Agify.io

API

Free API to estimate age from a first name

Overview

Agify.io offers a RESTful API that estimates a person’s age using a given first name. The primary endpoint accepts GET requests with a 'name' parameter (e.g., /?name=john) and optional 'country_id' to refine results by region. Responses are in JSON format, including fields like estimated age, data point count, and input name. Ideal use cases include user profiling in apps, demographic analysis for marketing tools, form auto-filling, and personalized content delivery based on estimated age demographics.
