Use the National Nutrient Database API to access USDA data on food nutrients. The REST API returns responses in JSON or XML and requires an API Key. Calls to the API are limited to 1,000 per hour, but the data is free and open to the public for use. Use the National Nutrient Database to generate nutrient reports, get lists of products by nutrient or food group, or search for a specific food product.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.
