How this service works
MCP server with 49 developer tools + 300+ REST APIs — agent memory, QR codes, passwords, AI text, finance, health, crypto, weather, and more. Free tier, no API key needed.
Output
Returns a JSON object with an 'ok' boolean indicating whether the email address passed verification. May include additional fields about validity, format correctness, and deliverability status depending on the service tier.
Example use cases
Pre-signup email validation
“Before I create an account for this user, check if their email address user@somedomain.net is actually valid and deliverable.”
Cleaning marketing contact list
“I have a lead I want to email — can you verify that sales@prospectcompany.com is a legitimate email address so I don't waste the send?”
Catching typos in form submissions
“A user just submitted the email adress johndoe@gmial.com on our contact form — can you check if that's a valid email or if they made a typo?”
Technical details
Endpoint
GEThttps://api.gadgethumans.com/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.002 per call) email verification without needing to manage a dedicated email validation service subscription. Ideal for lightweight integrations, ad-hoc checks, or agents that need occasional email validation as part of a broader workflow. Best suited for single-address verification rather than bulk list cleaning.
Side effects
- Missing or empty email parameter — returns validation error
- Malformed email format — may return invalid status rather than an error
- Network timeout if mail server lookup takes too long
- Rate limiting on free tier for high-volume checks
- Disposable or temporary email domains may return inconsistent results
