The Abstract Gender API is a simple application programming interface (API) that allows any individual, company, non-profit, or other organization to determine gender of a first name. Unlike other more complex data sources, this API is very straightforward to use but provides a fast response in accurate data. Only an individual’s name needs to be submitted and the best guess at a gender as well as a confidence score will be returned by the API. More detailed and complex functionality, such as seeing gender and confidence breakdowns by name and country, are available for an additional charge.
