How this service works
483,000+ pay-per-call data APIs and free tools built on official sources — finance, company & government data, FRED, Census, crypto, calculators. USDC on Base via x402, native MCP. No API key, no signup.
Output
Returns a validation result for the given email address, including whether the format is correct, whether the domain exists, and whether the mailbox is likely deliverable.
Example use cases
Pre-send email validation for campaigns
“Before we send out this batch of invitations, can you quickly verify that sarah.martinez@techcorp.com and michael.chen@innovate.io are real, deliverable email addresses? I don't want bounces eating into our sending quota.”
Lead quality check during enrichment
“I just got these three leads from the sales team — alex@startup-xyz.com, info@company-abc.net, and contact@enterprise-solutions.io. Can you validate which ones are actually active mailboxes before we spend time researching the companies?”
User signup email verification
“A new user just signed up with the email david.white@domain.example. Can you check if that address is real and actually deliverable before we send them our welcome email and activation link?”
