## 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 verifypulse-dmarc-compliance-check-da638c13
```

Example prompt: Can you check if vercel.com is DMARC compliant and has a valid SPF record before I send our next email campaign to contacts there?

## When to prefer this

Use this endpoint when you need a fast, real-time check of a specific domain's DMARC and SPF compliance status before sending email, auditing senders, or verifying inbound email legitimacy. Prefer this over full email address verification endpoints when only domain-level DNS security posture is needed.

## Known failure modes

- Domain does not exist — DNS lookup fails, may return non-compliant or error response
- Domain has no MX records — SPF/DMARC may be absent, returns spf_valid: false
- Malformed domain input — API may return validation error
- Temporary DNS resolution failure — transient errors possible for live DNS queries
- Domain with no DMARC record — returns compliant: false with dmarc_policy absent or null

## How this service works

VerifyPulse is a high-speed B2B email verification engine. Validate RFC syntax, resolve live DNS MX records, filter 3,800+ disposable domains, and run simulated SMTP handshakes in sub-140ms. Stop bounces before sending.

## Output

Returns a JSON object with the queried domain, a boolean 'compliant' flag indicating overall DMARC compliance, a boolean 'spf_valid' flag, and the DMARC policy string (e.g. 'reject', 'quarantine', 'none').
