Agify

Predicts age from a first name. Weirdly useful for demos.

Agify estimates a person’s age from their first name using aggregated census-style data. It is the canonical “my first fetch()” API: no key, instant JSON, CORS everywhere. Free tier covers 100 names a day; the paid tier is rarely needed outside batch jobs.
