Fixer API uses API keys to authenticate requests. You can view and manage your API keys in the Accounts page.

Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

All requests made to the API must hold a custom HTTP header named "apikey". Implementation differs with each programming language. Below are some samples.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
