Perfect for formatting headings, names, or titles — transforms "hello world example" into "Hello World Example". Handles Unicode characters and preserves spacing.

});
const data = await response.json();
console.log(data);import requests
response = requests.get('https://tinyfn.io/v1/string/capitalize',
