As a registered user you can upload any CSV file containing a first name column. For a better determination result, you can optionally add a country column to your dataset. While it is not necessary to specifically name the columns, our assistant guides you through the process by letting you choose which column contains which token, first name or country included. The feature is located within your account. Processed records will be charged like requests so that you can upload a CSV file with up to 500 entries for free every month. The CSV bulk upload requires a Gender-API.com account.
