READ API Documentation

Downloading static data

It is recommended to use the live API to get fresh data about products, the minute they are uploaded to the database. However, in some cases, you may need a snapshot. They are available at:

CSV API

The character that separates fields is <tab> (tabulation).

Encoding

The file encoding is Unicode UTF-8.

MongoDB dump

Field reference

The fields used in the api. https://world.openfoodfacts.org/data/data-fields.txt

JSON interface

Pagination of results

If you're looking for all products within a facet (eg: https://fr-en.openfoodfacts.org/category/pizzas.json), you'll only have the 1st page. To move from page to page: 

https://fr-en.openfoodfacts.org/category/pizzas/1.json
https://fr-en.openfoodfacts.org/category/pizzas/2.json

Countries and Language of the Response

You can either use the global (https://world.openfoodfacts.org, https://ssl-api.openfoodfacts.org) or local (https://fr.openfoodfacts.org,https://en.openfoodfacts.org…) domains for your API queries

A few things to note

Country code (cc) and Language of the interface (lc)

By default, the country code (cc) and language of the interface (lc) are set through the subdomain.

Examples
  1. https://world.openfoodfacts.org --> cc = world, lc = en (default language for the "country")
  2. https://fr.openfoodfacts.org --> cc = fr (France), lc = fr (French)
  3. https://jp.openfoodfacts.org --> cc = jp (Japan), lc = ja (Japanese)
  4. https://ch.openfoodfacts.org --> cc = ch (Switzerland), lc = de (German, set as main language for Switzerland)
  5. https://ch-fr.openfoodfacts.org --> cc = ch, lc = fr (French)

Over-riding Country code (cc) and Language of the interface (lc) using cc and lc parameters

If you pass ?cc=us and/or &lc=it, it will set the country to US and the language to Italian -> if you just pass cc, the lc will be the one set in the subdomain. e.g. world.openfoodfacts.org + cc = fr --> cc = fr, lc = en (default language of world)

The cc affects which results are returned. cc = fr -> you get only products with France listed in the countries where sold field.

The lc affects the language in which results will come back.

If the results include links to products, those links will use a new subdomain that corresponds to the overrides.

Reading a product

The requested subdomain will be the locale fetched. (fr.openfoodfacts will fetch FR, world.openfoodfacts EN, world-fr FR products from the whole world)

Structure of the call

The final number must be a valid barcode.

Status codes

If a product is not found
{  
   "status_verbose":"product not found",
   "code":"32421",
   "status":0
}
If the product is found properly

See a full example: API/Full JSON example

Product images

  • Images ensure the reliability of Open Food Facts data. It provides a primary source and proof of all the structured data. You may therefore want to display it along the structured information.
  • We encourage you to let your users upload images for products that don't exist yet, and for existing products as well (packaging and information changes over time).
  • We have different scales of images. Use them wisely to save bandwidth, both for your users and Open Food Facts.
Raw images
  • image_small_url
  • image_thumb_url
  • image_url
Front image
  • "image_front_url"

Hierarchy

The categories_hierarchy is sorted by the "level" of each category. Level 0 means the category has no children, level 1 means it has children that do not have other children, level 2 is when it has children that have children that do not have children etc.

Composition of a product : ingredients, detected ingredients, traces, allergens

Ingredients
Do not make the assumption that the ingredient is or is not present based on this. Parsing errors happen.
List of ingredients on a specific product
  • On a product ingredients_text contains the text of the ingredients.
    • ingredients_text_fr, ingredients_text_nl… (the package of a product may be multilingual)
    • ingredients_text_with_allergens_fr (same with HTML markup around allergens)
  • This list is parsed and we construct an ingredients and ingredients_tags list, but those will contain synonyms etc. We do not have a full taxonomy for ingredients yet. It's a work in progress.
    • ingredients
      • percent: possible detected percentage (still unreliable)
      • rank: the order of the ingredient in the ingredient list
      • id: a slug version of the detected ingredient
      • text: the raw text of the detected ingredient
    • ingredients_tags
  • The ingredients are not yet taxonomized on Open Food Facts. They are taxonomized on Open Beauty Facts

==== Nutrition values ====
===== Nutrition data =====
====== General structure ======
The nutrition facts are presented by multiple fields per nutrition fact. Each nutrition fact is presented by a key, i.e. "salt", "fat", etc. The fields can also be found in the taxonomy translation file.

The fields can have the following structure:
* key (string) - the value for the nutrition fact key (eg in json: "fiber":"0.5");
* key_serving (string) -  the value of a serving for type key (eg: in json "carbohydrates_serving":"5.82"). The size of the servig is found in the serving field;
* key_value (string)  - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
* key_100g (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
* key_unit (string) - the units used in the other fields (eg in json: "carbohydrates_unit":"g"). Possible values are "kg", "g", "mg, "µg", "l", "ml", "%" or "";
* key_label (string) - a more user friendly text explaining the 

Only the nutrition facts that are actually found on the packaging are present in the interface.

Linked Data (coming soon)

Link to Wikipedia and Wikidata

Whenever possible, Open Food Facts entities are linked to Wikidata, and in turn to Wikipedia. What this means is that you get access to a trove of additional encyclopedic knowledge about food. You can for instance get: Wikipedia articles about Camembert, the translation of salt in many languages, the molecular structure of a cosmetic ingredient…
We provide the Wikidata QID, which is an unambiguous, stable and reliable identifier for a concept that will be useful to actually retrieve info from Wikipedia and Wikidata.

Example

https://world.openfoodfacts.net/categories.json 

{"linkeddata":{"wikidata:en":"Q40050"},"url":"https://world.openfoodfacts.net/category/beverages","name":"Beverages","id":"en:beverages","products":14196}

Beverages >> https://world.openfoodfacts.org/category/beverages >> Q40050 >> https://www.wikidata.org/wiki/Q40050
As you see, you'll get a beautiful image, information about the Quality label… As Wikidata is a Wiki, the knowledge you'll be able to retrieve will increase over time.

Retrieving info from Wikipedia and Wikidata

You can use the Wikipedia and Wikidata APIs to get the information you want

Examples of things you can do

  • Provide more context and more information about a specific Product, a Category of products, a Quality label, a Geography, a Brand, a Packaging material, an ingredient…
  • Perform checks or computations by mixing Wikidata information and Open Food Facts information (and possibly other APIs)
