Kiprio Email Validate vs MailCheck.ai
One of Kiprio's focused developer APIs, this endpoint runs syntax, MX-record, disposable-domain, and role-account checks on an email address and returns a confidence score in one JSON response. A keyless demo tier is rate-limited to 20 requests a day; a free API key raises that ceiling before paid plans apply.
MailCheck.ai has rebranded to UserCheck, but its original keyless lookup endpoint keeps working unchanged: pass an address and get back disposable, free-provider, MX, and domain-age signals in one JSON response, aimed at blocking throwaway signups. The rebranded product adds a free-to-start paid tier for higher-volume, authenticated use.
