# Mail Health Report

> Mail Health Report is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Checks a domain's full email security posture (MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT, BIMI) and returns an A-F letter grade, numeric score, and actionable fixes.

## Facts

- Endpoint: GET https://intel.rallylive.ca/monitor/mail-health

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 mail-health-report-546ee053
```

Example prompt: Can you run a full email security health check on example.com and tell me the grade, score, and what needs to be fixed to improve it?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call email security audit covering all major standards (MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT, BIMI) with an overall grade and actionable fixes, rather than querying individual DNS record types separately. Ideal for pre-send deliverability checks, vendor due diligence, or generating IT remediation reports.

## Known failure modes

- Domain does not exist or is not resolvable — returns an error or empty results
- DNS lookup timeout for one or more record types may result in partial data
- DKIM selector detection is hint-based (common selectors only) and may miss custom selectors
- No input domain provided — API returns a validation error
- Rate limiting or payment failure returns 402 or 429 status

## How this service works

Mail health report with an A-F grade in one call: MX records present and resolvable, SPF present and syntactically sane (mechanism count, -all/~all), DMARC policy strength, DKIM selector hints (common selectors probed), MTA-STS and TLS-RPT presence, and BIMI. Returns the grade, score and concrete fixes. $0.01 per domain.

## Output

Returns a letter grade (A–F), a numeric score, and per-check results covering: MX records (presence and resolvability), SPF record (presence, mechanism count, -all/~all strictness), DMARC (policy strength: none/quarantine/reject), DKIM (hints from probing common selectors), MTA-STS presence, TLS-RPT presence, and BIMI record presence. Also includes concrete, actionable remediation recommendations for each failing or weak area.
