Important
NOTE: We're now extracting search to Search-a-licious, which has an OpenAPI documentation, an Elastic-Search backend and everything you'd expect from a modern search API.
Please send a User-Agent HTTP Header with the name of the app/service querying, the version, system and a url if you have one, so that you are not blocked by mistake*
- e.g. User-Agent: CoolFoodApp - Android - Version 1.0 - https://coolfoodapp.com
Searching for products
Generic Search
Note that the search API caches results, and to get recent edits in your search results you must add `nocache=1` to the query parameters.
Core principle: Combine tags to get custom results
Combining tags is really powerful, letting you create thousands of custom APIs for your use case.

Linked Data
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)
