Depending on your API version or the integration you're using, our endpoints will either return an accuracy or a probability value in the response. The accuracy parameter returns how sure we are that this name is either male or female. The value is calculated by the number of records in our database. For example, if we have 100 samples of a name, 96 are female, and 4 are male, the accuracy is 96% (or a .96 probability). A low accuracy indicates that this name is probably used by multiple genders and cannot be conjugated to a specific gender.
