What does Gender Api do?
Gender Api is a specialized API that tells you whether a first name is more likely used by males or females. It takes a name (or an email address) and returns the predicted gender along with a confidence score. The service is powered by AI and a database of over 9 million names from 192 countries, making it far more accurate and faster than asking a generic large language model.
How does it work? You send a simple GET request with a name and your API key, and you get back a JSON response with the gender, number of samples, accuracy percentage, and response time. For example, querying "elizabeth" returns "female" with 100% accuracy. The API also handles country-specific variations — "Andrea" is male in Italy but female in other regions. You can batch multiple names in one call, analyze email addresses by extracting the first name, and even upload CSV files for bulk processing. Gender Api provides official client libraries for PHP, TypeScript, JavaScript, Python, R, Java, C#, Go, Ruby, PowerShell, and Rust, so integration is straightforward.
This tool is most useful for developers who need to enrich user data, marketers personalizing campaigns, and analysts studying demographic trends. It's a no-fuss, reliable service that does one thing well: gender detection. If you need to sort a mailing list, tailor content, or just understand your audience better, Gender Api gives you a quick, data-backed answer without the overhead of running your own model.
