Integration Guide
Review the API Documentation
Visit the official Agify.io documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.
No Authentication Required
Good news — Agify.io does not require any authentication. You can start making API requests directly without registering for an API key or setting up OAuth credentials.
Use HTTPS for Secure Requests
Agify.io supports HTTPS, ensuring encrypted communication. Always use HTTPS endpoints in production to protect data in transit and comply with modern web security standards.
CORS Enabled — Direct Browser Access
Agify.io has CORS enabled, meaning you can make requests directly from the browser. This is ideal for frontend-only applications built with React, Vue, or vanilla JavaScript.
Implement and Test
Write your API integration code, start with a simple test request to verify connectivity. Implement proper error handling for network failures, rate limits, and invalid responses. Monitor your API usage to stay within any limits.
Code Examples
JavaScript / Fetch API:
// JavaScript example
fetch("https://agify.io")
.then(response => {
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
return response.json();
})
.then(data => {
console.log("API response:", data);
})
.catch(error => {
console.error("Error fetching from Agify.io:", error);
});Python / Requests:
# Python example
import requests
response = requests.get("https://agify.io")
if response.status_code == 200:
data = response.json()
print("API response:", data)
else:
print(f"Error: {response.status_code}")Frequently Asked Questions

Editor's Notes & Deep Dive
Key Features
- →GET /?name=alex returns predicted age plus a confidence count
- →GET /?name=alex&country_id=US biases prediction by country
- →Batch: GET /?name[]=alex&name[]=maria returns up to 100 in one call
Rate Limits & Quotas
Free tier: 1000 req/day, no key required. Higher limits require a paid plan.
Known Issues & Pitfalls
- !Accuracy is country-dependent; some countries have noisier name-age distributions
- !Rare names return count=0 and age=null — always handle that branch
- !Names are case-insensitive but non-Latin scripts may be rejected
How It Compares
Sibling to genderize-io. Both are made by the same team and have the same free-tier limits. Combine for age + gender prediction.
Sample Response
{
"name": "alex",
"age": 32,
"count": 12345
}Pro Tips
- ✓Use batched ?name[]=... to stretch the daily quota — 1 call can cover 100 names
