About

Agify predicts how old someone with a given first name is likely to be, based on name statistics (for example, "Agnes" skews older than "Aiden"). It's run by Demografix and now requires a free API key, which is quick to get with just an email. One free key also works for its sister services: Genderize.io (guesses gender from a name) and Nationalize.io (guesses nationality from a name).

Details

Free to start. You may need a free key, but no credit card.
