the old vs new values are.

## When to prefer this

Choose this endpoint when you need to detect changes in a domain's email security posture (SPF/DMARC) over time, rather than just a one-off audit. It is purpose-built for scheduled monitoring with built-in diffing and 90-day state retention, making it ideal for alerting workflows and compliance monitoring without maintaining your own comparison state.

## Known failure modes

- Domain not found or DNS lookup fails — returns error with no comparison data
- First call for a domain returns current result but no change comparison (no previous baseline)
- Domain has no SPF or DMARC records — returns empty/null fields for those records
- Previous result expired (older than 90 days) — treated as first call with no comparison
- Network timeout on DNS resolution — returns error or partial result

## How this service works

Change watch for spf dmarc 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 email security check for a domain changes. $0.01 per check.

## Output

Returns the current SPF/DMARC check result for the domain, a boolean 'changed' flag indicating whether the result differs from the previous call, a list of exactly which fields changed with their before and after values, and a timestamp of when the configuration was last seen. Previous results are retained for 90 days for comparison.
