Analyzes an email address for risk signals including syntax validity, domain checks, MX/SPF/DMARC records, disposable domain detection, and role-account identification.

## 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-vending-email-risk-analysis-66b96f5e -d '<json body>'
```

Example prompt: Can you run a full risk check on the email address 'john.doe@tempmail.org' — I want to know if it's disposable, whether the domain has valid MX and SPF/DMARC records, and if it looks like a role account?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal email risk assessment in a single call — covering syntax, DNS infrastructure (MX, SPF, DMARC), disposable domain detection, and role-account classification. It is ideal for agent-driven onboarding flows, fraud screening, or outreach validation where you need structured, machine-readable risk data rather than a simple boolean valid/invalid check.

## Known failure modes

- Invalid or malformed email string returns a syntax error or validation failure
- Non-existent domain with no DNS records may result in failed MX/SPF lookups
- Timeout or connectivity issues reaching DNS resolvers may yield incomplete signals
- Very new domains may not yet have SPF/DMARC records, producing false negatives
- Private or internal email domains may not resolve from public DNS

## How this service works

Pay-per-call machine utilities for autonomous agents.

## Output

Returns structured machine-readable risk indicators for the submitted email address, including: syntax validity assessment, domain existence and MX record status, SPF and DMARC policy presence, a flag for whether the domain is a known disposable/temporary email provider, and a flag for whether the local part is a generic role account (e.g. info@, admin@, support@).
