ForgeMesh Email Validator
x402
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.

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.
Example use cases
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?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/email-validateWhen to prefer
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.
Side effects
- 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
