Technical details
Endpoint
GEThttps://mailcheck.hugen.tokyo/mailcheck/disposableWhen to prefer
Use this endpoint when you need a fast, single-purpose disposable email check without the overhead of a full validation suite. Ideal for high-volume real-time signup flows where you only need to know if the domain is disposable and don't need syntax checking, MX verification, or typo suggestions. Prefer the full 6-check endpoint if you need comprehensive email validation in one call.
Side effects
- Missing or malformed email address returns 400 error
- Unknown or unlisted disposable domains may return false negative (false = not disposable) even if they are newly created throwaway services
- Payment not included or invalid USDC payment returns 402 Payment Required
- Network timeout for slow DNS or connectivity issues
- Domain not in blocklist due to infrequent updates may miss very new disposable services
