Predict Age From a Name - Accurate Age Inference API

# Agify.io > Agify.io is a REST API that predicts the age of a person from their name, returning an estimated age and the number of data rows examined. It is operated by Demografix ApS (Denmark) and is part of a suite of three name-based demographic APIs. Agify.io bases its predictions on a dataset of over 908 million data rows covering 240+ countries and territories. The API is used for demographic analysis, audience segmentation, customer profiling, and academic research. Important: Agify.io predicts the statistical average age of people with a given name — it does not predict the age of a specific individual. Results reflect the age distribution of people with that name in the dataset, not a birth year estimate for any particular person. ## Documentation - [Documentation Hub](https://agify.io/documentation): Overview of all integration surfaces — API, MCP server, spreadsheet tool, and no-code workflows ## API - [API Reference](https://agify.io/documentation/api/reference): Full API reference with request/response formats, parameters, error codes, and examples - [Name handling](https://agify.io/documentation#name-handling): Send a first name or a full name; age is predicted from the given name, and the surrounding name identifies which part that is, so there is no need to split full names. Titles, initials, and accents are handled. - [Example request](https://api.agify.io?name=peter): `GET https://api.agify.io?name=peter` returns `{"count":175919,"name":"peter","age":61}` - [Country-scoped request](https://api.agify.io?name=peter&country_id=dk): `GET https://api.agify.io?name=peter&country_id=dk` returns `{"count":3086,"name":"peter","age":55,"country_id":"DK"}` — age predictions vary by country because naming trends differ. Use `country_id` (ISO 3166-1 alpha-2) to scope predictions. - [Batch requests](https://agify.io/documentation): Up to 10 names per request using `name[]=` parameter. Each name counts as one lookup against your quota. ## Pricing
