description: >-
  Agify.io is a free REST API that predicts the age of a person based on their
  first name using statistical data from over one billion records spanning 195+
  countries. The service is provided by Demografix ApS and shares a single API
  key with the companion Genderize.io and Nationalize.io APIs. The free tier
  allows 2,500 name lookups per month with no credit card required; paid plans
  scale up to 250,000+ names per month. Requests support batch processing of
  up to 10 names and optional country scoping via ISO 3166-1 alpha-2 codes.
  The API is stateless, cookieless, and GDPR compliant — submitted names are
  discarded immediately and never stored.
