# NetIntel Email Intelligence Analyzer

## 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 netintel-production-440c-up-railway-app-0bcc7870
```

Example prompt: Can you check whether j.smith@acme-corp.com is a real, deliverable business email — is it disposable, role-based, and does it have valid MX records?

## When to prefer this

Use this endpoint when you need a comprehensive single-call email quality assessment — combining format validation, MX/DNS checks, disposable domain detection, role-address detection, and a composite trust score — without sending a verification email. Prefer this over a simple regex check when gating signups, qualifying leads, or cleaning marketing lists where deliverability and sender reputation matter.

## Known failure modes

- Missing or malformed email parameter returns a 400-level error
- Domain has no MX records — mx_records_found returns false and deliverability is likely 'undeliverable'
- Disposable domain database may not include newly created throwaway domains
- Network timeout when performing real-time DNS/MX lookups for obscure TLDs
- Payment not authorized — 402 response if x402 payment header is missing or insufficient

## How this service works

Validate an email address for deliverability, detect disposable/temporary domains, identify role-based addresses, verify MX records exist, and return a trust score — so agents can qualify leads, clean lists, and gate signups without sending a single email.

## Output

Returns a JSON object with the original email, a letter grade (e.g. A–F), a numeric trust score (0–100), the domain and local part, deliverability status (deliverable/risky/undeliverable), boolean flags for disposable/role-based/free-provider/business-email/format-valid/mx-records-found, the actual MX record list, and an array of human-readable findings describing any issues detected.
