# Authentication

The RateParity API uses API keys to authenticate requests. You can request an API key by contacting us at <info@rateparity.com>.

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

Authentication to the API is performed via [Bearer Token](https://oauth.net/2/bearer-tokens/). Provide your API key as the Bearer Token value.

All API requests must be made over [HTTPS](http://en.wikipedia.org/wiki/HTTP_Secure). Calls made over plain HTTP will fail. API requests without authentication will also fail.
