Submit an email address to evaluate the positive age signal returned by the API.

How the signal should be used

A positive control, not a standalone verdict

Minimum observed age

A matched record means the address was seen no later than the returned year. The demo converts that year into a conservative minimum age.

Domain classification Beta

Mainstream, privacy relay, disposable, suspicious, and unknown classifications add context without replacing your fraud model.

Clear null state

No match means no established-age signal was found. It should not be interpreted as proof that an email is abusive.

API shape

One endpoint for an email intelligence check

The API returns a normalized address, whether it was found, the earliest observed year when available, and a lightweight beta classification for the domain.
