## 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 agent-tools-full-email-risk-check-647d115e
```

Example prompt: Can you do a full email risk check on jane@acme.com — I need the risk score, verdict, and domain health details like SPF, DMARC, and how old the domain is?

## When to prefer this

Choose this endpoint when you need a single comprehensive email risk signal that combines deliverability, disposable detection, AND domain health (age, SPF, DMARC, registrar, website) into one scored verdict. Prefer it over the basic email_check endpoint when fraud screening, lead qualification, or signup gating requires domain-level trustworthiness signals beyond just syntax and MX records.

## Known failure modes

- Invalid or malformed email address returns a validation error
- Domain does not exist or has no DNS records causing domain health lookup to partially fail
- Network timeout when checking website reachability for the sender domain
- Missing required query parameter 'email' results in a 400 bad request
- Payment failure (x402) if USDC balance is insufficient

## How this service works

One call email risk check: everything in email_check plus sender domain health (domain age, registrar, SPF, DMARC, website reachable) and a 0-100 risk score with accept/review/reject verdict. Use for fraud screening, lead qualification and signup gating.

## Output

Returns a JSON object with the email address, a verdict of accept/review/reject, a 0-100 risk score, an array of risk reasons, a disposable flag, a has_mail_server flag, and a domain_health object containing SPF record, DMARC record, domain age in days, registrar name, and whether the website is reachable.
