# Email Deliverability Report Change Watch

> Email Deliverability Report 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 email deliverability and authentication check for a domain, compares it to the previous result (stored 90 days), and returns what changed, when, and the current values.

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 email-deliverability-report-change-watch-b596858c
```

Example prompt: Keep an eye on email deliverability for example.com and let me know if anything changes — things like SPF, DKIM, DMARC, or MX records — compared to the last time you checked.

## When to prefer this

Choose this endpoint when you want to be notified of changes to a domain's email deliverability and authentication configuration over time, rather than just fetching the current state. It is ideal for scheduled agent workflows that need to detect drift in SPF, DKIM, DMARC, or MX records without having to store and diff results yourself. Prefer it over a one-shot deliverability check when change detection and audit trails matter.

## Known failure modes

- No previous result exists for the domain (first call returns current report with changed=false or no diff)
- Domain does not exist or has no DNS records (may return empty or error report)
- Payment not processed correctly (x402 payment required error)
- Network or upstream DNS lookup failure causing incomplete report
- Results older than 90 days are purged, resetting the comparison baseline

## How this service works

Change watch for email deliverability report: 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 authentication and deliverability report for a domain in one call changes. $0.01 per check.

## Output

Returns the current email deliverability report for the domain, a boolean `changed` flag indicating whether it differs from the last stored result, an exact list of which fields changed with before and after values, and the timestamp of when the previous result was last seen. Previous results are retained for 90 days.
