# NetIntel Email Intelligence Analyzer

> NetIntel Email Intelligence Analyzer is a paid API for AI agents from netintel.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Analyzes an email address to assess deliverability, validity, format, MX records, and risk signals like disposable/role-based/free-provider classification, returning a graded score.

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 netintel-email-intelligence-analyzer-42e783b7
```

Example prompt: Can you analyze the email john@acmecorp.com and tell me if it's actually deliverable, whether it's a business address, and flag it if it looks like a disposable or role-based account?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-signal email quality assessment — not just format checking — covering deliverability, MX records, disposable domain detection, role-based classification, and business vs personal distinction in a single graded response. Prefer it over simple regex-based validators or single-signal checks when onboarding users, cleaning lead lists, or gating signups.

## Known failure modes

- Missing or malformed email query parameter returns 400/validation error
- Email domain has no MX records — mx_records_found will be false and deliverability may be 'undeliverable'
- Disposable domain database may lag newly created throwaway providers
- Network timeout if MX DNS lookup takes too long
- Payment failure (402) if USDC balance is insufficient for $0.05 per-call fee

## How this service works

Email verification & deliverability check (email validator / verifier) — validate an address, detect disposable/temporary domains, flag role-based inboxes, confirm MX records exist, and return a trust/risk 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, local part, domain, format validity boolean, MX records array, MX records found boolean, deliverability string (e.g. 'deliverable'), is_disposable boolean, is_role_based boolean, is_free_provider boolean, is_business_email boolean, a list of findings, a numeric score (0-100), and a letter grade (e.g. 'A').
