# API

The BlueGamma API gives you programmatic access to real-time interest rate data, including forward curves, swap rates, discount factors and more.

{% hint style="info" %}
The curves returned by the API are **not** the same as the curves shown on the public [bluegamma.io](https://www.bluegamma.io) marketing pages. See [Public Website Curves vs. Platform Curves](/documentation/methodology/public-website-curves-vs-platform-curves.md) for details.
{% endhint %}
