# Nutritionix API Guide

The Nutritionix API v2 is geared towards making it as easy as possible for a user to track calories they consume while eating, and calories they expend while exercising.

The Nutritionix Track API powers the [Nutritionix Track mobile app](https://www.nutritionix.com/app). We recommend checking out the Nutritionix Track app to see our recommended best practices for API implementation.

| Natural Language for Nutrients (v2/natural/nutrients) | Parse natural language requests like "1 cup flour, 1 pinch of salt, and 1 cup butter", or use in combination with the /v2/search/instant endpoint to provide nutrition information for common foods. See [live demo here](https://www.nutritionix.com/natural-demo?q=1%20cup%20mashed%20potatoes%20and%202%20tbsp%20gravy&s=1). |
| Instant Endpoint (v2/search/instant) | Provides fast results for autocomplete text box interfaces. |
