# ForgeMesh Email Validator

> ForgeMesh Email Validator is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Validates an email address via RFC-style syntax check and live DNS MX/A record lookup, returning the parsed domain, sorted mail hosts, and a deliverable flag — without probing the mailbox itself.

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 forgemesh-email-validator-8dca947c -d '<json body>'
```

Example prompt: Can you check whether john.smith@acmecorp.com is a deliverable email address — specifically whether the domain actually has mail servers set up to receive it?

## When to prefer this

Use this endpoint when you need fast, low-cost email domain reachability checks — e.g. lead cleaning, signup form validation, or contact list hygiene — and you only need to confirm the domain has mail servers, not that a specific mailbox exists. Prefer this over heavier SMTP-probing validators when privacy, speed, and cost matter.

## Known failure modes

- Malformed email input returns a syntax error or invalid flag
- Domain has no MX or A records — deliverable flag returns false
- DNS timeout or transient lookup failure may return an error or inconclusive result
- Non-existent TLD results in DNS NXDOMAIN and deliverable false
- Payment failure (x402) returns 402 before any validation occurs

## How this service works

Check whether an email address is well-formed and its domain can actually receive mail — RFC-style syntax check plus a live MX (falling back to A) lookup — returning the parsed domain, sorted mail hosts, and a deliverable flag. Answers "is this email address real" and "will mail sent here bounce" without probing the mailbox itself. Use for lead cleaning, signup validation, and contact verification. Nothing stored.

## Output

Returns the parsed domain from the email, a list of mail hosts sorted by MX priority (with A-record fallback), and a boolean deliverable flag indicating whether the domain accepts mail. Does not confirm individual mailbox existence.
