The results from the 'instant' endpoint are separated into 2 arrays each with a maximum 20 food items:

  • branded: results from Nutritionix.com branded food database (restaurant brands and grocery brands).
  • common: results from Nutritionix.com common food database (curated list of averaged food items that are not brand-specific).

Example Usage

  • When you perform /search/instant/, the application displays the search drop-down based on the search criteria in the UI.

FAQs

How to filter search results based on their nutrients?

The /instant endpoint supports POST requests for filtering ranges of nutrients. For example, to filter items for matches with “burger” where calories (attr_id 208) is less than 500, you could submit a post query like this:

{
  "query": "burger",
  "full_nutrients": {
    "208": {
      "lte": 500
    }
  }
}
  • gte = greater than
  • lte = less than

How do you get nutrition information for foods in the /search/instant endpoint?

When you hit the /search/instant endpoint it returns two arrays: common and branded foods.

To get the nutrition information for common foods, take the food_name that is returned from any item in the "common" array, for example, "Big Mac" and POST that as the query to our /natural/nutrients endpoint.
nutritionix-faq

To get the nutrition information for branded foods take the value of the “nix_item_id” attribute from any of the objects in the “branded” array, for example, 513fc9e73fe3ffd40300109f, and hit the /search/item endpoint.

What are the recommended debounce metrics when hitting the /v2/search/instant endpoint?

There are two important steps to ensure you are hitting the /search/instant endpoint effectively.

  1. Requests to the /v2/search/instant endpoint should be debounced for at least 300ms. This will prevent an overload of requests to the endpoint as well as allow the client application some time before rendering the latest results.

  2. You should not send requests to the instant endpoint until the user types at least 3 characters. Sending queries to instant at 1-2 characters can cause a substantially higher number of API queries to be made.

How do I filter out duplicate common foods from the /search/instant endpoint?

To provide the best experience to the end user, it is recommended to filter common food results on "tag_id". Common foods with the same tag_id have identical nutrition (for example, "Blackberry" and "Blackberries"). For best results, filter the results to show only one food per tag_id. Generally, the first one will be the most relevant based on the user search query.
