# NetIntel Email Verify

> NetIntel Email Verify is a paid API for AI agents from netintel.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Verify an email address via syntax check, MX record lookup, and disposable/role/free-provider detection, returning a boolean deliverability verdict with a machine-readable reason code.

## Facts

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-verify-161e05f9
```

Example prompt: Can you check whether user@github.com is a real, deliverable email address — specifically whether the domain has MX records, whether it's a disposable or role-based address, and whether it's safe to send to?

## When to prefer this

Use this endpoint when you need a fast, low-cost boolean gate (deliverable / safe_to_send) on an email address before sending, importing into a CRM, or creating an account — especially when you need disposable, role-based, and free-provider classification alongside MX validation. Prefer this over /email-intel/analyze when you need a simple yes/no decision rather than a scored trust report. Note that this performs DNS-level checks only and does not SMTP-probe the individual mailbox.

## Known failure modes

- Invalid or malformed email address returns format_valid: false with reason indicating syntax error
- Domain has no MX records — mx_found: false, result: undeliverable
- Address is on a known disposable provider list — disposable: true, result: risky or undeliverable
- Rate limiting or quota exceeded returns HTTP 429
- Domain DNS lookup timeout may cause delayed or failed MX resolution
- Individual mailbox existence is not confirmed — smtp_checked is always false; a deliverable result does not guarantee the specific mailbox accepts mail

## How this service works

Verify an email address before you send: syntax + MX + disposable/role/free-provider detection in one call, boolean-first (deliverable, safe_to_send) with a machine-readable reason. DNS-level check only — does not confirm the individual mailbox exists (no SMTP probe). For a scored trust report instead of a yes/no gate, see /email-intel/analyze.

## Output

A JSON object containing: the normalized email and domain, a result string (deliverable/risky/undeliverable), boolean flags for deliverable, safe_to_send, format_valid, mx_found, disposable, role_based, free_provider, and smtp_checked, a list of MX records found, a list of risk_flags describing issues, and a human-readable reason code summarizing the verdict.
