Agify.io is a simple REST API that predicts the age of a person based on their first name. Using a large dataset of name-age associations, it returns an estimated age along with a count of how many data points were used and the name's country-localized variant when a country code is provided. Supports batch requests for up to 10 names per call. Used for demographics research, content personalization, and marketing segmentation.
