How this service works
All-in-one API hub: Social Media, Jobs, Finance, Crypto, and Tools. Pay-per-call with x402 protocol on Base chain.
Output
Returns a structured validation result for the submitted email address, typically including whether the format is valid, whether the domain exists and has mail exchange records, whether the address is deliverable, and whether it belongs to a known disposable email provider.
Example use cases
Pre-registration email screening
“Before creating the account, check whether the email address sarah.jones@gmail.com is a real, deliverable address and not a throwaway or fake one.”
Bulk lead list cleanup
“I have a lead I need to verify — can you check if marketing@techstartup.io is a legitimate, deliverable email address before we reach out?”
Detecting disposable email signups
“A user just signed up with the email temp123@mailinator.com — can you check if this is a disposable or fake email address that I should reject?”

Choose this endpoint when you need a quick, pay-per-call email validation without a subscription, especially in workflows on the Base blockchain using the x402 payment protocol. It is well-suited for single-address spot checks during user registration, lead qualification, or form submission validation where you want to avoid committing to a monthly SaaS plan.
Side effects
- Invalid or missing email address in request body returns a 400 error
- Network or DNS lookup failure may result in inconclusive deliverability check
- Payment not provided or insufficient USDC balance triggers 402 payment required
- Rate limiting or server-side errors return 5xx responses
- Newly registered domains may not yet resolve, causing false negatives
