How this service works
Email validation — syntax check plus live MX record DNS lookup to confirm deliverability.
Output
Returns a JSON object with the original email, a boolean 'valid' flag, the parsed domain, whether MX records were found (mx_found), and whether the syntax is correct (syntax_ok).
Example use cases
Bulk user signup email verification
“I'm getting a batch of new user signups from a form — can you validate each email address to make sure they're real and actually have mail servers configured before we add them to our system?”
Bounce prevention in outreach campaigns
“Before we send out our marketing emails tomorrow, can you check all the recipient addresses in our list to verify they're valid and actually set up to receive mail?”
Lead quality filtering in sales pipeline
“We just got a list of leads from our partner — can you validate which email addresses are real and deliverable so we know which ones are worth following up on?”
Technical details
Endpoint
GEThttps://agents.ai-rook.com/api/email-validateWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call email validation with no API key or signup, paying $0.002 USDC per check. Ideal for AI agents that need to verify email deliverability on-the-fly without maintaining a subscription. Choose this over heavyweight validation services when you need MX record checking plus syntax validation in a single call via x402 micropayment on Base.
Side effects
- Invalid or malformed email input returns syntax_ok false
- Non-existent domain returns mx_found false and valid false
- Network timeout when looking up MX records
- Payment failure via x402 if USDC balance is insufficient on Base mainnet
- Rate limiting or blocked requests if called too rapidly
