How this service works
Verify email syntax and public DNS readiness with a bounded deterministic preflight. Forest checks normalized syntax, MX/address records including explicit null MX, and curated role/free/disposable-domain signals, then returns a conservative safe-to-attempt decision. It never connects to SMTP, sends mail, authenticates, stores customer mailboxes or claims that a mailbox exists. Base mainnet USDC
Output
Returns a structured object with: normalized email, syntax validity flag, MX/address record presence, explicit null-MX detection, role-address signal, free-domain signal, disposable-domain signal, and a conservative boolean safe-to-attempt decision. Does not confirm mailbox existence or perform SMTP probing.
Example use cases
Scrub leads before email campaign
“We have a new signup — alex@guerrillamail.com — can you validate that email address and tell me if it's safe to attempt delivery, and whether it's a disposable or free-provider domain?”
Block fake emails at registration
“A user just signed up with postmaster@example.com — run a preflight check on that email to see if the syntax is valid, the domain has working MX records, and whether it's a role address we should reject.”
Enrich CRM contact data
“I'm cleaning our CRM and want to check whether support@freeemailservice.net is a legitimate deliverable address — verify the syntax, DNS readiness, and flag if it's a free or disposable domain.”
Technical details
Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/email/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, privacy-safe email preflight that stops short of SMTP probing — ideal for validating user-submitted emails at signup, scrubbing lead lists, or gating outreach without risking mail server reputation. Prefer it over full SMTP verification when you want zero side effects and no mailbox-existence claims.
Side effects
- Invalid or malformed JSON input returns a 400 error
- Email exceeding 320 characters is rejected
- DNS lookup timeouts may result in inconclusive MX record results
- Payment failure (x402) if USDC balance is insufficient
- Domain may have valid MX records but still be a disposable provider if not in curated list
