If you can provide a country code or specific territory in your query, we can guarantee a significant improve in detecting the right gender. For example: While Andrea is male in Italy, Andrea is a female name in Germany and can even be both in the US. In this case, we provide an accuracy value in the query result, ranging between 0 and 100. It tells you how certain we are in having detected the right gender. If you think the value is too low, you can still ask your user to provide the right gender themselves. In most countries, however, we can determine the correct gender in over 94% of cases.
