Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

const url = "https://api.genderize.io?name=alice";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://api.genderize.io?name=alice"
headers = {}

response = requests.get(url, headers=headers, timeout=30)
response.raise_for_status()
data = response.json()
print(data)

curl "https://api.genderize.io?name=alice"

What Can You Build?

// Get repository or project information
const response = await fetch(`https://genderize.io`);
const data = await response.json();
console.log('Project info:', data);
const info = data.repository || data;
console.log('Name:', info.name || info.full_name);
console.log('Stars:', info.stars || info.stargazers_count || 'N/A');

// Fetch developer resources
const response = await fetch(`https://genderize.io`);
const data = await response.json();
const items = Array.isArray(data) ? data : data.results || data.items || [data];
items.slice(0, 5).forEach(item => {
  console.log(`📦 ${item.name || item.title}: ${item.description || 'No description'}`);
});

// Search for development resources
const query = 'javascript';
const response = await fetch(`https://genderize.io`);
const data = await response.json();
const results = data.items || data.results || [];
results.slice(0, 5).forEach(r => {
  console.log(`Result: ${r.name || r.title} - ${r.url || r.html_url || ''}`);
});

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

Common Errors & Troubleshooting
