How this service works

Output
Returns a JSON object with the original email, a boolean validity flag, the domain portion, whether the domain is disposable (checked against 5,361 known domains), whether MX records exist, whether it's a role-based address (35 patterns), and a deliverability assessment. May include a typo suggestion when the domain resembles a common provider.
Example use cases
Signup form email screening
“Before we add this user to our system, check if 'noreply@mailinator.com' is a legitimate email — I want to know if it's disposable, has valid MX records, and whether it's a role address we should reject.”
Catching email typos at checkout
“A customer just entered 'sarah@gmial.com' — can you validate it and tell me if there's a typo in the domain so we can suggest the correct address before they finish checkout?”
Lead list email quality check
“I have a lead's email 'info@acmecorp.com' — run it through email validation and tell me if it's a role-based address, whether MX records exist, and if it's likely to be deliverable.”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/email-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive email validation beyond simple regex — especially when you want disposable domain detection (5,361 domains), role-address filtering, MX record verification, and typo correction for common providers all in a single call. Ideal for signup flows, lead qualification, and data hygiene pipelines where deliverability confidence matters.
Side effects
- Missing required 'email' parameter returns an error
- Malformed or unparseable email string may return valid:false with no further details
- MX lookup may time out for obscure or slow DNS servers
- Disposable domain list may not cover very recently created throwaway services
- Network errors result in HTTP 5xx responses
